Our March 2018 survey finds that a large majority of Americans think global warming is happening, outnumbering those who don’t by 5 to 1. Americans are also growing more certain that global warming is happening. Certainty has increased 12 percentage points in the past 3 years, with 49% of the public now “extremely” or “very sure” that global warming is happening. The report includes many other interesting findings, including how often Americans hear and talk about global warming and the reasons why they often don’t talk about it with their family and friends.
