Climate Change Myths and Facts

There is a great article in the WaPost by Chris Mooney author of the book The Republican War on Science about some of the misleading arguments made by the conservative columnist George Will in his recent editorial about climate change.

Consider a few of Will’s claims from his Feb. 15 column, “Dark Green Doomsayers“: In a long paragraph quoting press sources from the 1970s, Will suggested that widespread scientific agreement existed at the time that the world faced potentially catastrophic cooling. Today, most climate scientists and climate journalists consider this a timeworn myth. Just last year, the Bulletin of the American Meteorological Society published a peer-reviewed study examining media coverage at the time and the contemporary scientific literature. While some media accounts did hype a cooling scare, others suggested more reasons to be concerned about warming. As for the published science? Reviewing studies between 1965 and 1979, the authors found that “emphasis on greenhouse warming dominated the scientific literature even then.”

Chris also addressed the common tactic of climate change skeptics to conflate climate and weather and cherry pick short term trends that agree with their points.

Will also wrote that “according to the U.N. World Meteorological Organization, there has been no recorded global warming for more than a decade.” … Will probably meant that since 1998 was the warmest year on record according to the WMO — NASA, in contrast, believes that that honor goes to 2005 — we haven’t had any global warming since. Yet such sleight of hand would lead to the conclusion that “global cooling” sets in immediately after every new record temperature year, no matter how frequently those hot years arrive or the hotness of the years surrounding them. Climate scientists, knowing that any single year may trend warmer or cooler for a variety of reasons — 1998, for instance, featured an extremely strong El Niño — study globally averaged temperatures over time. To them, it’s far more relevant that out of the 10 warmest years on record, at least seven have occurred in the 2000s — again, according to the WMO.
