AN ANTONIO - Joe D'Aleo was a rare voice of dissent this week at the American Meteorological Society's annual meeting in San Antonio. D'Aleo, executive director of the International Climate and Environmental Change Assessment Project, a group of scientists, doesn't think greenhouse gas emissions are the major cause of global warming and climate change.
Researchers who hold such contrary views do not appreciate being lumped together with flat-Earthers. They are legitimate scientists who question the mainstream, but they are a distinct minority. Greenhouse warming is real, but I think it is a relatively minor player," D'Aleo said. He claims other factors like solar activity and other natural causes are probably playing a greater role in rising temperatures -- a position that gets a mostly chilly reception from this crowd.
Several scientists and writers interviewed at the society's conference, which ends on Thursday, stressed that most researchers believe there is little scientific debate about the causes of global warming.

"I think there is largely agreement on the fact that over the last 30 years, that much of that warming has been attributed to human activities, in other words, greenhouse gas emissions," said Tony Socci, a American Meteorological Society senior science fellow. He said those who denied the connection were either "badly informed as to the scientific center or consensus, or in some cases perhaps (they are) just not wanting to be informed."
