Human role in climate change now virtually certain: leaked IPCC report
Professor Stephan Lewandowsky, a researcher of climate change denial at the Cognitive Science Laboratories at the University of Western Australia, said the premature leak of the report was “dishonourable.”Stephan Lewandowsky
“Science is one of the most transparent endeavours humans have ever developed. However, for the transparency to be effective, preliminary documents ought to remain confidential until they have been improved and checked through peer review,” he said in an emailed comment.
“The leak of a draft report by a reviewer who has signed a statement of confidentiality is therefore regrettable and dishonourable.”
“However, what is worse than the leak itself is the distortion of the content of the draft chapter by some deniers (no, they are not skeptics),” he said.
Prof Lewandowsky said that the report’s statement that humans have caused global warming was a “virtual certainty” meant it’s authors had 99% confidence in that view.
“That’s up from ‘very high confidence’ (90% certain) in the last report published in 2007,” he said. [Hey Stephan: How, specifically, were those 90% and 99% numbers calculated? What, specifically, changed between 2007 and now that accounts for the alleged 90% reduction in uncertainty?]
“In other words, the scientific case has become even stronger and has now reached a level of confidence that is parallelled only by our confidence in some very basic laws of physics, such as gravity or thermodynamics.”
To claim otherwise by cherry-picking part of a sentence out of context is absurd, he said.
“Although it illustrates the standard approach by which climate deniers seek to confuse the public. Climate denial lost intellectual respectability decades ago, and all that deniers have left now is to misrepresent, distort, or malign the science and the scientific process.”
For the last few years, my new passion has been rock climbing...Most airlines [Wait, with the fate of my grandchildren allegedly hanging in the balance, this guy still takes unnecessary fuel-guzzling trips to climb on rocks?!] can handle that, whereas few take sailplanes as check-in luggage
