Man-Made Climate Change Helped Create Wild 2012 Weather

Man-Made Climate Change Helped Create Wild 2012 Weather says a study of a dozen of 2012’s wildest weather events, reports Seth Borenstein at the Associated Press. It found that man-made global warming increased the likelihood of about half of them, including Superstorm Sandy’s devastating surge and shrinking Arctic sea ice. This is the second year that NOAA and the British meteorology office have teamed up to look at the greenhouse gas connection to the previous year’s unusual events. “We’ve got some new evidence that human influence has changed the risk and has changed it enough that we can detect it,” study lead author Peter Stott said. Scientists conducted thousands of runs of different computer simulations that looked at various factors, such as moisture in the air, atmospheric flow, and sea temperature and level. The researchers said climate change had made the following 2012 events more likely: U.S. heat waves, Superstorm Sandy flooding, the changing Arctic sea ice, drought in Europe’s Iberian peninsula (that is, Spain and Portugal), and extreme rainfall in Australia and New Zealand.

 

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: http://signon.org/sign/we-are-the-clean-99?source=c.em.cp&r_by=487176 . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
