The art of science communication
"Communication and art within science i'm npr. Chief meteorologist paul here with climate cats. It's a challenge to explain a complex science in a way. That's relevant to people's lives. That's why one of the world's biggest science organizations. The american geophysical union gives the climate communications prize as a top award every year. This year's winner is jennifer francis with the would well climate research center in massachusetts. She was nominated by minnesota climate scientists. John abraham with the university of saint thomas jennifer welcome to climate cast. Hi there thanks for having me jennifer. What does this award mean to you in the context of the importance of climate communication. Well it's of course. A huge huge honored to be recognized by my peers. My colleagues and i'm especially proud of the american physical union for creating this prize in the first place. Because i think the public really really wants to hear about the science now especially in these days of covert and climate change and all kinds of changes that are happening in the society to hear directly from the scientists themselves so i think it is even more important for us scientists to be able to explain the work that we're doing and that the public is paying for when you think about your fellow communicators. What skills do excellent climate communicators share. I think the best science communicators are able to take a very complicated but interesting topic and boil it down not dumb it down but boil it down so that they're talking to an audience and that audience is gonna come away with the most important information that whatever that science is saying And i think good communicators also are exciting. The people are want to hear them. And some of the best ones i think are able to impart that excitement to the audience about our audience. What communication tips do you have that. Maybe could help our listeners as they talk about climate change right so the listeners. I think are are really interested. Now we're finally getting traction with the public and with decision makers particularly when it comes to climate change and so my hope is that those listeners will will pay attention and maybe do some reading on their own and maybe cross reference and also. I think it's really important for the listeners. When they hear something that doesn't seem to make much sense to dig down a little bit and see where that information is coming from. Jennifer one of your areas of expertise is the arctic. And we've seen some dramatic sea ice and temperature shifts in the arctic this year. What specific trends are you watching in the arctic. And why are they important to all of us well. The arctic is changing just so fast and this year was an exclamation point on the trends that we've been watching as you say. The sea ice reached almost a new record this year. We're watching the arctic unfold in ways. We didn't expect to happen so quickly. There are many reasons why it matters to everyone for one thing. The rapid warming in the arctic is accelerating the melt of the greenland ice sheet which is raising sea levels. It's accelerating the faa of permafrost which is releasing more greenhouse gases into the atmosphere and it's also disrupting weather patterns all down around the northern hemisphere so it affects all of us in many different ways woodward climate research center senior scientists jennifer francis. Thanks so much for your perspective on climate. Cast today my pleasure anytime.
Who is Miles Morales in Marvel's Spider-Man?
"Games that release this week. I've been playing is spiderman. miles morales. which is the sequel to two thousand seventeen spiderman by sony and insomnia and i have to say this is miles morales story and you'll know miles morales. If you're not coming read from the movie into the spite of us which is excellent right. It might be the best. I've got the best buy movie you know. Even though it's an animated movie just fun. I think really good portrayal of spiderman it's waikiki and there's all these different spiderman anyway. This is miles morelli story and it starts with pizza parker. It's spiderman he's just. He's training miles to be also spiderman. He's not been training for very long and pizza us to leave new york city for awhile with. Mj don't know what he's doing. Yes to leave. Andy leaves miles in charge of the city s spiderman. So it's it's got this new the story and the way the people in the city react to you is kind of funny because it's like. Oh you're that spiderman a we were expecting the spider-man's zone so the city hasn't really they don't really see you as spiderman so you the new kid and the shoes and like you can do your as good as pizza. You've got the same power if not more powers because miles different power but the people in the say and not really that into him so yes to kind of win the city over and then you know early on in the game the city you know. It's very typical marvel as a. Let's say or mark zuckerberg type reruns this big tech company. And he's doing something we try and take everybody over. Somehow the miles gets about moving safe the city so it's the same game. Play really is a two thousand seventeen one you. It's the same city you know because it wouldn't be spied him on if it wasn't new york city right and if spiderman was swinging around london just wouldn't seem right to me so it could mean another universe but it needs to be in the same city right. This is the same. this is just the same. The same city was different about the map. Though is it's christmas time so it snowing and there are christmas decorations all over the city. So it's really decked-out to like christmas which looks a lot different to the spiderman game twenty seventeen which was in midsummer like right in the middle of summer so it looks different on that level but the game plays exactly the same so if you liked the game play. Is that gameplay. You know you go in. The city's missions in it. Though further the story this collectibles you can collect to spiderman and suits to collect his lows different suits that he can wear. One of. The sues is one of the coolest things i've ever seen in a game. And i was just saying to use it You know the s by into despite of us cartoons remember they animation style it it was kind of choppy but it made it what it was like because it was cool looking suit when you put it on. It makes the game the animation style so the whole game is choppy looking book. Cool looking. Because it's i don't even know how they did. They've done it like it feels like the whole of the city is running at sixty frames per second but the animation of spiderman is running way less and it's also kind of jerky but it looks like it around great be able to. It looks like it came straight out without cartoon you'll like. Yeah i can see what they're doing. It's it's weird to look at but it is cool. Because i was like. Oh the soup from into despite of us let me put that on and see what that's like and then i'm like oh now. The game looks like that animation. That's crazy so that spider man. Miles morales is out on the ps. Four and the ps five.
10 years to transform the future of humanity -- or destabilize the planet
"Ten years is a long time for US humans on Earth. Ten turns around the Sun. When I was on the Ted. Stage a decade ago I, talked about planetary boundaries that keep our planet in a state that allowed humanity to prosper. The main point is that once you transgress won the risks, start multiplying the planetary boundaries are all deeply connected but climate alongside bio-diversity, our core boundaries they impact on all others. Back then we really thought we had more time. The warning lights were on absolutely, but no unstoppable change had been triggered. Since mytalk, we have increasing evidence that we are rapidly moving away from the safe operating space for humanity on earth, climate has reached a global crisis point. We have now had ten years of record breaking climate extremes, fires blazing, Australia set area California, and the Amazon floods in China Bangladesh and India. During heatwaves across the entire northern, hemisphere we risk crossing tipping points that shift the planet from being our best resilient friend dampening are impacts to start working against US amplifying the heat. For the first time, we are forced to consider the real risk of destabilizing the entire planet. Our children can see this they are walking out of school to demand action looking with disbelief at our inability to deviate away for potentially catastrophic risks. The next ten years to twenty thirty must see the most profound transformation. The world has ever known. This is our mission. This is the countdown. When my scientific colleagues summarized about a decade ago for the first time, the state of knowledge on climate tipping points just one place had strong evidence that it was on a sears downward spiral. Arctic Sea ice. Other tipping points were long way off fifty four hundred turns around the Sun. Just. Last year, we revisited these systems in I got the shock of my career. We are only a few decades away from an Arctic without since summer in. Permafrost is now thawing at dramatic. Scales Greenland is losing trillions of tons of ice and may be approaching a tipping point. The great force of the North are burning with plumes of smoke, the size of Europe. Atlantic Ocean circulation is slowing the Amazon rainforest is weakening and may start emitting carbon within fifteen years. Half of the Coral Great Guy Wreath has died west Antarctica may have crossed the tipping point already today, and now the most solid of glaciers on earth east Antarctica parts of it are becoming unstable. Nine out of the fifteen big biophysical systems that regulate climate are now on the move showing worrying signs of decline in potentially approaching tipping points. Tipping Points Bring Three threats I sea level rise, we can already expect up to one meter this century. This will endanger the homes of two, hundred million people. But when we add the melting is from Antarctica and greenland into the equation, this might lead to a two meter rise. But it won't stop there. It will keep on getting worse. Second if our carbon stores like permafrost enforced flipped to belching carbon, then this makes the job of stabilizing temperatures so much harder and third these systems are all linked like dominoes. If you cross one tipping point, you lurch closer to others. Let's stop for a moment and look at where we are. The foundation of our civilization is a stable climate and the rich diversity of life everything I mean everything is based on this civilization has thrived and a goldilocks zone not too hot not too cold. This is what we have had for ten thousand years since we left the last ice age. Let's zoom out a little here three million years. Temperatures have never broken through the two degree Celsius limit. Earth has self regulated within a very narrow range of plus two degrees in a warm into glacial minus four degrees. Defy. Sage. Now we are following path that would take us to a three to four degree world. In just three generations, we would be rewinding the climate clock, not one, million, not two million, but five to ten million years we are drifting towards hothouse earth. For. Each one degree rise one billion people will be forced to live in conditions that we today largely consider uninhabitable. This is not a climate emergency. It is a planetary emergency. My fear is not that Earth will fall over a cliff on the first of January twenty thirty. My fear is that we press unstoppable buttons in the Earth System.
