CAMBRIDGE, MASSACHUSETTS--Top climate scientists have cautiously endorsed the need to study schemes to reverse global warming that involve directly tinkering with Earth's climate. Their position on geoengineering, which will likely be controversial, was staked out at an invitation-only meeting that ended here today. It's based on a growing concern about the rapid pace of global change and continued anthropogenic emissions of greenhouse gases.
"In this room, we've reached a remarkable consensus that there should be research on this," said climate modeler Chris Bretherton of the University of Washington, Seattle, during a morning session today. Phil Rasch, a modeler with the University Corporation for Atmospheric Research in Boulder, Colorado, underscored the point. "We're not saying that there should be geoengineering, we're saying there should be research regarding geoengineering." No formal statement was released at the meeting, which was organized by Harvard University and the University of Calgary, but few of the 50 scientists objected to the idea.
The field of geoengineering has long been big on ideas but short on respect. Some of the approaches that researchers have dreamed up include launching fleets of space-based shades to dim the sunlight hitting Earth or altering the albedo of the ocean with light-colored reflectors. Perhaps the best-known idea is to pump aerosols into the stratosphere to mimic the cooling effect of volcanoes. But there's been scant support from mainstream scientists, many of whom fear that even mentioning the g-word could derail discussion of carbon-emissions cuts. Others worry that technological tinkering might backfire. "I just accepted on faith as an environmental scientist that this had to be a bad idea," said Harvard's Scot Martin, who said he was reluctantly coming around.
