Cuts in CO2 emissions said necessary to save world's coral reefs

WASHINGTON, June 28 (UPI) -- Deep cuts in carbon dioxide emissions are needed to stop the world's coral reefs from dying off from inhospitable ocean chemistry, U.S. researchers say.

Global warming 'solution' could backfire

PALO ALTO, Calif., June 29 (UPI) -- A cloud-seeding scheme proposed to combat global warming could change global rainfall patterns and result increased monsoonal rains, researchers say.

CO2 effects on plants hikes global warming

STANFORD, Calif., May 4 (UPI) -- U.S. biologists say trees and other plants help keep the planet cool, but rising levels of atmospheric carbon dioxide are negating that effect.

PALO ALTO, Calif., June 18 (UPI) -- U.S. scientists considering wind power tapped by high-flying kites say New York City is a prime location for exploiting high-altitude winds.

World needs CO2 emergency backup plan

LONDON, Nov. 11 (UPI) -- U.S. climate scientist Ken Caldeira of the Carnegie Institution has told the British Parliament the world needs a carbon dioxide emergency backup plan.

Acidic oceans may tangle food chain

THE DALLES, Ore., June 6 (UPI) -- Increased carbon levels in ocean water could have devastating impacts on marine life, scientists testified Thursday at a congressional hearing.

Changing jet streams may alter storm paths

STANFORD, Calif., April 17 (UPI) -- U.S. scientists say changes in the Earth's jet streams, possibly caused by global warming, might affect storm paths and intensity, including hurricanes.

Report: Drastic greenhouse cuts not enough

WASHINGTON, March 11 (UPI) -- Two studies by U.S. researchers suggest carbon emissions have to end completely within this century to avert dangerous global warming.

CO2 ocean levels could violate EPA rules

WASHINGTON, Sept. 20 (UPI) -- An international team of scientists determined ocean carbon dioxide levels might exceed U.S. Environmental Protection Agency standards by mid-century.

Study: Oceans acidify from CO2 buildup

CHAMPAIGN, Ill., March 22 (UPI) -- A U.S. study suggests ocean acidification changes from CO2 emissions are mostly independent of any temperature increase caused by the emissions.

Study: Oceans becoming more corrosive

HONOLULU, Feb. 20 (UPI) -- Earth's oceans may soon become more corrosive than they were when the dinosaurs died if the world's carbon dioxide emissions are not reduced.

Study: Forests could worsen global warming

SAN FRANCISCO, Dec. 6 (UPI) -- A study by the Carnegie Institution and U.S. government scientists says planting trees to absorb carbon dioxide may worsen global warming.

Carbon dioxide threatens world's oceans

LONDON, June 30 (UPI) -- Britain's Royal Society called Thursday on Group of Eight leaders to quickly cut carbon dioxide emissions that may make the oceans dangerously acidic by 2100.

Washington Agenda-Federal

By United Press International

Ken Caldeira is an atmospheric scientist who works at the Carnegie Institution for Science's Department of Global Ecology. He researches ocean acidification, climate effects of trees, intentional climate modification, and interactions in the global Carbon cycle/climate system.. He also acted as an inventor for Intellectual Ventures, a Seattle-based invention and patent company headed up by Nathan Myhrvold.

Caldeira's work was featured in a November 2006 article in The New Yorker, entitled "The Darkening Sea." In 2007, he contributed two op-ed pieces on the subject of global warming to The New York Times. He was named a "Hero Scientist of 2008" by New Scientist magazine.

In response to the controversy caused by Superfreakonomics over Caldeira's view on geoengineering, Caldeira rejected the suggestion that he said ″Carbon dioxide is not the right villain″. He responded by posting on his website, "Carbon dioxide is the right villain...insofar as inanimate objects can be villains." He said that while the other statements attributed to him by authors Steven Levitt and Stephen Dubner are ″based in fact″, the casual reader could come up with a misimpression of what he (Caldeira) believes.
