WASHINGTON - Climate scientist Michael Mann runs down the list of bad global warming news: The world is spewing greenhouse gases at a faster rate. Summer Arctic sea ice is at record lows. The ice sheets in Greenland and West Antarctica are melting quicker than expected. Is he the doomsayer global warming skeptics have called him? Mann laughs. This Penn State University professor - and many other climate scientists - are sunny optimists. Hope blooms in the hottest of greenhouses. Climate...

NASA and Columbia University Earth Institute research finds that human-made greenhouse gases have brought the Earth's climate close to critical tipping points, with potentially dangerous consequences for the planet. From a combination of climate models, satellite data, and paleoclimate records the scientists conclude that the West Antarctic ice sheet, Arctic ice cover, and regions providing fresh water sources and species habitat are under threat from continued global warming. The research...

NEW YORK -- Bold new initiatives against global warming have come out of major cities around the world over the past few weeks - with the notable exception of Washington. Meeting in New York this month, dozens of big-city mayors from six continents competed to present the most ambitious plan for reducing emissions of carbon dioxide and other gases that cause global warming. New York Mayor Michael Bloomberg touted his new 127-point plan to cut Gotham's emissions 30 percent by 2030. Los Angeles...

WASHINGTON - One of the world's top scientists on global warming called for the United States to stop building coal-fired power plants and eventually bulldoze older generators that don't capture and bury greenhouse gases. But 159 coal-fired power plants are scheduled to be built in the next decade or so, generating enough power for about 96 million homes, according to a study last month by the U.S. Department of Energy. Burning coal is one of the major sources of carbon dioxide, the chief...

Climatologists at the NASA Goddard Institute for Space Studies (GISS) in New York City have found that 2006 was the fifth warmest year in the past century. Other groups that study climate change also rank these years as among the warmest, though the exact rankings vary depending upon details of the analyses. Results differ especially in regions of sparse measurements, where scientists use alternative methods of estimating temperature change. Goddard Institute researchers used temperature...

Pinpointing pollutant sources is an important part of the ongoing battle to improve air quality and to understand its impact on climate. Scientists using NASA data recently tracked the path and distribution of aerosols -- tiny particles suspended in the air -- to link their region of origin and source type with their tendencies to warm or cool the atmosphere. By altering the amount of solar energy that reaches the Earth's surface, aerosols influence both regional and global climate, but...

MAMMOTH LAKES, Calif. -- The effects of global warming are being felt around the world and unless international efforts are launched within the next 10 years species will disappear and the earth will be a vastly less habitable planet by the end of the century, according to NASA scientist James E. Hansen. "Global warming is already starting, and there's going to be more of it. I think there is still time to deal with global warming, but we need to act soon. Humans now control global climate,...

By JOHN HEILPRIN, Associated Press Writer WASHINGTON - Two federal agencies are investigating whether the Bush administration tried to block government scientists from speaking freely about global warming and censor their research, a senator said Wednesday. Sen. Frank Lautenberg (news, bio, voting record), D-N.J., said he was informed that the inspectors general for the        Commerce Department and        NASA had begun...

WASHINGTON (AP) - The planet's temperature has climbed to levels not seen in thousands of years, warming that has begun to affect plants and animals, researchers report in Tuesday's issue of Proceedings of the National Academy of Sciences. The Earth has been warming at a rate of 0.36 degree Fahrenheit per decade for the last 30 years, according to the research team led by James Hansen of NASA's Goddard Institute for Space Studies in New York. That brings the overall temperature to the warmest...

WASHINGTON -- Coal-burning utilities are passing the hat for one of the few remaining scientists skeptical of the global warming harm caused by industries that burn fossil fuels. Pat Michaels - Virginia's state climatologist, a University of Virginia professor and senior fellow at the libertarian Cato Institute - told Western business leaders last year that he was running out of money for his analyses of other scientists' global warming research. So last week, a Colorado utility organized a...
