Climate scientists fighting back

WASHINGTON – Faced with increasing political attacks, hundreds of climate scientists are joining a broad campaign to push back against congressional conservatives who have threatened prominent researchers with investigations and have vowed to kill regulations to rein in human-created greenhouse gas emissions.

The efforts reveal a shift among climate scientists, many of whom have traditionally stayed out of politics and avoided the news media. Many now say they are willing to go toe-to-toe with their critics, some of whom gained new power after the Republicans won control of the House in last Tuesday’s election.

Today, the American Geophysical Union, the country’s largest association of climate scientists, plans to announce that 700 climate scientists have agreed to speak out as experts on questions about global warming and the role of man-made air pollution. Some are prepared to go before what they consider potentially hostile audiences on conservative talk-radio and television shows.

John Abraham of St. Thomas University in Minnesota, who last May wrote a widely disseminated response to climate-change skeptics, is organizing a “Climate Rapid Response Team,” which so far has more than three dozen leading scientists to defend the consensus on global warming in the scientific community. Some are also preparing a handbook on the human causes of climate change, which they plan to start sending to U.S. high schools as soon as this fall.

“This group feels strongly that science and politics can’t be divorced and that we need to take bold measures to not only communicate science but also to aggressively engage the denialists and politicians who attack climate science and its scientists,” said Scott Mandia, professor of physical sciences at Suffolk County Community College in New York.

“We are taking the fight to them because we are … tired of taking the hits. The notion that truth will prevail is not working. The truth has been out there for the past two decades, and nothing has changed.”

Prominent Republican congressmen such as Darrell Issa, R-Calif., Joe L. Barton, R-Texas, and F. James Sensenbrenner Jr., R-Wis., have pledged to investigate the Environmental Protection Agency’s regulation of greenhouse gas emissions. They say they also intend to probe the so-called Climategate scandal, in which thousands of e-mails of leading climate scientists were hacked and released to the public late last year.

Climate-change skeptics argued that the sniping in some e-mails showed that scientists suppressed research by skeptics and manipulated data. Five independent panels subsequently cleared the researchers involved and validated the science.

“People who ask and accept taxpayer dollars shouldn’t get bent out of shape when asked to account for the money,” said James M. Taylor, a senior fellow and a specialist in global warming at the conservative Heartland Institute in Chicago. “The budget is spiraling out of control while government is handing out billions of dollars in grants to climate scientists, many of whom are unabashed activists.”

Ongoing public interest in Climategate has prompted climate scientists to act.

The American Geological Union plan has attracted a large number of scientists in a short time because they were eager to address what they see as climate misinformation, said Jeffrey Taylor, research fellow at the National Center for Atmospheric Research in Colorado and manager of the project.

Still, the scope of the group’s work is limited, reflecting the ongoing reluctance by many scientists to venture into politics.

“People who’ve already dug their heels in, we’re not going to change their opinions,” Mandia said. “We’re trying to reach people who may not have an opinion or opinion based on limited information.”