Greenland Melting Fastest Any Time in Last 12,000 Years
"Greenland is the biggest island in the world and the ice sheet that sits atop it is massive. The pile of ice is so thick that it extends more than ten thousand feet above the ocean, and if all the ice were to melt and go into the ocean global sea levels would rise by twenty four feet everywhere around the world, Jason Bryner, Geologist University at Buffalo the ice sheet is melting of course but just how much compared to the past Brenner team did a computer simulation of. The southwest portion of the Greenland Ice Sheet, which he says is a pretty good proxy for ice melt across the entire ICESHEET. The researchers plugged past climate data into that model to hind cast rather than forecast the past activity of the ice sheet, and they then checked the predictions of the past shape and size of the ice by looking at piles of rocks and boulders and dirt on Greenland, today, which outlined the edges of the ice and the simulation was in good agreement with the actual situation. Using that require. -struction of the ice sheet over time the team could then compare the ice sheets historic losses to those happening today under human caused global warming, and they determine the greenland is contract to lose more ice this century than during any century in the past twelve thousand years possibly four times as much ice. The results appear in the journal Nature. Ultimately it's up to us how much ice melts you know humanity has the Knob the carbon knob and that knob is going to influence the rates of Iceland. Greenland. Ice Sheet. If the World Goes Net Carbon Zero by twenty, one, hundred, for example Bryner says ice loss could stop entirely at the end of the century according to one model that was what kept me from being completely depressed about our study. Dozens of countries have already announced goals to go net zero by the middle of this century so far the US is not one of them.

Humans Have Caused the Most Dramatic Climate Change in 3 Million Years
"Recently Assad with some research colleagues at the Potsdam Institute for Climate Impact Research, a look at a brand new science article in which are climate model for the first time had recreated the climate on earth over the last three million years, which covers the entire geological pleistocene epoch. The Pleistocene is so important as it constitutes a point of reference for life on. Earth. Because although sure our planet has existed for four point, five, billion years it's only in the last million years. That earth has looked at least roughly in the way as we know it, the continents were roughly where they are today. The North and South Poles were covered with ice. The atmosphere had a similar chemical composition to what we have today. Planet, Earth. Our earth has only existed for three million years. All, comparisons further back in time are quite meaningless. And the manuscript I hold in my hand is not just reaching. My brain is also striking straight into my heart. A deep humility settles in when look at the graph showing the variations in mean global temperature on earth over the past three, million years it shows that we have never throughout the whole plasticine exceeded two degrees global warming compared to our pre industrial average temperature of approximately fourteen degrees. Never. This means that Earth despite all the stresses and natural shocks from fluctuations and Solar Radiation Volcanic eruptions, asteroid impacts and earthquakes has regulated itself within an incredibly narrow range minus four degrees. Celsius were in deep ice age plus two degree Celsius. We're in a warm interglacial period lasting three million years. It's absolutely incredible. Especially since we know why. It's earth's ability to self regulate the ability of the oceans to absorb and store heat the ability of the ice sheets to reflect solar radiation the ability of the forests to absorb carbon dioxide and the ability to be a safe and store greenhouse gases. The planet is a biophysical self playing piano whose music sheet stays. Within the minus four plus to scale. If that is not caused for humidity than I do not know what humidity is. And a deep concern in hundred and fifty years. In the geological blink of an eye, we risk now tearing this Planetary Symphony to shreds. Let that sink in. The global average temperature is now changing hundred and seventy times faster than over the last seven thousand years and it's doing. So in the wrong direction upwards when the current orbital forcing meaning are distance to the sun and the current low level of solar activity means that the temperature should in fact, be slowing down. You don't have to be a physicist to understand that we have a problem. Climate skeptics like to argue that historically the climate has fluctuated so much. So why shouldn't it be fluctuating now? Obviously. It fluctuates. But we are now racing towards plus three to plus four degrees warming. Sceptics like to bring up the little ice age the time when Swedish King Call The tenth Gustav Marched His army across the deep frozen great belt and the little belt in sixteen fifty eight to beat the Danes or that the vikings grew grapes in Greenland during the medieval warm period. Yes. Of course, this is true but it all occurred within the natural boundaries of minus four and plus two degrees. And it's here within this sweet spot that we must remain for our own sakes and our future? In August two, thousand, eighteen at the peak of that year's drought and fires in Sweden and Europe. We published a scientific paper where we tried to establish whether we are at risk of pushing the entire planet away from its current state of equilibrium, the Holocene epoch where we have been since the last ice age. This is fundamental. Our Planet Earth can be in three different states. It can be in a deep ice age as it was twenty thousand years ago with large is. Extending over the northern and Southern Hemisphere with over two kilometers of ice above our heads here in Sweden an ice extending as far south as Berlin. This is an equilibrium state as it is not only lower solar radiation that keeps earth in an ice age. It is also the feedbacks caused by ice. As the ice sheets grow earth gets whiter, which means that more more incoming heat from the sun is reflected back to space more ice means it gets colder which means even more is and suddenly you have a self reinforcing mechanism. This is what makes an ice age and equilibrium earth remains. They're not only because of the external forces from the sun but also thanks to these inbuilt biophysical processes in this case, the color of ice. Earth can also be in an interglacial an intermediate state, which is what we have today where was still have permanent is sites at the polls and we have glaciers on land and the biosphere with forests, grasslands, and lakes roughly as Earth as we know it. It is these two equilibrium states and only these two states that the planet has been over the last three million years that is during the entire Pleistocene. But then there is a third state when earth tips over from self cooling feedback loops to self heating feedback loops, which leads to an inevitable journey to becoming a hot tropical planet that is four, five, six, potentially seven, eight degrees warmer than today where in principle, all the ice has gone and the surface of the ocean is more than fifty meters higher than it is today and where the conditions for live is fundamentally different all over the entire planet. This is what we call hothouse earth. Or Highs Zaid hot time in German where the article when we published it drew so much attention doing this burning heat wave in the summer of twenty eighteen that highs Zaid was chosen as the word of the year in Germany. In this research, we tried for the first time to identify the global mean temperature at which we are in danger of tipping over from our current state, the Holocene interglacial, and embarking on a journey that would inevitably take us to highlight our conclusion is that we cannot exclude that the planetary threshold. The tipping point where we kickoff unstoppable processes of self amplified warming is at two degrees. Bear in mind we are today at one point one very mind were moving fast along a path that reaches one point five in potentially only twenty, thirty years and two degrees in forty fifty years. This is one I would argue of the biggest. Challenges of all to test whether we are right. Can the planet cope with or Canet not cope with higher temperatures than two degrees? But. My conclusion based on the knowledge we have today is that the planetary threshold to avoid triggering high Zaid is most likely at two degrees. Of course, it's not so that Earth will fall off a cliff at two degrees. The risk is rather that we would then pass a threshold where the shift towards hindsight would become unstoppable. In other words, we face an urgency at the timeframe whether we