Climate change views swayed by weather

Independent voters shift their views on climate change with the weather, new research suggests.

During cold snaps, Independents tend to be more skeptical of human-caused global warming than they are on unseasonably warm days, which seem to make them believers, according to a study published in the journal Weather, Climate, and Society. Democrats and Republicans stuck to their climate-change beliefs regardless of short-term weather changes.

"Independent voters were less likely to believe that climate change was caused by humans on unseasonably cool days, and more likely to believe that climate change was caused by humans on unseasonably warm days," said study author Lawrence Hamilton, a sociologist at the University of New Hampshire, in a statement.

      As the bitter cold in the northeastern United States keeps even hardy New Hampshire skiers off the slopes, there?s at least one potential upside to the cold snap: fewer mosquitoes come summer, according to an entomologist riding out the cold in upstate New York.

Previous studies have also shown that global warming belief depends on weather.

To see if there was a connection, the team looked 10 random-sample phone surveys conducted by the Granite State Poll between 2010 and 2012, with a total of 5,000 New Hampshire voters. The phone interviews asked respondents to choose between three options: climate change is happening now, caused mainly by humans; climate change is not happening; or it is happening, but mostly due to natural causes.

They then correlated the dates of those phone calls with temperature and precipitation data drawn from the U.S. Historical Climatology Network.?

While Republicans and Democrats stuck to their views, self-identified Independents shifted their views with the weather.

"The shift was dramatic. On the coolest days, belief in human-caused climate change dropped below 40 percent among Independents. On the hottest days, it increased above 70 percent," Hamilton said in a statement.

Though it may be human nature to tie weather to climate change, that isn't scientific. An individual storm or warm front can't be attributed to climate change, because weather patterns happen over short time periods, while climate change is a long-term trend. On average, climate change may bring more extreme weather.
