Most Americans say climate change is happening and believe it contributes at least some to many extreme weather conditions seen around the world, such as melting ice in the Arctic, rising sea levels, warmer summers, droughts and forest fires.

But Americans' opinions on how much climate change contributes are marked by political differences. Most Democrats think climate change contributes a lot to each of these situations, while Republicans are more likely to say it only contributes somewhat, if at all.

Many Americans have experienced some of these weather events in recent years. Most say they have experienced unseasonable temperatures (62%), while nearly half have experienced flooding (45%) or droughts (41%). Over a quarter have experienced forest fires (29%) or a severe hurricane (27%).
