Does global warming increase the risk of extreme weather?
Environmentalists and scientists are re-examining that possible link in light of the wild weather the United States has seen so far in 2011, including heat waves, tornadoes, and wildfires. A similar debate was prompted last year by extreme weather throughout the world, including wildfires in Russia and floods in Pakistan.
When considered collectively, what do these extreme weather events mean for the climate change debate? Should scientists study these connections further - examining, for example, whether tornadoes are linked to climate change? How could this debate affect the arguments put forth by skeptics that global warming is not occurring?
