Polls reveal widespread personal impact and demand for action on climate change.

A new poll by the Associated Press-NORC Center for Public Affairs Research has found that 71% of US adults have been personally affected by extreme weather in the last five years, with the majority citing extreme hot weather or heat waves and severe cold weather or winter storms. Of those affected, 69% believe climate change was to blame. The poll also found that 71% of respondents believe climate change is happening, with 63% believing it is being entirely or mostly caused by human activities. The US faced 18 climate and weather disasters that cost at least $1bn last year.
