Yohe on Costs of Polar Ice Melt, Global Warming

Gary Yohe, Woodhouse/Sysco Professor of Economics and a senior member if the U.N.’s IPCC panel, discusses the economic implications of polar ice melt with ABC’s Bill Blakemore ’65. Some estimates have the costs of polar ice melts and ensuing rising seas at $2.4 trillion over the next few decades. Yohe says that there have been more than 300 studies on the dollar costs of global warming with varying outcomes projected. Yohe points out more than 88% of the studies show negative implications and heightened dollar costs over the long term.
