Americans Attribute Warm Winter Weather to Climate Change

WASHINGTON, D.C. -- A majority of Americans, 63%, say the weather in their local area this winter was warmer than usual. When asked what they think caused these abnormal temperatures, more Americans say the shift was the result of human-caused climate change rather than normal variations. Just 10% of Americans say it was a colder winter than usual, and 26% say the weather was about the same.

Most recently, Americans who have said they've experienced abnormal winter temperatures have been more likely to attribute those changes to normal variations than to climate change. The shift this year is likely because a larger, more regionally and politically diverse group of Americans is reporting warmer temperatures this year.

Majorities of Americans of all political identities say this winter was warmer than usual. However, more Democrats (76%) than Republicans (51%) say this, and Democrats who say it was warmer are more than twice as likely as Republicans to attribute the rise in temperatures to climate change, as Gallup has found in the past.

Gallup's annual March Environment poll has asked Americans since 2012 to report on weather conditions in their local areas. Americans appear to be reasonably accurate in their temperature assessments. This year and in 2012, majorities have said it was warmer than usual. This year's poll was conducted just before warm, spring-like temperatures came early for much of the U.S. East Coast but a few weeks after summer-like temperatures in California and much of the Southwestern region. El Nino is probably one cause of this abnormal weather.

In 2014 and 2015, Americans were most likely to say the weather was colder than usual, an assessment generally in line with official statistics.

The highest proportions of adults saying it was warmer than usual this winter -- more than seven in 10 -- were in the East and Midwest, the regions most likely to experience cold winters. But even a majority of Southerners reported warmer-than-normal temperatures. Americans in the West were the least likely of all four regions to say the winter was warmer than usual; still, 49% said this.

	East%	Midwest%	South%	West%
Colder	5	6	11	19
About the same	17	21	31	31
Warmer	78	72	57	49

Last year, Americans' views of their winter weather varied more by region. Westerners were more likely to say it was warmer rather than colder, and their responses were the most similar to this year's. In the other regions, especially the East, residents were more likely to say it was colder than usual last year. This again largely matched the varying weather patterns found in different parts of the country last winter.

Bottom Line

Scientists say 2015 was the warmest year on record across the globe, and temperatures increased by one of the largest amounts found since record keeping began in 1880. U.S. temperatures were also high, and that trend appears to have continued this winter, as El Nino has affected the weather. And, while scientists say climate change is driving global temperatures up, they say the more recent changes also reflect a spike in the usual patterns. Still, Americans were more likely this year to attribute the extreme weather to climate change rather than normal variations, including El Nino.

Cold weather was partially to blame for low U.S. gross domestic product figures in the first quarter of last year, because snow and cold temperatures discourage shopping and traveling and encourage people to bundle up at home, not spending money. But in the late 1990s, an El Nino event boosted GDP by at least a small amount, something that could happen again this year. So the warm weather Americans have reported this winter could be a good sign for the GDP in the first quarter, even if it means fewer people buying snow shovels and salt for sidewalks and driveways over the past few months.

Survey Methods

Results for this Gallup poll are based on telephone interviews conducted March 2-6, 2016, on the Gallup U.S. Daily survey, with a random sample of 1,019 adults, aged 18 and older, living in all 50 U.S. states and the District of Columbia. For results based on the total sample of national adults, the margin of sampling error is ±4 percentage points at the 95% confidence level. All reported margins of sampling error include computed design effects for weighting.

Each sample of national adults includes a minimum quota of 60% cellphone respondents and 40% landline respondents, with additional minimum quotas by time zone within region. Landline and cellular telephone numbers are selected using random-digit-dial methods.
