Workshops) to analyze the problems and to discuss solutions. They have been held throughout the world, and are documented through the presentations. The presentations from the workshops have been made available for free via the AAPG's open access online journal, Search and Discovery. Global warming controversy In 2006, the AAPG was criticized for selecting author Michael Crichton for their Journalism Award for Jurassic Park and "for his recent science-based thriller State of Fear", in which Crichton exposed his rejection of scientific evidence for anthropogenic global warming. Daniel P. Schrag, a geochemist who directs the Harvard University Center for the Environment, called the award "a total embarrassment" that he said "reflects the politics of the oil industry and a lack of professionalism" on the association's part. The AAPG's award for journalism lauded "notable journalistic achievement, in any medium, which contributes to public understanding of geology, energy resources or the technology of oil and gas exploration." The name of the journalism award has since been changed to the "Geosciences in the Media" Award. The criticism drew attention to the AAPG's 1999 position statement formally rejecting the likelihood of human influence on recent climate. The Council of the American Quaternary Association wrote in a criticism of the award that the "AAPG stands alone among scientific societies in its denial of human-induced effects on global warming." As recently as March 2007, articles in the newsletter of the AAPG Division of Professional Affairs stated that "the data does not support human activity as the cause of global warming" and characterize the Intergovernmental Panel on Climate Change reports as "wildly distorted and politicized." 2007 AAPG revised position Acknowledging that the association's previous policy statement on Climate Change was "not supported by a significant number of our members and prospective members", AAPG's formal stance was reviewed and changed in July 2007. The new statement formally accepts human activity as at least one contributor to carbon dioxide increase, but does not confirm its link to climate change, saying its members are "divided on the degree of influence that anthropogenic CO2 has" on climate. AAPG also stated support for "research to narrow probabilistic ranges on the effect of anthropogenic CO2 on global climate." AAPG also withdrew its earlier criticism of other scientific organizations and research stating, "Certain climate simulation models predict that the warming trend will continue, as reported through NAS, AGU, AAAS, and AMS. AAPG respects these scientific
