Michael MacCracken is chief scientist for climate change programs at the Climate Institute. He discusses important new findings of the recent United Nations Environmental Programme (UNEP) report, which illustrates how climate change is occurring faster and on a larger scale than predicted by the Intergovernmental Panel on Climate Change (IPCC) in 2007. The most dramatic example is how sea ice is melting much more rapidly than initially projected. The report suggests that sea levels will rise an additional three feet due to melt from Greenland and Antarctica. On another, more positive front, MacCracken remarks that China has been successful in cleaning the quality of their air. The pollution there today is not nearly as bad as it was five years ago. The Chinese are taking major actions to reduce their CO2 emissions by driving more efficient vehicles and improving their industry emissions, thus minimizing not only pollution but adverse health effects.moreless
