Climate Change:

NRDC's David Hawkins looks at the state of global warming science

Opinion polls show that the American public is increasingly concerned about climate change. But will the issue resonate with voters during the mid-term elections this fall? And are environmental groups oversimplifying the science behind global warming as they take their message to the masses? During today's OnPoint, David Hawkins, director of the climate center at the Natural Resources Defense Council, discusses growing awareness of the issue and the challenges facing policymakers. He also talks about NRDC's position on coal gasification, and the potential for new technology to reduce greenhouse gas emissions.
