A recent survey shows that greenhouse gas emissions by the Group of Eight industrial nations except Russia fell in 2006, making this the broadest dip since the world started trying to slow climate change in 1990.There was an overall 0.6 percent dip in G8 emissions in 2006 from 2005, likely due to rising oil prices, some measures to curb global warming and a milder winter in the United States in 2006 that depressed energy demand for heating. "It is an encouraging sign that emissions decreased...

A new NASA-led study shows human-caused climate change has made an impact on a wide range of Earth's natural systems, including permafrost thawing, plants blooming earlier across Europe, and lakes declining in productivity in Africa.Cynthia Rosenzweig of NASA's Goddard Institute for Space Science in New York and scientists at 10 other institutions have linked physical and biological impacts since 1970 with rises in temperatures during that period. The study, to be published May 15 in the...

COLLEGE STATION "“ The more you know the less you care "“ at least that seems to be the case with global warming. A telephone survey of 1,093 Americans by two Texas A&M University political scientists and a former colleague indicates that trend, as explained in their recent article in the peer-reviewed journal Risk Analysis. "More informed respondents both feel less personally responsible for global warming, and also show less concern for global warming," states the article,...

LIVERMORE, Calif. "“ Over the past 85 years, humans have helped shape California climate during certain seasons.But that's not necessarily good.Recent research by scientists at the Lawrence Livermore National Laboratory, the University of California, Merced and the National Center for Atmospheric Research shows that California temperatures have jumped statewide by more than 2.1 degrees Fahrenheit between 1915 and 2000. This warming is likely related to human activities.Using data from...

GENEVA -- Two of the most important Greenhouse gases in the Earth's atmosphere reached a record high in 2006, and measurements show that one - carbon dioxide - is playing an increasingly important role in global warming, the U.N. weather agency said Friday. The global average concentrations of carbon dioxide, or CO2, and nitrous oxide, or N2O, in the atmosphere were higher than ever in measurements coordinated by the World Meteorological Organization, said Geir Braathen, a climate specialist...

TRENTON, N.J. -- Wilting heat, deadly storms, flash floods, coastal erosion, more days with unhealthy air - those are just some of the effects of rising temperatures on the Northeast, a group of scientists reported Wednesday. They urged governments and citizens to take steps now to avoid the most devastating consequences of global warming. The Union of Concerned Scientists presented a report detailing the disastrous consequences of climate change on the economy, tourism industry, coastline...

RALEIGH, N.C. -- In North Carolina, global warming isn't a future worry. It's already lapping ashore. Nags Head Mayor Renee Cahoon sees all the proof of climate change she needs at the end of Old Oregon Inlet Road. The street once led to rows of oceanfront houses. Now it ends suddenly in bulldozed piles of sand. Some beach erosion occurs naturally, and development near the ocean tends to make it worse. But some scientists think erosion has grown more pronounced in recent years as the...

BOULDER, Colo. -- Arctic sea ice is melting three times faster than many scientists project, U.S. researchers reported Monday, just days ahead of the next major international report on climate change. Scientists at the National Center for Atmospheric Research and the University of Colorado in Boulder concluded, using actual measurements, that Arctic sea ice has declined at an average rate of about 7.8 percent per decade between 1953 and 2006. By contrast, 18 computer models used by the...

By Duncan, Kirsty For the first twenty years that climate change garnered international attention, gender issues were not on the agenda - although women (1) are generally poorer than men, and (2) are more dependent than men on primary resources (e.g. agriculture) that are threatened by changes in climate. Women often shoulder the responsibility for the household water supply and its purification; in Kenya, for example, carrying water may use up to 85% of a woman's daily energy intake....

WASHINGTON -- By 2020, the United States will emit almost one-fifth more gases that lead to global warming than it did in 2000, increasing the risks of drought and scarce water supplies. That projection comes from an internal draft report from the Bush administration that is more than a year overdue at the United Nations. The Associated Press obtained a copy Saturday. The United States already is responsible for roughly one-quarter of the world's carbon dioxide and other "greenhouse" gases...