pushed the on button on not triggering stoppable warming is within the next few decades meaning essentially. Now, if we pressed the UNBUTTON and kick off the great planetary machinery with feedback loops causing self warming, then the full impacts may play out over three four, five, hundred years before we reach a new equilibrium state hothouse. A planet with over ten meters, sea level rise temperatures, and extreme droughts, floods, and heatwaves making large parts of earth uninhabitable a planet we do not want a planet that cannot support US humans. This requires from us that we understand two different time horizons. The short term time of commitment. When do we push the unbutton but then also the long term time horizon when we have the full impact hitting on people these are different but ethically, I would argue only the trigger moment counts, we cannot leave a damaged planet beyond repair to future generations. So to summarize the decisive moment when we press don't press the button lies within the next ten to twenty years. With consequences for all future generations a moral, bum. Are High site article concluded that degree Celsius is our ultimate planetary threshold that we need to stay away from. This article actually came out six months before our climate modeling showed that we've never exceeded two degrees throughout the whole pleistocene, the last three million years. In Two thousand nine, our planetary boundaries size showed that one point five degrees is a boundary we should not transgress because then we enter a danger zone of uncertainty. So perhaps you do understand my feeling a deep concern of humility in the face of our latest scientific findings, which really only says, one thing tipping points are real and if they're crossed, they lead to unstoppable changes, which requires a new relationship between us and our planet, and that we realize that we are facing a new ethics. What we do today will determine the future on earth for all our children and their children.
The Science of Wildfire Smoke
"I. Don't know about you. But when I hear the word smoke, it makes me think of huge thick plumes of different shades of gray sort of blanketing everything nothing too complicated for somebody like Jessica though smoke is an incredibly complex mixture of different gases and particles, and if we look just at the gases, there are hundreds to thousands of different gases that are formed in biomass burning biomass, we're. Talking things like trees and brush that burn up in wildfire when it comes to particles and smoke there's also a huge range from larger ones in the form of ash dust that can work quickly settle out of the sky, but you also get really teeny tiny particles on the order of millions of a meter in diameter and those really small particles can stay in the atmosphere for a lot longer. In from the particulates side, the thing that people seem to be the most freaked out about is this pm two point five or this little the little particles that are super super small, and there seems to be a lot of that going on right now in California and like large parts of the West Right. Yeah. So one of the primary Hazardous Air pollutants is articles that are called pm two point five has a overall diameter of two and a half micrometres. This and that's roughly about fifty times smaller than a single grain of salt. So, really really small particles. The smaller particles not only can they travel further distances, but they also have this unique ability to follow the sort of micro air currents can bend around corners and edges and everything, and that means that if you're breathing in smoke, those larger particles are GonNa hit the back of your throat first, but the smaller particles can actually make it all the way. Down your throat and the deep into your lungs, and that's where they start to cause all kinds of different health effects. One of the most interesting things about smoke is how it behaves how it interacts with the different layers of our atmosphere including the layer closest to us called the boundary layer and how big that layer is how thick it is depends on temperature. So at night when? It's cooler that layer condenses comes back down in altitude also with cooler temps and higher humidity at night wildfires tend to die down and when they die down, that's actually when they produce quite a bit of smoke and not mixing into a more shallow boundary layer just means you get a lot more smoke very close to the ground particularly at night especially if you're in a kind of. Mountain valley where it just starts to pool and accumulate, and it's not really diluted or moved out of your immediate area until the sunrise comes that boundary layer starts expand the wind speeds, pick up and kind of take the smoke away. Sure. Yeah. I guess I didn't I had no idea that you know in areas where there's wildfire burning but the smoke actually kind of settles back. At night and it makes me think about like you know it's night. It's cool. You want to open a window, right? That can be problematic. It is yeah, and that's and that's true of most air pollution sources but particularly. So for smoke many of the Western states even here in Colorado, it's not necessarily all that common that you have air conditioning It does cool down quite a bit at night and so that is the time people will turn on fans. Etc Try to ventilate the house. Get Cool at night a course your home. At night sleeping and breathing off through the night and so again, that's one way that you can be exposed to smoke that you might not necessarily think of. And so I think it's important to remember. Right. So we're looking at areas like California and Colorado were seeing them on fire. We're seeing the smoke in all of this smoke doesn't just hang out there right? Like smoke really travels. Certain smoke plumes can literally travel the world and go to really remote places, and of course, with fires were we're impacted here in the United States right now. But of course that flips as we go to the next season and then the southern hemisphere so fires just a constant emission source across the globe and as I said as it. Gets admitted and the the different layers of the atmospheric and stay in the atmosphere longer, and that just means it can get carried by the wind currents further and further down wind, and so I've been looking at the different fire models and stuff that knows producing and can see that right now even the most of the fires are certainly on the west coast. To. percent or more of the continental US seeing the effects of this smoke. So even you know my family who lives in Ohio can go out and see these red sunsets potentially from smoke that's being emitted out in California and Colorado, and so that smoke can just travel tens to hundreds of miles down wind from the source. Yeah. Yeah Okay. So we have this smoke right and it's all over the West You know how does the smoke leave? Jessica like how long are people in? California people where you live in Colorado going to be living under these like poor air quality conditions and yes I am asking you to predict the future. Well that's what I'm best at so. The do things that will determine when residents particularly of California those most impacted by the smoke we'll get some relief is, of course when the fires go out and with that, you'll need a change in the weather patterns. So some rain to help. Put out those fires and even if the fires are going. Again, shift in the wind pattern can help. Move. Some of that smoke out away from them but all that means is somebody else will get impacted by that smoke. So one of the things I always try to remind folks is that we all live downwind of somebody. So it might be great air-quality where you're at but you know if there's another emission source just behind you gonNA impact your neighbors, and so in that regard California might get some relief but then maybe Idaho or Montana. Now gets inundated with more smoke there. So that's the sort of immediate way that you can reduce your exposure to the smoke. But in the atmosphere and the only way smoke is truly removed as if it's really out of the atmosphere and it's Not. Necessarily destroyed it's just removed from the atmosphere. You know the kicker is though when this smoke maybe clears up from way that we can detect it like just by going out and be like, Oh, I can breathe a little bit. It never just disappears right like you know smoked feeds into this cycle of climate change, right? The primary component is going to be related to those particles and so particles or something that can both. The climate as well as heat the earth, and so that's where that size and color of the particles really comes into play and so the white. Particles that you associate with clouds generally reflect radiation back to space. So that's a cooling effect rate. If you're under a cloud on a super sunny day, you immediately feel better in cooler on when that cloud is