Malcolm Hughes was a participant or observer in the following events:
Nature publishes a study by climate scientists Raymond Bradley, Michael Mann, and Malcolm Hughes concluding that the last few decades were warmer than any comparable time period in the last 1,000 years. Their study shows that the pace of warming was most dramatic during the last century. The authors identified the increase of greenhouse gases in the atmosphere as the dominant factor in the observed increase in global temperatures.

Joe Barton, the chairman of the House of Representatives committee on energy and commerce, begins an inquiry into the careers of climate scientists Michael Mann, Raymond Bradley, and Malcolm Hughes. The three scientists had published a study in 1998 (see April 23, 1998) concluding that the last few decades were warmer than any other comparable time in the last 1000 years. Barton’s investigation is spurred by a recent report in the Wall Street Journal reporting that an economist and a statistician, neither of whom have a background in climate science, have found that the study was flawed. Barton’s investigation is demanding that the three scientists provide the committee with details about their funding sources, methodology, and other studies they have published. Barton, who has close ties to the fossil-fuel lobby, “has spent his 11 years as chairman opposing every piece of legislation designed to combat climate change,” notes the Guardian of London. Responding to Barton’s actions, 18 of the country’s most influential scientists from Princeton and Harvard write in a letter: “Requests to provide all working materials related to hundreds of publications stretching back decades can be seen as intimidation—intentional or not—and thereby risks compromising the independence of scientific opinion that is vital to the pre-eminence of American science as well as to the flow of objective science to the government.” Barton’s investigation also draws criticism from within his own party. Sherwood Boehlert, the chairman of the house science committee, says she objects to what she sees as a “misguided and illegitimate investigation.” [USA Today, 7/18/2005; Guardian, 8/30/2005] Congress eventually asks the National Academy of Sciences to review the issue. A year later, the Academy will publish a report confirming that the last few decades have been hotter than any other period since 1600. However, it says there is not enough data to make a solid conclusion regarding temperatures before that time (see June 22, 2006). [San Francisco Chronicle, 6/23/2006]
