"It is unequivocal that human influence has warmed the atmosphere, ocean and land. The scale of recent changes are unprecedented over many centuries to many thousands of years. Human-induced climate change is already affecting many weather and climate extremes in every region across the globe."
These words of warning, read by today's guest on Sea Change Radio, Professor Bill Moomaw, are from the most recent report by the Intergovernmental Panel on Climate Change (IPCC). This week we speak with Dr. Moomaw, a climate scientist and longtime faculty member at the Fletcher School at Tufts University, about the inner workings of the IPCC, on which he has served for many years. We talk about barriers preventing more expeditious responses to the looming threat of climate change, examine the flaws in some quick-fix proposals, and look at realistic paths toward keeping our planet habitable for centuries to come.