overhead. The other ways, the those darker particles, the black soot those are things that are readily absorb radiation from the sun, which means when the sun goes down. They can also re admit that radiation back into our atmosphere, and that's what contributes to that the global warming effect, the greenhouse gas effect the so important for climate change. So that's one way that the aerosols play into it right and all of these things kind of feed into in this is simply put these things feed into a longer hotter fire season. So it's kind of this garbage cycle. Unfortunately. Yeah. We call that a negative feedback cycle. And so. Those particles that are released from biomass burning may of climate and climate continues to change which could lead to more fires and so forth. You just get unfortunately negative feedback. We're just continues down the wrong path rather than trying to correct itself or balance itself out. You know I feel I feel like the wildfires and the smoke are very visual examples of climate change I. Mean Do you think that these fires could impact how people are thinking about climate change and what needs to be done? I. Hope. So I mean there there's many difference. Really visual ways of seeing climate change with our own eyes. I mean from the rising sea levels and daytime flooding that's happening and some of the coastal cities to the amount of runoff that you see on the Greenland ice sheet to these huge you know ice shelves claiming off Antarctica I mean the signs are all around the biometric burning is certainly one that impacts. You know a large community of people out West and as you mentioned, it's a very visceral response and then with climate change, you often hear of global warming and of course, fires represent that heat. And so that's certainly a connection there as well and so. I can only hope that people start to think. About how much their lives will be changed as our climate continues

"About ninety percent of the freshwater in the globe is tied up in the Arctic. Ice Sheet about nine percent in Greenland ice sheet but Antarctic is right over the South Pole Greenland. Actually the extends quite far south down well below the Arctic circle in fact the southern tip of Greenland is comparable to some of the capital cities of Scandinavia address. Awesome latitude you if you fly from Europe to the US Green on noticing that in the past exactly high flow of their over southern Greenland en route to Europe before as well Al and so because it sits relatively relatively low latitude it is much more susceptible to melting than most of the Antarctica. She does now. There are other reasons why we might be why we are concerned about the Antarctica sheet as well But just in terms of the the summer melting that we see it's much more pronounced on the greenland the Nike because of the relatively low latitude. No I know. We're doing a multi part series on greenland for the weather gets podcast and we spoke with Dave Malkov who spent some time. I am on a glacier there in Greenland I. I don't even know if we're gonNA PRONOUNCE IT correctly. But during my time at NASA colleagues were talking about the is it starts with a J. Kayce often jockettes Saban glacier and I know that people have been monitoring its rate of change if you will How is it and other glaciers doing general greenland so we've seen Over the past few decades and accelerated loss of mass. So when you think about we talk about the mass balance of the Ice Sheet we have snow that lands on in on on on the surface of the ice sheet eventually compresses into fern and then glacial ice and then we have two different ways in which we can lose ice we could have melting of the surface that meltwater L. water forms rivers drains into what we call mullins which actually holes in the ice drain down to the base and then usually it comes out beneath the surface of the of the ice sheet along the margins the other ways that we can calve off icebergs at the margins as well too especially for glaciers that end in Marine Marine Marine terminating glaciers and in the Ocean Yaacob Saban is one of the fastest moving ice streams on the globe so the ice itself. I always tell my students. It's not like a giant. Ice Cube cubits dynamic. It's flowing out to the margins. Some of these areas are flowing very fast. Some of them are flowing fairly slow. Yaacob Savas an area on the west coast of Greenland where the ice is moving very very fast. And it's a beautiful area. If you get to go to the town of yaacob Saban Disko Bay area there. there's a hotel. Tell the Arctic Hotel where you have this beautiful beautiful view actually of the ocean and all of the icebergs capping off into the ocean there But it's actually said that there's no way to really know this but it said that the iceberg that sunk. The titanic probably came off the Nice little weather Geek tidbits that you might not hear anywhere else. I actually want to use this last segment of the the podcast. Now because Dr Modes an expert Chrysler Processes Greenland and whatnot. But I I know because and colleague of his first of all he does a lot of other interesting things so talk about some of your more recent research that is not necessarily cry for for example. I know you're involved in and let me by the way. Dr Mona has has worked funded by NASA Noah National Science Foundation. US Far Service and and many others. Because you know he's been able to to successfully convey his science and it's dutiful and useful science and so he can acquire funding and so he uses satellite perspective uses uses remote sensing a operations models so forth. Talk about what you're up to in Puerto Rico. That's been a threat of research so we've been involved in for about the past last six or seven years now was actually a project. I believe that they originally wanted to entrain. You say by the time are you were you were tied up they were. They were very interested in looking at the influence of climate. Change on these these rich areas of biodiversity in eastern Puerto Rico in the Luquillo mountains near San Juan. So if you've ever had a chance to go to San Juan maybe you've been there on a cruise ship. You could actually look out in the distance and you can see these mountains in an often. People visit Puerto Rico will have a chance to take a visit. Have a chance to go. Inland and visit these mounds really Stunningly beautiful area But the question is how is climate change influencing ecosystem of these mountains and so our task with his Long Term Ecological Research Program at Luquillo. Puerto Rico has been looking at Particularly the role of drought and hurricanes on On on this really unique setting a one of the things that we've done recently was to look at you mentioned Saharan dust earlier. We've been looking at the role of Saharan dust in producing producing droughts in this region And we're continuing to to Look at other mechanisms associated with drought in this area. Too because we do expect. The droughts will become more frequent and more intense with changing climate in the Caribbean particularly. This part of the Caribbean. Yeah and I think Dr Mo makes a great point about Extreme events and sort of this notion retribution sciences which is becoming quite a significant in the research field what we expect to happen happen in current or contemporary extreme weather events and I based on things that I've talked to him about before. That area is a particularly sensitive area in terms of drought to some of these changes. We're we're seeing we. We are winding down now. But I I want to ask Dr Mo the put on his sort of bigger picture here. He's a leader in the field. I mean he's A. He's a leader in science sci. He's been on sort of the Executive Council of the G in has all of these awards. He's an associate dean at a major research university decide. I want to just ask one final question. If you're talking to the broader public what would you say about the importance of in and I know you're in your portfolio Roleo. Uga You deal with the sciences. Would you say about the importance of scientific research and development. And how does that sort of get to their lives. What are the what is what is your view on the overall research enterprise and I just think people we are very familiar with it? But I'm always interested in thoughts colleagues about how we can convey to the broader public imports. The research I mean is really the oh I mean it's the Beckett is that we have to learn about the world around us so I mean I think particularly in this time it's really important to talk about evidence evidence base whether we're talking about social systems whether we're talking about natural systems The the importance of of really carefully scrutinizing evidence that's available I mean this comes up in the climate change debate. There's a I I know you hear this question more often than I do. Do you believe in climate change. But it's it's not a question of belief it's a