Does climate change seem like a distant threat we don't need to worry about now? Does it seem like an insurmountable problem we can't deal with? Please join us at 7:00pm on Thursday, April 25, to hear Dr. Steve Ghan address what climate change is, how it's affecting us already, and what we can do to mitigate it. Dr. Ghan is recently retired from Pacific Northwest National Laboratory, where he was part of the Intergovernmental Panel on Climate Change (IPCC) team that won the 2007 Nobel Peace Prize.
