Record warm temperatures throughout mid-March have had at least one predictable outcome: the global warming alarmism is back in fashion this Spring. Despite the fact that even advocates of the theory are only willing to say that manmade climate change "likely contributed on the order of 5% to 10% of the magnitude of the heat wave during 12-23 March," this fact is being kept far from the headlines.
An article by Andrew Freedman for climatecentral.org (“Global Warming May Have Fueled March Heat Wave Odds”) gives a sense of the tenuous nature of the claims by the theory’s advocates:
According to several top scientists, the March heat wave that has shattered records across a wide swath of the U.S. bears some of the hallmarks of global warming.
In email conversations on Wednesday and Thursday, those same scientific researchers who specialize in studying the role climate change plays in influencing individual extreme events — a burgeoning field known as "extreme event attribution” — said global warming may have made March's soaring temperatures more likely to occur, although they add that natural variability has played a key role as well.
In fact, attempts to link the warm days of March to theories of global catastrophe are being couched more carefully than the environmental jeremiads of a few years ago — apparently advocates of the global warming theory have not forgotten the debacle of the UN “global warming” conference several years ago in Copenhagen, when world leaders were greeted by temperatures more befitting a new ice age. The brashness of old forecast of the effects of global warming have been replaced by guarded discussions of “influence.” Thus, Freedman notes:
