Heatwave seems to make manmade climate change real for Americans

The warm temperatures that have scorched much of the US appear to be influencing Americans’ acceptance of climate science, with a new poll finding a record level of public confidence that the world is warming due to human activity.

A long-running survey of American attitudes to climate change has found that 73% of people now think there is solid evidence of global warming. A further 60% believe that this warming is due, at least in some part, to human influences.

Both of these findings are record highs in a twice-yearly survey that has been conducted by the University of Michigan and Muhlenberg College since 2008. The latest poll was conducted during May, which was hotter than any May recorded in the contiguous US in 124 years of record keeping, according to the National Ocean and Atmospheric Administration, eclipsing the 1930s during the Dust Bowl era.
