Some of you may have heard about the “ICCC-6” conference, sponsored by the so-called “Heartland Institute,” that will take place this Thursday and part of Friday in Washington D.C. It’s the best-known meeting of those who call themselves “skeptics” about global warming.
I suspect they’re not really skeptics at all. Why do I think that, you wonder? Can we talk?.
Many of us have seen graphs of the dramatic decline of Arctic sea ice over the last 30+ years (since we’ve been monitoring it via satellites), a decline which is unmatched for at least a century and almost certainly for several thousand years. The graph of sea ice extent anomaly (monthly average data from the National Snow and Ice Data Center) shows the change plainly:
From time to time we hear the claim that volcanoes inject more CO2 into the atmosphere than human activity. Its typical form is exemplified by a comment at RealClimate which was (quite appropriately) consigned to the “Borehole.”
When the volcano, Mt Pinatubo, erupted in the Philippines in 1991, it spewed out more greenhouse gases into the atmosphere than the entire human race had emitted in its entire YEARS on earth.
This claim is almost as ubiquitous as it is ridiculous, and seems to be championed by Australian geologist Ian Plimer, author of the execrable book “Heaven and Earth: Global Warming, the Missing Science.” Science seems to be missing from all of Plimer’s musings on global warming.
There’s yet another mathturbation post at WUWT. This one, by Andy Edmonds, argues that because weather is chaotic (in the mathematical sense), it’s impossible to model climate. In fact that’s the whole argument — a lot of words, but it boils down to nothing more.
Last week, a headline in the Bangor Daily News read: “Heat grips much of US, so get used to it.” It was for a story from AP about the unusual early-June heat wave which afflicted much of the U.S., and includes the report that “A new study from Stanford University says global climate change will lead permanently to unusually hot summers in the coming years.”
