"Global warming strikes America! Brrrr!" So tweeted Missouri Representative Vicky Hartzler last week, as much of the U.S. experienced extreme cold. (In Buffalo, it was a full Snowpocalypse.) Do frigid temperatures give you doubts about global warming?

You wouldn't be alone. When people think the day's weather is exceptionally cold, research shows, they're less likely to be concerned about global warming. And when the day seems unusually hot, concern jumps.

Notably, this effect can be found among Republicans and Democrats, men and women, young and old. Strange but true: As the question of climate change receives sustained attention in Washington in the coming months, public opinion is likely to be affected by short-term swings in the weather.
