Earth is warming faster than scientists have predicted, in part because industrial greenhouse gas emissions have increased, U.S. scientists say. Scientists say higher temperatures are triggering responses in ecosystems, The Washington Post reported Sunday. We are basically looking now at a future climate that's beyond anything we've considered seriously in climate model simulations, said Christopher Field, founding director of the Carnegie Institution's Department of Global Ecology at...

According to a top climate scientist, warnings about global warming have not been severe enough. Just over a year ago, the Nobel-winning Intergovernmental Panel on Climate Change (IPCC) issued a report warning of expanding deserts, intense storms, rising sea levels, and an extinction of up to 30 percent of animals and plants due to global warming. A recent study suggests that the report underestimated the severity of climate change over the next century, says a senior member of the IPCC. "We...

Greenhouse gases are putting oceans at risk of becoming too acidic to support reefs and marine life, scientists at a U.N. forum in Monaco warned Friday. More than 150 scientists called on governments to take immediate action to reduce carbon dioxide emissions in the Monaco Declaration on Ocean Acidification drafted during the conference, the United Nations said in a news release. In the declaration, the marine scientists from 26 countries said acidity levels were accelerating and their...

Despite ongoing harsh winter conditions in North America and Europe, a survey finds a consensus among scientists that global warming continues unabated. The University of Illinois-Chicago surveyed an international group of 3,146 earth scientists and found overwhelming agreement that during the past 200-plus years, mean global temperatures have been rising, and that human activity is a ongoing significant contributing factor in changing mean global temperatures. The survey was conducted by...

While the harsh winter pounding many areas of North America and Europe seemingly contradicts the fact that global warming continues unabated, a new survey finds consensus among scientists about the reality of climate change and its likely cause.A group of 3,146 earth scientists surveyed around the world overwhelmingly agree that in the past 200-plus years, mean global temperatures have been rising, and that human activity is a significant contributing factor in changing mean global...

A wide range of Earth scientists say humans contribute significantly to global warming, suggests a poll conducted by the University of Illinois at Chicago. The poll should dispel doubts by some that a consensus about global warming exists among scientists, said Peter Doran, a University of Illinois professor who conducted the poll with students last year. The 3,146 Earth scientists interviewed around the world overwhelmingly agreed that global temperatures have risen in the last 200-plus...

Rising Seas, Severe Drought, Could Come in Decades, Says U.S. Report The United States could suffer the effects of abrupt climate changes within decades "” sooner than some previously thought - says a new government report. It contends that seas could rise rapidly if melting of polar ice continues to outrun recent projections, and that an ongoing drought in the U.S. west could be the start of permanent drying for the region. Commissioned by the U.S. Climate Change Science Program, the...

Global warming has turned into a major ticking time bomb for President-elect Barack Obama. Since former president Bill Clinton's inauguration in 1993, summer Arctic sea ice has lost the equivalent of Alaska, California and Texas. Since Clinton's second inauguration, the 10 hottest years on record have occurred. Global warming is accelerating. Time is close to running out, and Obama knows it. "The time for delay is over; the time for denial is over," he said on Tuesday after meeting with...

Nearly 1,000 scientists from Canada and 15 other nations are in Quebec for the Arctic Change 2008 International Conference. Climate change and its impacts are accelerating at unexpected rates with global consequences, conference officials said Thursday. Scientific information presented has raised to new levels our concern regarding the changes that are taking place in the Arctic. The social and economic challenges in the Arctic are only going to increase exponentially. Among other things,...

The first comprehensive reconstruction of an extreme warm period shows the sensitivity of the climate system to changes in carbon dioxide (CO2) levels as well as the strong influence of ocean temperatures, heat transport from equatorial regions, and greenhouse gases on Earth's temperature. New data allow for more accurate predictions of future climate and improved understanding of today's warming. Past warm periods provide real data on climate change and are natural laboratories for...
