Andrew Weaver on James Hansen’s latest climate study

James Hansen has a new study in the Proceedings of the National Academy of Sciences that leads him to warn that “we are wasting precious time” to act on climate change.

CBC interviews University of Victoria climate scientist Andrew Weaver about the findings:

The science in Hansen’s study is excellent “and reframes the question,” said Andrew Weaver, a climate scientist at the University of Victoria in British Columbia who was a member of the Nobel Prize-winning international panel of climate scientists that issued a series of reports on global warming.

“Rather than say, ‘Is this because of climate change?’ That’s the wrong question. What you can say is, ‘How likely is this to have occurred with the absence of global warming?’ It’s so extraordinarily unlikely that it has to be due to global warming,” Weaver said.

Interestingly, it appears the publication of Hansen’s op-ed violated an embargo placed on the story by the Proceedings of the National Academy of Sciences. Another example of how academic publishing must adjust to a faster web.
