Climate sensitivity is a measure of how sensitive the model is. It used to be one and a half to four and a half degrees, if you doubled c o two. The latest estimates now are two and ahalf to four. So it's not quite as a sensitive a it may not be quite as sensitive as we thought. But also a little bit more raised on the low end.
According to Steven Koonin, when it comes to climate change, the media, politicians, and other prominent voices have declared that “the science is settled.” Koonin avers that the long game of telephone from research to reports, to the popular media, is corrupted by misunderstanding and misinformation. Koonin says that core questions about the way the climate is responding to our influence, and what the impacts will be remain largely unanswered. Koonin acknowledges that the climate is changing, and he claims the whyand how aren’t as clear as you’ve probably been led to believe, and what the impacts will be remain largely unanswered.
In this engaging conversation Michael Shermer challenges Dr. Koonin with many of the most common critiques of his book, Unsettled: What Climate Science Tells Us, What It Doesn’t, and Why It Matters, and Steven Koonin responds by drawing upon his decades of experience — including as a top science advisor to the Obama administration.
