Report Summary
Our latest national survey finds that a large majority of Americans think global warming is happening, outnumbering those who don’t by more than 5 to 1. Americans are also growing more certain that global warming is happening and more aware that it is caused by human activities. Certainty has increased 14 percentage points since March 2015, with 51% of the public now “extremely” or “very sure” that global warming is happening. Sixty-two percent of the public now understands that global warming is caused mostly by human activities, an increase of 10 points over that same time period.
