How much of a factor is climate change in the 2012 Western US wildfires? Ask a NASA JPL scientist.

JPL Climatologist Bill Patzert, on the current wildfire outbreak in the Western United States, and the role of climate change: "What's really changed in recent years is that there are more and more people building and living at the urban/wildland interface, so the human impact is greater every time these great fires erupt (...) Looking to the future, the uncertainties of human-influenced climate change will play a stronger and stronger role, and rewrite our fiery history." More here.
