Until recently, the American Association of Petroleum Geologists was the only significant scientific organization with an official position rejecting anthropogenic global warming. Issued in 1999, it claimed that “Recently published research results do not support the supposition of an anthropogenic cause of global climate change”. AAPG has abandoned that position and issued a new position statement.
The new position statement is equivocal, beginning with the observation that “the AAPG membership is divided on the degree of influence that anthropogenic CO2 has on recent and potential global temperature increases”, and going on to say “Certain climate simulation models predict that the warming trend will continue, as reported through NAS, AGU, AAAS, and AMS. AAPG respects these scientific opinions but wants to add that the current climate warming projections could fall within well-documented natural variations in past climate and observed temperature data.”
Still, its a big advance on the embrace of delusionism that led to the 1999 statement and to the embarrassing decision in 2006 to give a science journalism award to Michael Crichton. Of course, this will have no effect on those who get their science from fiction writers, opinion columnists and rightwing thinktanks, but it’s encouraging nonetheless.
