United Nations, Paris, KIM discussed on Here & Now

Here & Now


State University thank you so much for joining us, Ain't you? When world leaders to combat climate change in Paris back in two thousand fifteen, they agreed to cap global warming at one and a half. Degrees Celsius over pre industrial levels to avoid the disastrous effects of a hotter planet. Well now, the United Nations says we crossed that. That threshold in the next five years, let's bring in Kim. Cobb climate, scientist and professor at the Georgia Institute of Technology Kim Welcome. Thanks for having me. Yesterday's forecast is from the UN's World Meteorological Organization. It says there's a twenty percent chance that we'll see a temperature increase of at least one and a half degrees Celsius in one of the next five years. How significant is that information? Well, it's very significant of course, and this is just part of. Growing warming that has been occurring for decades now, and there's no reason for us to expect it to stop, but of course that one point five degrees Celsius marker is a line that was drawn in the sand at the United Nations level in two, thousand, fifteen, marking what was plausible at the time avoiding future warming rates, but also noting that beyond one point five, embracing a fairly large pile of risk, some of which we don't understand very well, so kind of bumping up against that threshold is really alarming, and of course expect across that in the very near future. What do you mean by large risk that we don't understand well well? Well we know that continued warming will bring some certain ts to us. rising seas, drier regions like California getting drier, more, wildfire, prone, and some of those wetter areas, being more susceptible to extreme precipitation, none of which is welcome, but some of the most scary kind of impacts longer term have to do with potential accelerations in the kind of climate impacts that we could be bringing to our doorstep. Things that are kind of the surprises we might see including real acceleration in a system that we of course would be unprepared for one and a half degrees Celsius was the threshold as we said that Paris, said in two thousand fifteen. Does. This data suggests that the pact just isn't working well. Obviously, we are letting one point five degrees. Celsius slip through our fingers. Despite the fact that as part of the one point five degree target, there was an entire report that provides a roadmap to bring that into reality, fantastic detail and also outlining. What's at risk if we set a new target for? For two degrees. Let's say the next round number if you will be on one point five, and that is what is most alarming is from a scientific perspective. We have the data. We have the knowledge and yes. We have not acted upon it. So what would we have to do in order to make sure that it doesn't slip through our fingers.
