At the risk of fuelling up John Quiggin and UnAustralian Ken Miles (though only with renewable energy resources), here’s a fascinating post on Aaron Oakley’s Bizarre Science summarising new research suggesting that much of the observed 20th century global warming is actually caused by variations in the activity of supernovae (rather than carbon dioxide generated by evil western capitalists).
The author of
the study (and Oakley’s post) is Tim Patterson, a professor in the department of earth sciences at Ottawa’s Carleton University, who specializes in paleoclimatology (whatever that is). The paper is published by the Geological Society of America, and appears to be refereed.
Update – The UnAustralian Ken Miles has an excellent long analysis in the comment box to this item, and is apparently about to post an even more extended version on his own blog. Gummo Trotsky has also posted an excellent long analysis (but his permalinks are bloggered as usual). I’m often amused by the way self-consciously provocative posts seem to be far more successful than worthy and balanced analyses at eliciting responses, especially from thoughtful bloggers. It’s one reason why Bunyip and Blair fill such a valuable blogosphere role. Shit-stirrers rule!
