More than half of Americans think global warming is affecting weather in the United States, according to a new nationally representative survey that measures the pulse of American sentiment on climate change.
The newly released study shows that about two out of three Americans say weather in the country has worsened over the past several years, with only one in 10 saying the weather has been improving.
Americans also have strong views about the link between global warming and extreme weather.
