49:1 Is Not 50:50

Forty-Nine to One is not Fifty-Fifty.   Climate change denialists like to spread it on thick and claim there's some fierce debate over the reality of anthropogenic global warming and there are a good many disinformed, misinformed and simply delusional types who think there is no consensus and it's a toss up.

That's simply garbage served up by people who manufacture garbage for people willing to consume garbage.

Yet another peer-reviewed study into the great body of climate change research studies finds 97.1% endorse the consensus view while a miserably underwhelming 1.9% reject the consensus.

That is the finding of a University of Queensland-led study that surveyed the abstracts of almost 12,000 scientific papers from 1991-2011 and claims to be the largest peer-reviewed study of its kind.

 

The report's lead author, John Cook, a fellow at the University of Queensland's Global Change Institute and founder of the website skepticalscience.com, said the scientific consensus was overwhelming, growing and had been around since the early 1990s.

 

He said that while the number of papers rejecting the consensus was "vanishingly small", his research suggested the public was under the impression the debate was split 50-50.

"When people think scientists agree, they are more likely to support a carbon tax or general climate action," he said.

"But if they think scientists are still arguing about it, they don't want to do anything about it." Carbon dioxide levels in the atmosphere are about 400 parts per million and rising – the highest in more than 3 million years.

Mr Cook said scientists now found less need to state their position on climate change in abstracts summarising their papers, "just as geographers find no reason to remind readers that the earth is round".

Science is a discipline that is not quick to embrace consensus which is one reason even phenomenon such as gravity are still treated as theories.  Therefore, when you hit 97% agreement, you truly are ringing all the bells.