question of looking at evidence and we're evidence points us and that's what really signs is all about is looking at critically looking at evidence evidence Drawing hypotheses testing those hypotheses based on that evidence and taking us where it leads us on a place like the univer again. I want you to where your university university had a little bit of places like the University of Georgia. Since that's where you are I am. How does that a university and we'll use that? I mean we're talking about any university how they play a role as a university because it's more than just teaching students which is a valuable part of our mission. But how how the how the universities sort of inject this knowledge allege into the state local national international sort of stakeholder and plum practitioner practices. If you will you know it's interesting. I think particularly as a public institution more The first State Charter University in the in the country at the University of Georgia and particularly as a as representatives hundreds of public institution. I think we have an obligation to the people of the state of Georgia People more broadly but particularly the people of the state of Georgia to share. What we've learned it's not not enough for us to just kind of keep it to ourselves And I think that there are many ways than we do that I think the University of Georgia for example has a really tremendous public look service and outreach function that reaches touches all corners of the state. And so I'm constantly impressed by my colleagues in the work that they do in in what we call our PSI unit. I think the kinds of things that you do whether through this podcast or the other kinds of outreach activities that you were engaged in that are more for broad-based based publicly focused I think are also important I think the many of our colleagues are actively reaching out in the popular press as well L. Too. I think all of those forms of engagement are really important. I don't think there's sort of any one particular form of engagement that is privileged your most important. I think all of the above approach here in terms of really communicating the science. That that we're working on to the to the public the public of our state absolutely I uh I know you're on twitter. And what's your twitter handle of people WanNA follow you at T. L. Note. Okay not at Te'o mode so definitely give him a follow and Tom. I want to thank you as a colleague.

"The ice sheet. And we are talking with Dr Tom Mode as we come back to the weather. Other GEEKS podcasts. He's a distinguished research professor at the University of Georgia's Associate Dean in the Franklin College of Arts and Sciences and has received numerous awards for his work over the years in climatology geography atmospheric scientists and so forth really honored to have him here today because I consider him one of the world's top experts on by the way you can check out a couple of pieces that he wrote in the hill which is a journalistic outlet and they sought his expertise during doing the twenty one thousand nine hundred post two thousand nineteen melt events so if you want to read a little bit more about some of his store thoughts on this most recent event definitely check out now his work and writing in the hill so If you just do a google search on Tom Odin the hill. I bet you find it now. I WANNA come back to some of the more local and regional impacts on these melts events for for example when we get these melt events how is it affecting the local ecosystems or perhaps even the marine environment so we we actually had a a very interesting project with my colleagues Tissue Hager Renato cast allow at the University of Georgia and colleagues at Stanford University Columbia University and Rutgers University. I was supported by NASA where we were looking at the interaction between climate greenland mass balance. Run off of meltwater the ocean circulation and the nearby sees and then ocean productivity Really really fascinating work. I think showing that when we see these large runoff off events from Greenland. Of course there's freshwater goes into the Atlantic Ocean It influences the the essentially the depth of this Freshwater freshwater layer. This creates this freshwater lens at the surface that affects essentially the ability of phytoplankton to To be productive and so A very complicated picture. Because it's not just related to the amount of meltwater that's running from the Greenland ice sheet but it's also related to wind patterns and and the resulting ocean circulation patterns as well too But we certainly do see a significant influence of Greenland meltwater runoff on ocean productivity in Baffin Bay for example Labrador Sea. And it's really interesting. This is something that may be lost on people that just. Don't don't think about these things every day but the differences between this sort of influx of freshwater into the ocean which is a saltwater system has significant influences on things like the large thermal hailing leaner conveyor belt circulation. If you ever saw the movie the day after tomorrow That movie was talking about the sort of disruption or shutdown of that circulation in the world. Weather were crazy and of course the things that happened in a move your Hollywood. They're not gonNA really happen at that scale. But it's important to sort of note that by the way another the weather geek tidbit bid just something I do. And I'm just a geek like that. Sometimes when I go to restaurants I will take the glass and mixed Diet Soda with sort of a very sweet so to like a mountain dew. Do and just because they're of different densities. Watch what happens when you put one in. I put the other in and you can see the difference in densities and we're talking about fluids and so some of those it's simple concept of what we're talking about. We talk about fresh water and salt water. Now the producers actually wanted me to ask you about the connection Saharan dust list to greenland. Yes this was sort of a some research that Just an opportunity that came out of the blue with a colleague at And why You New York universities Abu Dhabi campus. They have a center for sea level research located there. They have a scholar there who was looking at Saharan dust transport report and she was noticing this dust transport actually into the North Atlantic across Europe and wanted to determine what kind of influence there was on melting the process on Greenland. I mean the surface agreement is she does very sensitive to the reflective veto snow obviously very bright reflective once it starts starts to melt and refreeze becomes a little bit darker absorbs more energy. Eventually you melt away all of the seasonal snow cover you get down to glacial ice. It absorbs even more energy but we also have other sort of contaminants if you will whether at the Black Carbon from fires in the Arctic weather. It's Dust that might be in this case. Come from the Sahara. Another actual Something else that we're really interested in that has a significant effect on the reflectively. Activity of the ice is blue green algae so we see cyanobacteria and that has a very large influence on the reflectively. So there are areas. Appreciate that have been documented does darkening over the last several years now Saharan. Dust is probably not the most important player here but people I know you and I know a colleague Jason Box that talks about suit in sort of black carbon. Jason has been looking at black carbon. He's also there. There are others Colleagues I now I was just talking to when I had a recent visit rutgers university diversity. We're looking at the influence of cyanobacteria on reflectively Particularly within these river systems that develop on the surface of the ice as it starts to melt in the summer Jason Box who used to be at Ohio State University is now at the Danish Meteorological Institute And the University of Copenhagen he Actually has a satellite product where he looks at how bright the surface of the ice sheet is and he's been able to clearly document darkening of the surface of the ice sheet over time as we've seen this increased melt. Take your your eyes are. Your eyes are sensitive to some of these very processes that we're talking about a very bright sunny day and yet a fresh snow cover. Are you ever heard of the concept of being snow blind. And that's because of the High Albie reflective of snow and you're I is a remote sensor. It's this using the visible where somebody's satellite so using different parts of the electromagnetic spectrum so this is really a good discussion of how we use some of those remote sensing techniques to study various aspects of the the system system. Now I want to kind of shift to sort of a final phase of questioning. I WANNA stay in crisis for your second name. We're going to go some different places but again whether we really do like to geek out out in sort of educate our listeners. Talk to.
