"Temperature changes responding to that. We put the earth warmer than it has been in in millions of years. So so saying what exactly the impact of that would be on? You know, the the corn harvest in Iowa or or something like that is is really not a very easy thing to do with respect to Seattle. The question is all how quickly can the nature ice sheets respond to the changes in climate the models that have been developed in the past. Don't respond nearly as as strongly has the observations that theologist actually can make in Greenland and Antarctica about how the high streams flowing into the ocean respond to the changes in climate, you you can measure more ice quakes in Greenland with seismometers, then you could five years ago and ice sheets that ice streams flowing from the ice sheets into the ocean are exceleron. So it's really kind of anybody's guess how long it takes for sea to change. There were a events in the past called Heinrich events when the Lauren tied icesheet, which is in was in North America. Every eight thousand years or so during the last ice age, which just collapse into the ocean, and there'd be this armada of icebergs in the North Atlantic, and they would carry little rocks and sand and stuff like that. That would then deposit on the sea floor, and there's no way for those to get their other than these ice, icebergs. And so that's how we know about these events today is by finding those layers of rocks on the bottom of the Atlantic. Those seemed like they took a century or a few centuries, and they seem some of them to have raised T level by many meters, which is much more than any of the ice sheet models predict for. The global warming climate event. But I think a lot of people everybody thinks most everybody thinks that these icesheet models are just lacking some essential physics at this point. While some people say that the real problem with sea level rise is simply the thermal expansion of ocean water with the rising temperature of the earth and says the earth is rising in temperature. The oceans are going to expand no matter what happens to the North Pole of the south pole. That's absolutely true. And that's part of the the forecast for sea level rise by the year twenty one hundred which is about a half a meter or so something like half of that sea level rise is caused by exactly this affect the expansion of the sea water. It's like the mercury in the thermometer. Tolls. Up more the thermometer when the temperature goes up that's a process that will keep going for centuries. So the forecast for the year twenty one hundred is not sort of the end of the line. That's just the beginning for the thermal expansion of water the other half of the sea level rise. That's actually in the. IPCC forecast for the year. Twenty one hundred is melting of of smaller mountain glaciers like in the handy's and the helps and actually a lot of them. A lot of the sea level rise today can be attributed to mountain glaciers in the state of Alaska. It just happens to be a place where there's lots of ice frozen on mountains. And where the climate changes are very intense, but it's some astonishingly large fraction of level rise from Alaska. Okay curiosity. Okay. So what does that mean for the average person who has to make decisions enormous decisions in the next few years about fossil fuel consumption by an investment in solar energy, and so on and so forth. What changes in their lifestyle? Should we expect in the coming decades? Well, you know device styles could change because we adapt to new energy technologies. One of the most of the. CO two emissions that can be avoided in the next few decades, actually, come from improvements in officiency. Well, unfortunately, that's it for exploration. Once again, we had to special guests today. The first special guest was Dr Peter ward, author of the book flooded earth. And the second guest was Dr David Archer, author of the book the long haul and this is exploration with Dr Michio Kaku..

"I'd like to introduce our special guests for today. He's professor David Archer, professor a geophysical sciences at the university of Chicago anythi, author of a rather disturbing. New book is called the long far how humans are changing the next one hundred thousand years of earth's climate. He argues in the long Faulk that not only are humans ruining the atmosphere of the earth by dumping copious quantities of carbon dioxide, but the effects of this will linger in the atmosphere, not just for years, not just for centuries, but one hundred thousand years, and what does it mean? What does it mean for us to live in a world with that much carbon dioxide and that much global warming? Once again, the special guest is Dr David Archer of the university of Chicago. The book is called the long thought. Professor Archer as a youth. How did you first get interested in science and in particular earth science, I guess they look to the cursed. The functioning of the earth is stable geochemical cycles of things like that. That's bigger than than people. Are I look to the natural world sort of reverence? I think that's what brought me into the natural sciences. Why I chose to study the oceans actually instead of force or other planets or stars or something like that. Because I've always had a romantic love of boats but nine ended up living in Chicago anyway. But that's just one of the jokes. I guess. Okay. Well, let's get right into it. First of all, what is the relationship between carbon dioxide and global warming. Carbon dioxide traps infrared light that tries to leave the atmosphere. It's like if you put a coat on in the wintertime it did traps the heat leaving your body. So it allows your body to to to warm up theory about CO two how it affects the climate of the earth, and how much it affects the climate of the earth is over one hundred years old now, it's very very solid science. But there were no greenhouse effect. We wouldn't be able to explain why the earth isn't in a d pres or the climate of Venus or or lots of other things at the very solid, and we'll talk about Venus, some people call Venus, the greenhouse planet..
