Even before this weekend’s unseasonable rash of tornadoes in the Midwest and South, there were indications that the strange weather of recent years had occasioned a SHIFT in Americans’ attitudes regarding global warming:
The number of people who believe that the planet is warming is at its highest level since the fall of 2009. According to a survey conducted in December 2011 by the National Survey of American Public Opinion on Climate Change, 62% of Americans say they think global warming is happening. That’s up 7% from last spring.
That matches other recent public opinion research Climate Progress has reported on.
With record-shattering droughts, floods and storms in 2011 that scientists attribute to an increasing degree to warming, atmospheric circulation changes, and extra moisture in the atmosphere driven by greenhouse gas emissions, and with 4 out of 5 Americans impacted by extreme weather since 2006, more people say that temperatures and weather changes are influencing their perception of global warming.