"greenland" Discussed on Weather Geeks
"Rings. And I often get that question. And they're quite accurate. Would you when you get the question. How how accurate are these ice cores? What do you say I mean it's you can see very clearly the annual newell layers in these cores going back for Many cases thousands of years We could also date these quite accurately. There's certain events that we know so in terms of volcanic eruptions or even nuclear testing. We can use to date very particular years in those records and then going back further in time we have enough. Ah other kinds of records that you can put them together and get very accurate reconstructions of dates certainly within the past few thousand years and really very accurate reconduction reconstructions much further back in time. That talking with Dr. Tom Mode climatologists at the University of Georgia one of the most significant scientists look to be a fellow of two major professional all societies as a significant honor. So I always liked establish that you hear here on whether we're getting experts that can cut through a lot of what you might hear about the science and give you the the science as you need to understand in here it's a we rethink doctor. Tom Over taking time to appear on weather geeks. I want to shift a discussion. To sort of causation. With with these melt events these episodic events and then perhaps the longer term changes. Because I know from some of your work that there are these things that are happening. In the atmosphere we can geek out onto weather terms talking about atmospheric rivers and blocking highs sort of weather related. So let's talk about sort of perhaps these sort of short term weather related influences influences on these melt events and then maybe a larger context climate change. Certainly I mean a lot of our work. In the last five years has really been focused on looking at atmospheric blocking patterns Saturn's and how they are associated with Large Melt events on green that we know for example with this twenty event that we saw very pronounced atmospheric blocking blocking pattern that set up across the North Atlantic. Now when you say blocking pattern for those that may not know what a block or are you talking about a large blocking high. So we're talking about a large blocking Ridge located it across the North Atlantic Persistent in time Bringing in many cases You know on its Western flank. Also affecting lar- warm humid air masses up across the ice sheet And and we see these blocking patterns tend to be very persistent across greenland and when we have a negative face to the North Atlantic Oscillation. Now there's a nice geeky term that we probably need to spend a little time onto. What's the Arctic Oscillation? Well in this case we're just talking about the the North Atlantic Oscillation which is related to the okay and the North Atlantic. Oscillation is essentially a seesaw in pressuring temperatures between the Sub Tropics of the the Atlantic in the higher latitudes of the Atlantic and so when we have a positive phase we tend to have higher pressure and warmer temperatures in the tropics when we have a negative as we tend to have higher temperatures and higher pressures in the northern portion of the Atlantic. And we we see that we tend to see these persistent blocking patterns occur that are often often if they occur in the summer or often associated with large melt events in large mass loss events across greenland. So that's one of the things we've looked at. And then with one of my former PhD HD students who is now at Rutgers University. Kyle mattingly. We've been really looking at these. Atmospheric River Events So atmospheric rivers are a phenomenon especially those in the Western. The United States are very familiar with think about the pineapple express bringing in these plumes of moisture into the West. We also know that atmospheric rivers are very important for injecting moisture into the Arctic. And we find that when these atmospheric river events are active that they're bringing in at they're bringing in warm air but they're we're also bringing in in many cases thick low water bearing clouds that are also very important in melt processes in the ice sheet because these low oh liquid liquid phase clouds Produce a lot of down welling long wave energy that helps keep the ice sheet warm and leads to these. He's melt events right. So we see that there are these meteorological connections and so important point. I want to make here because there are some in the world that say climate scientists Sir overreacting and they sort of just jumped right to the climate change Lincoln. Now what you just heard Dr Mo talk about sort of atmospheric circulation relation and patterns that we know are associated with these melts events and you had mentioned earlier this. Most recent event in two thousand nineteen was very much related to the extreme heat wave in Europe. And I'm sure that's related to the the Ridge blocking pattern that you heard him talk about however we cannot sort of divorce ourselves.

"Use of other kinds of satellite data like landside imagery. And we know that through the nineteen sixty s and nineteen seventies nineteen eighties that Greenland was. Roughly in balance it was gaining about not as much is through. Snowfall was losing through melting icebergs calving off but again since about one thousand nine hundred. We've seen a very significant loss of mass us from Greenland on the order in the past decade or so of about two hundred and eighty giga tons of ice per year. Roughly takes about three hundred sixty giga tons of ice tweet Equal One millimeter of sea level rise. So yes so. There's there's the so what I think. Many climatologists see Greenland and and West. Arctic ice sheet and others as sort of bellwethers canaries in coalmines. If you will I know some people are wondering because you mentioned past melt events before we had satellites. How do we get that type of information? Before the era of satellite so a couple of ways one is that we have we do have temperature records and we can use those temperature records with models that we have to be able to even though the temperature records themselves are the long term temperature records from coastal stations. That are not on the ice sheet. Only there's about ten percent of them. The margin of Greenland has not covered by ice. But we can use that with models to You you know to reconstruct what the melt record looked on the ice sheet but we also can look at course you can actually look at annual layers in the ice cores and you can see where there are melt layers that formed. That's how we know for example that this twenty twelve event and again twenty nineteen event that occurred at the top of the ice sheet. We know that there were previous melt events again in the eighteen eighties and then back Prior to that during essentially the medieval warm period yeah and these climate proxies are very commonly used using climate science. We use ice cores. We have a colleague at the University of Georgia that core does lake sediment cores tree rings. And I often get that question. And they're quite accurate. Would you when you get the question. How how accurate are these ice cores? What do you say I mean it's you can see very clearly the annual newell layers in these cores going back for Many cases thousands of years We could also date these quite.

