WASHINGTON -- The Earth is running a slight fever from greenhouse gases, after enjoying relatively stable temperatures for 2,000 years. The National Academy of Sciences, after reconstructing global average surface temperatures for the past two millennia, said Thursday the data are "additional supporting evidence ... that human activities are responsible for much of the recent warming." Other new research showed that global warming produced about half of the extra hurricane-fueled warmth in...

WASHINGTON -- A man stands on a railroad track as a train rumbles closer. "Global warming?" he says. "Some say irreversible consequences are 30 years away. Thirty years. That won't affect me." He steps off the tracks - just in time. But behind him is a little blonde-haired girl left in front of the roaring train. The screen goes black. A message appears: "There's still time." It's just an ad, part of a campaign from the advocacy group Environmental Defense, which hopes to convince Americans...

By Deborah Zabarenko WASHINGTON -- Ozone pollution in the Northern Hemisphere, churned out by factories and vehicles that burn fossil fuels, is a major factor in the dramatic warming of the Arctic zone, NASA climate scientists reported on Tuesday. This finding is surprising, since ozone has been considered a minor player in the study of global climate change, according to Drew Shindell, a research scientist at NASA's Goddard Institute for Space Studies in New York City. Carbon dioxide has...

NEW YORK (Reuters) - NASA's top climate scientist said the Bush administration has tried to stop him from speaking out since he gave a lecture in December calling for prompt reductions in emissions of greenhouse gases, The New York Times said on Saturday. In an interview with the newspaper, James Hansen, director of NASA's Goddard Institute for Space Studies, said that officials at the space agency's headquarters had ordered the public affairs staff to review his lectures, papers,...

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - Scientists say it's not easy to tell if global warming caused hurricanes Katrina and Rita but on Monday they forecast more unpredictable weather as Earth gets hotter. Even skeptics agree that global warming is under way and that human activity is at least in part responsible. Climate experts also agree that this warming is likely to make the weather more extreme -- colder in some places, hotter in others, with...

DENVER (AP) -- Colorado State University scientist Roger Pielke Sr. has resigned from a Bush administration science advisory team in a disagreement over research into the causes of global warming. Pielke, who is also the state climatologist, said the Climate Change Science Program had minimized evidence that factors other than greenhouse gases can contribute to global warming. Pielke also said other members of the team went behind his back to rewrite a final chapter of its report. Pielke...

WASHINGTON (Reuters) - A dispute over whether global warming is really happening may have been caused by the placement of sensors on weather balloons when studies were done in the 1970s, researchers said on Thursday. Very few scientists now dispute that the Earth's temperature is rising, and that this is caused by human activity, including burning fossil fuels such as coal and oil. But there have been some discrepancies that have troubled experts. For instance, some measurements show...

BOULDER - Warmer oceans, more moisture in the atmosphere, and other factors suggest that human-induced climate change will increase hurricane intensity and rainfall, according to climate expert Kevin Trenberth of the National Center for Atmospheric Research. His paper, "Uncertainty in Hurricanes and Global Warming," appears in the Perspectives section of the June 17 issue of Science. "Trends in human-influenced environmental changes are now evident in hurricane regions," says Trenberth....

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
