Seeing is believing

After the most recent spate of tropical storms out of the Atlantic, a new poll by Associated Press-NORC Center for Public Affairs Research finds that 68% of Americans think weather disasters seem to be worsening.  Moreover, almost all of this 68% attribute this increase in extreme weather events totally or mostly (46%) to human-induced climate change or at least in combination (39%) with natural variability.  According to the National Oceanic and Atmospheric Administration (NOAA), the US has experienced 15 weather disasters that cost $1 billion or more. The Associated Press’s analysis of 167 years of federal storm data concludes that “no 30-year period in history has seen this many major hurricanes, this many days of those storms spinning in the Atlantic, or this much overall energy generated by those powerful storms.” Having experienced the recent storms first-hand, Greg Thompson, a retired pest control researcher in New Orleans, sees it this way: “When so many things are happening and so many of them (storms) are intense and so many of them are once-in-500-year levels and they’re all occurring, it’s a pretty good sign global warming is having an effect.”