"Hadn't really been doing any work on this in real time basis and of course we're we're looking at other aspects of climate associated with Both energy and the mass balance of the green dice sheet but I I hadn't been working in Greenland England I hadn't been working on side during the For a number of years leading up to twenty twelve I had a colleague of mine from Rutgers University away still continue to work with Mussa runner. Mom She happened to be working on the ice sheet at that time and she actually contacted me and she reached out and said you know. I'd like you to look at the satellite data real time because we're seeing something really really remarkable happening here the Watson River which is a major river that runs past a former. US Air Base at the formerly the Saunder. Strong airbase now the Greenlandic Greenlandic town of Kangerlussuaq saw the bridge. This bridge had been there for decades. Wash out this bridge washed out from meltwater coming off of the ice sheet. Said you need look at the satellite product and see what's happening and so we took a look at it and saw that essentially the entire surface of the ice sheet was melting. And something that we hadn't seen before including even even up to the highest elevations of the ice sheet that reach over ten thousand feet. That's over ten thousand feet above sea level so these are places where the average temperature is something like minus minus thirty Celsius and these are very called areas And you know we went on to publish some work from that. And some of the some of our colleagues who've who've looked at some of the ice cores from the what we call summit the highest elevation of the Ice Sheet. We're finding that they had not seen any ice layers that had formed Prior to this event Since the eighteen eighties and before that we think the last time that we saw melt event at the highest elevations of the she probably was somewhere around the year. Lebanon hundred so this was really an unusual event and anomalous event and certainly there is evidence that you've seen it before in the natural record because I know that there will be some. Okay well. I'm sure this has happened naturally. And I WANNA Kinda get into this sort of natural variability to weather related aspects of this and the climate change aspects but fast forward to recent sometimes as well and I'm going to read some notes provided by our producer of this particular podcast. They are dealing hand was a former student of both of ours. Yes they are dealing ham here at the at. The Weather Channel Sarah Rights on June thirteenth of this year twenty nineteen greenland experience more than two GIG tons of ice melt in one day you you were quoted in an article saying that this was unusual but not unprecedented. Now you've just given his contacts with two thousand twelve event tell us about why or how this more more. Recent event fits in the context with that event and other events. This year was a very interesting summer. So we had this very large melt event in twenty twelve in fact if you look at the amount of melt and the amount of mass loss from Greenland. We've seen this really accelerating loss through since about nineteen ninety eight and really peaking in twenty twelve. We saw a a year following that in two thousand thirteen. That was much cooler than we've seen in the past. Two decades are most for the past two decades but then again seen a number of years with Greater than average melt and greater than average loss of ice from the ice sheet but this year was really kind of unusual in that we saw a quite a bit of melt occurring on the sheet. But it occurred mostly very early in the summer season again really late in the summer season so we had this really large melt event loss of a lot of ice in early June. We typically you see a peak and Mel sometime around the beginning of July usually the first two weeks of July and we had fairly typical conditions this year but then we had a really large melt event again at at the very end of July and the beginning of August sort of which is sorta tends to be toward the end of the melt season in Greenland. That later event was particularly interesting because because it followed immediately after the European heatwave that occurred in late July so if you may remember we had this heatwave that occurred temperatures well above one hundred degrees Fahrenheit in parts of France France the Benelux countries across much of continental Europe. A few days later after that we saw another melt event across the started in eastern part of Greenland. Most of the time these melt events come across western Greenland move up higher and higher elevations. This one came across from the East eastern Greenland and. Actually we saw again melt at the highest just allocation of the ice sheet. This summer But we were able to go back. We've I'm I'm doing some work with students now. We're actually have been able to go back and track. The origins origins of this late July event to the European heat wave awhile and we are back on the weather. PODCASTS awesome talking with Dr. Tom Moat from the University of Georgia about all things Greenland from a science perspective He's studied greenland from satellites. He's been on on the Greenland.

"Has been properly acknowledged for that and in many ways now. If you visit the website I believe in s I d. He stands for the National Snow Ice and data center or something close status reason. I bring that up. Is that oftentimes one of the satellite. Based products that They use on their website to monitor diagnose whether Greenland's undergoing melt or any sort of anomalous mel periods is a product that Dr Mode and his group at the University of Georgia's producing using satellite. So let's just geek out on a one to one level because weather geeks listeners or crawl across the spectrum first of all how are you using satellite data or satellites to detect melt on the greenland. Ice Sheet I mean just the basics of that sure we're using microwave link AH wavelength radiation But unlike a say a weather radar where you're looking at an admitted pulse and you're looking at the back scattered energy in this case we're looking at the emitted microwave microwave energy from the snow and ice surface and you know snow and ice surface of Greenland. Obviously it's very cold. You have average temperatures that are well oh below zero Celsius but when you look at the microwave energy that's emitted from the ice sheet. It typically looks even much colder. It looks like the surface of the I should be something like minus one hundred Celsius when we know. It's not quite that cold. And so in fact what happens is the individual snow grains on the surface of the ice sheet will scatter scatter that radiation. So it doesn't it doesn't Travel upward toward the satellite. And it. It makes it look like the surfaces very cold but as soon as we start to see a little bit of melt on the surface of the ice sheet that effect quickly ends and it looks suddenly much warmer Closer the freezing point so we can see that really rapid increase in what we call the brightness temperature the emitted microwave energy from the surface of the ice as soon as melts starts. And so we've been able to use that going back to the late nineteen seventies in fact even with an earlier instrument to the early nineteen seventies to essentially map. How much of the surface of the ice sheet is melting on any given day gray and I know that I? I've been aware of your work for some time and I I know there was a particular event I believe it was two thousand twelve hundred twelve July twenty twenty two thousand twelve. There was a and I remember this kind of unfolding in real time because I remember talking to you a little about it as I recall I. I think you're even surprised at some of what you were saying. Can you walk us back to two thousand thousand twelve and why that particular melt of in Greenland Greenland with so significant and alarm. Scientists certainly You know I had been looking at mapping the surface purpose area of of The surface melt and the ice she'd sort of After the fact I hadn't really been doing any work on this in real time basis and of course we're we're looking at other aspects of climate associated with Both energy and the mass balance of the green.

