The Times has a nice article on global warming and the “availability entrepreneurs;” activists, journalists and publicity-savvy scientists who selectively monitor the globe looking for newsworthy evidence of a new form of sinfulness, burning fossil fuels. This group has started an “availability cascade,” a self-perpetuating process: the more attention a danger gets, the more worried people become, leading to more news coverage and more fear.
From the article:
A year ago, British meteorologists made headlines predicting that the buildup of greenhouse gases would help make 2007 the hottest year on record. At year’s end, global temperature average was actually lower than any year since 2001; little news coverage.
When the Arctic sea ice last year hit the lowest level ever, it was big news and heralded as a sign that the whole planet was warming. Meanwhile, a large part of Antarctica has been cooling, but that was pretty much ignored.
Hurricane Katrina was supposed to be a harbinger of the stormier world predicted by some climate modelers. When the next two hurricane seasons were the calmest in three decades, the availability entrepreneurs changed the subject. Droughts in California and Australia became the new harbingers of climate change (never mind that a warmer planet is projected to have more, not less, precipitation over all).
In his Nobel Prize acceptance speech, Mr. Gore didn’t dwell on the complexities of the hurricane debate, nor did he mention how calm the hurricane season had been. Instead, he alluded somewhat mysteriously to “stronger storms in the Atlantic
and Pacific.”
So, I guess the lesson is, no matter what the weather in 2008, be afraid – be very afraid…
