Global Warming Surveys by various online polls: 32 percent Americans fear human activity pollution

A prominent climate scientist from Penn State says more Americans than ever before believe global warming will pose a threat to their way of life.

Climate change denial is simply no longer plausible, and the American people are recognizing that," says Michael Mann, a distinguished professor of atmospheric science and director of the Earth System Science Center at Penn State.

'Human pollution has led to climatic change', a majority of voters in The Free Press unscientific online poll believe.

According to Mankato Free Press: Fifty-five percent of voters, or 150 votes, agreed that warming temperatures are due to human activity, not natural causes. But nearly a third - 32 percent, or 88 votes - blamed natural causes.

Last year was the warmest ever recorded, and four western states just had their warmest February on record, according to the National Oceanic and Atmospheric Administration. Still, several cities - including Chicago and Cleveland - observed their coldest February.

With 55 percent blaming human causes and 32 percent blaming natural ones, the final 13 percent of voters were split nearly evenly between those who weren't sure and those who said temperatures have not increased much over the past century.

If you include the latter voters - who did not, clearly, believe in man-made climate change - the percentage of global warming skeptics rises to 38 percent.

According to a Gallup survey conducted March 2-6, a record 65 percent of the public now says human activity is to blame for higher temperatures. Gallup reported a "striking" 10 percentage-point increase over the past year. The previous high of 61 percent was recorded in 2007.

While Polling firm Gallup, which has been tracking public sentiment on the topic annually since 1997, found that 41 percent of adults in the U.S. .feel warming will pose a "serious threat" to them during their lifetimes. This is the highest level recorded by Gallup, a 4 percent increase on 2015, the Guardian reported.

Will the 32 percent of human population who voted for 'human pollution' as the cause for global warming take serious measures to control it?