Climb Mount Kilimanjaro. Majora spock's conversation Certainly inspired one of group members Ian to rethink climbing. Because he's dead did it when he was young. Many many years ago we they to in spy fill is absolutely. That wasn't convenient you. I'm just wondering what do you mean really are rethinking as in history because dead. It did because he's dead. Did it picture of Perry. Who's just donors suddenly? It's achievable Altitude sickness yeah. She's doing it and found. The toilets are pretty gross on the way clay up needs outdoor and adventure travel writer. He's kayaked the fjords Autzen Greenland absolutely and we. I actually got did took us a couple of days even actually get to see the the actual ice sheet because we were used as we got into the fjords we were paddling. And all of these chunks of ice and icebergs ranging from the size of buildings and houses down to the size of cars and even and basically like the ice cubes in your glass You know we got to a a a section of the yard and we took a hike and then we actually got to see the the large glacier that Kinda came about a series of glaciers that formed the Lord's ice sheet that ran like I think fifteen hundred miles north of their size big joint or he's as an quite a large plight. Yeah it is. It's the I guess. The the world's largest island and I had to fly all the way to Europe to get back to Greenland which is actually on the North American continent. So that was the beauty of it is. It's kind of remote. It's kind of a been an article as well. I almost think it it was actually harder to get to greenland than it wants to get an article which is a spectacular. You know I was actually on an expedition cruise ship and Artika so assault. Many more people roll a metre even though it was only like maybe three hundred people owned the on the ship. But when I was in an an green on it was like me A couple of other guys and then and our God so I saw four people for the or the bulk of our kayaking Porsche so I saw less people in Greenland than I saw an an article. It was a it was actually a very unique experience to to be there and it's just a once again. You understand how you have to have a real sense of survival and kind of just a knack for wanting to to live and thrive in a very inhospitable environment. I've got this image inside my hid. About what a peddling up a field looks like an eye steep sided jeffco image. I've got is it like that or the other a bit more open as you pedal Yup yeah. They're they're actually pretty. These were pretty open to some degree. Then you got into the The fjords of Norway were jump. You you know high mountain peaks that come straight down into the water and It was a little bit more open than that. It was but yet it was still pretty much The sides of the fjord kind of went up a little bit High the peak sworn is high on on the sides. So I guess it didn't seem as as tall and kind of rugged but yet there's no trees in Greenland most of its shrubbery. That grows really low to the ground due you to the to the environment so yeah it was more of a almost like a Tiger most like a Tundra type experience pretty of today and Wildlife Seals Caribou. Most of it saw a lot of birds. We saw some Some Eagles and what southbound bear unique was that the the water was almost jet black. I guess maybe because of how deep it was or whatever then you got like this is and then you. Can you know the different colored. Is You know the bluish the Hawaii. So it's it's a very dramatic landscape. It was like it almost was kind of eerie. You know as you're paddling along in this lack water and then you can hear the ice cracking. You're not really you know you don't have any other sounds coming in from other communities or you know any any any other outside noise. Whatever you're hearing is like the the ice cracking or melting or the ice turning in the water is it's it's changing its form orm? Will you afraid of ice. Carving and cassette can be really dangerous when a big chunk of water. Well we were. We actually could not even get into the opening to that in particular fjord where glacier that was producing all the ice because it was so congested But we did take out a hike. To the top of the weekend. Came ashore ashore then hiked up to the top of this Bluff were able to see the actual the end of the glacier. It's actually capping off. You could hear it you could. It was pretty dramatic but then you could see how congested it was all trying to go out like this little bottle neck and so is it melted or is it tied change changed. It would kind of allow some of Kinda get pushed out in his more ice was being pushed off of the glacier. It would candidate push more of it out of that that small the opening it was almost a unique experience. I've seen the calving in Antarctica and it was much more wide open as opposed to these narrow channels. We now. Oh It's pretty remote in this. You know. Many towns villages along the it's a heady prepay. Faw An expedition like that. I come from a kayaking background and a sea kayaking instructor saw had a little bit of a a little bit of a head. Start ahead of a couple of the two guys that were with us when they were kind of newbies to to that so of course the the guide service we went with a headache everything. We needed paddling jackets. I even had the little peddling hoagies little myths that you would over your paddle just because of the the watertown. We had the spray skirts to keep any water out of the cop yet because the water itself as you know you could easily get hypothermia really quickly quickly and you know he obviously went over instruction somebody does go in the water. You know we all go ashore to the quickest point that we can get to immediately. After can we get the person out of the water. Because we've obviously got to build a fire Get them warmed up. Get Out of their wet clothes. Get him onto some dry clothes. Obviously you know that happened It was a injury free risk free trip so I've just jumped onto youtube and found the SI- the sound of cracking inside here. It's not ingrained landed in Canada in BC..

Conan doesn't wasn't wearing a jack so he he kind of endured an iceland greenlandic interview right and then when then something happened after that that in a way who's who's kind of a little result of the preparation we did we wrote <hes> a greeting for conan to say in <hes> three in greenlandic when we landed and we had the cue cards and the greenlandic language the words are so long vowel heavy. They're funny. They're just funny to see. Apparently greenlandic has the longest word in any language yeah. It's like multiple lines long forward yeah yeah no language language is just crazy and we ended up not doing shooting the greeting and we're like we'll. Let's grab the green in town because it's because the idea was you hear conan doing this greeting and butchering the language and then i think jesse was your idea at one point he would cut to the cue card and that would really get got a big laugh. When you see the words he's trying to actually read so then after that long interviews they asked him to do the weather or i think we'd pitched again. We pitched him doing the weather and they're like we will sure yeah so it was going to be him with the with the other weather person and she'd go and then he'd go and we you were kind of approaching it and it was getting a little like linear thinking of things to improvise and write code and then i forget who i think conan conan was just like let's let me do it. Try to do it in their language and then we're like yes we'll do the reverse shot basically jesse's idea but even funnier prompter and then it was moving it was moving and he's trying to keep up and end up being one of the funniest things on the shop yes yeah but that's an example of an really aired in greenland.

This every other day out of iceland like it'd be really really hard to get there right with a camera so very last minute and from l._a. So l._a. Especially to my three planes right we'd have to fly overplay by many hours to get to go to copenhagen copenhagen and then wait than for this one flight go back. Yeah crazy figured it out right well.

I mean it's literally like you can't tonight. Normal gear we bring our normal gear and we couldn't bring one of our one one of our cameramen and our sound nearly eleven of us go yes and so we just decided okay.

"I. I think it's not hard to find the statistics on that. <hes> <hes> portion would be in there to abortions in there as well rich people yeah. I think that's true but i think that i think that that those does that doesn't necessarily motivate them to vote in the same way i mean if you look at times where there's been depressed republican turnout the the thing that really motivates them and so i understand why attacking delib in omar i think i can come up with a plausible. We'll explanation as to why he would say this about jews because he wants to make it about israel and he wants to motivate evangelicals. I may be wrong and maybe just crazy but he takes their voting personally to right but this in a million years. I can never understand as you know. I don't know if a covered it because it was so silly. Don't trump supposedly was asking his advisers about buying greenland. We covered in the context of kudlow right right okay but it was like a side story like donald trump tweeted out this last night. There is a very special country with incredible people but based on prime minister mezei ferguson's comments that she would have no interest in discussing the purchase of greenland. I will be postponing are meeting scheduled in two weeks for another time. The prime minister was able to save a great deal of expense and effort for both for both the united states and denmark by being so direct. I thank you for that. Look forward to rescheduling sometime in the future. He is trying to punish the prime minister of denmark for deigning to take his desire to buy greenland seriously and then saying not for sale. That's how you make a deal. I guess he thinks there is a constituency in the united states that that is saying like the greenlanders wanna see him tough with the prime minister of denmark. I mean this is just bad. Crap crazy easy unless he's just like didn't wanna go or something or having a bad hair week or something like that. I'm not sure i'm not being facetious. I this is it's almost inexplicable. I i read it as he just doesn't want to go in this looking for an excuse that that's what it could be sell us french antiga. Here's is out danish prime minister. If you want to respond yeah here's her response to this now. Isn't she. Like anti immigration a little bit yeah. I think she's dreaming. Go yeah and so you you would think natural allies but i want greenland. It is with a regret and surprise that i received the news that president trump has has cancelled his state visit to denmark on the second and third as i had been looking forward to this hour preparations were well well underway. It was an opportunity. I think to celebrate then max close raisins to to u._s. And and who remains one of them much closest allies. I was looking forward to having dialogue on the menu. Shit interest denmark <hes> sh- has with views furthermore <hes> the developments in the arctic region call for further cooperation between being the u._s. and greenland faroe islands and denmark and therefore i would like to underline our invitation for stronger go corporation on arctic f s still stands at what a bad accent.
