When sea ice melts, it can lead to faster warming because water absorbs more heat than ice does. That’s one of more than 25 climate feedback loops found in a recent study from Oregon State University. Some of these feedback loops aren’t included in current climate models, partly because the science, and the climate, is changing so quickly. Jillian Gregg, co-author of the new report, joins us to explain what we should understand about feedback loops.
