One-Third in U.S. Blame Unusual Winter Temps on Climate Change

One-Third in U.S. Blame Unusual Winter Temps on Climate Change

Story Highlights

  • By 43% to 20%, more in the U.S. experienced a colder than warmer winter
  • 70% now blame human activity for warmer winter, up from 38% in 2012
  • Fewer blame human activity for unusually cold temperatures

WASHINGTON, D.C. -- As the winter of 2018-2019 entered its final phase in early March, 43% of Americans told Gallup their local temperatures have been colder than usual this winter while about half as many, 20%, reported warmer than usual temperatures. Overall, a third of Americans this year attributed atypical winter weather to human-induced climate change.

Americans' Perceptions About Temperatures This Winter Where They Live
Next, I'd like you to think about the weather in your local area this winter season compared to past winters. Have temperatures in your local area been -- [colder than usual this winter, about the same (or) warmer than usual this winter]? Do you think temperatures are (colder/warmer) mainly due to [human-caused climate change (or to) normal year-to-year variation in temperatures]?

Gallup

These results are based on Gallup's March 1-10 Environment poll, conducted prior to the recent bomb cyclone that brought blizzard and hurricane conditions to parts of the country. Respondents were first asked to say whether temperatures this winter where they live have been colder than usual, about the same as usual or warmer than usual. Those reporting colder or warmer than usual temperatures were then asked whether they attribute that to human-caused climate change or normal year-to-year variation in temperatures.

More Attributing Colder and Warmer Weather to Climate Change Than in Past

Seventy percent of the subset of U.S. adults experiencing warmer temperatures this winter, and 44% of those experiencing colder than normal temperatures, attribute their atypical weather to human activity.

The percentage of Americans experiencing unusual weather that attributed it to human-induced climate change has increased fairly sharply for both temperature perceptions since Gallup began tracking this in 2012.

  • In 2012, when temperatures nationwide were 3.69 degrees higher on average than normal, 38% of those experiencing warmer than usual weather blamed it on human activity. The percentage blaming warmer weather on human activity rose into the 50s from 2013 to 2017 before rising to 70% this year.
  • The sample sizes of those experiencing colder than normal weather in 2012 and 2013 were too small to allow reporting of these respondents' views on the cause. However, in 2014, when the sample size was sufficient, just 29% thought colder-than-normal weather was due to human activity. That rose to 37% in 2015, to 40% in 2016, and has since been above 40%.

The average temperature throughout the U.S. in February this year is 32.00 degrees Fahrenheit. That is almost two degrees below the February average across the historical reference years from 1900-2000, as reported by the National Oceanic and Atmospheric Administration (NOAA). However, this masks sharp differences by region that are reflected in the Gallup data.

Close to two-thirds of residents of the Midwest and West say they've had colder than usual temperatures this winter, driving up the national percentage reporting this. That conforms with NOAA data showing these regions suffering average temperatures about five to six degrees Fahrenheit below average, historically.

At the same time, residents of the East were slightly more likely to say they experienced colder than warmer temperatures, even as they, too, enjoyed a warmer February. The views of those in the South were generally aligned with their regional temperatures, with more reporting they've had warmer than colder temperatures. Temperatures in the South ran 3.6 degrees higher than normal in February.

Regardless of their perceptions of local temperatures, about a third of residents in each of the four regions attributes the unusual winter temperatures where they live to human-induced climate change.
