Climate Deniers Get a Reality Check

In what should, in a rational world, have been an entirely unnecessary research project, US scientists have once again explored familiar ground and arrived at a familiar conclusion:  97% of climate scientists agree that climate change is happening − and that it is caused by humans.
Sarah Green, a chemistry professor at Michigan Technological University and one of the report’s co-authors, adds: “What’s important is that this is not just one study − it’s the consensus of multiple studies.”
Levels of expertise
In the latest study, the researchers once again concluded that the greater the levels of expertise in climate science among those quizzed, the greater the likelihood of agreement that humans cause climate change.

Sources of possible confusion might include surveys of people who had already made up their minds that it isn’t happening or that it isn’t the fault of humans.  It was possible, too, that those quizzed were not themselves experts in climate science: some might be economic geologists, with expertise in coal or oil deposits.

But the outcome, after more than a quarter of a century of scientific consensus on climate change, remains the same:  only 12% of people in the US and 15% in Australia are aware that there is strong agreement among climate scientists.

“The public has a very skewed idea of how much disagreement there is in the scientific community,” Professor Green says.
