The accuracy of computer models that predict climate change has been the subject of debate. A new University of Utah study shows that current climate models are quite accurate and can be valuable tools for those seeking solutions on reversing global warming trends. Most of these models project a global warming trend that amounts to about 7 degrees Fahrenheit over the next 100 years.

One cool year does not erase decades of climate data, nor does it more than minimally change the long-term climate trend, according to one of the world's foremost global climate scientists. Long-term climate change is just that "” long term "” and 12 months of data are little more than a blip on the screen.
A destructive spring freeze that chilled the eastern United States almost a year ago illustrates the threat a warming climate poses to plants and crops, according to a paper just published in the journal BioScience.

The bad news is that the Mississippi Delta is sinking as much as one fifth of an inch per year and sometimes even more. But the good news is that the sinking is mostly limited to the uppermost layer of sediment and the land underneath is much more stable.
To have meaningful impact on managing carbon emissions, we need to think about the problem globally. Integrating science and public policy with the needs of consumers and the global economy is critical if we have any chance of reducing the effects of carbon on the climate, say scientists at the 2008 Annual Meeting of the American Association for the Advancement of Science (AAAS).

More than 600 prominent scientists from across the United States are calling on Congress to pass legislation that will curb America's global warming pollution and help protect wildlife and other natural resources threatened by global warming. Spearheaded by some of America's greatest scientific minds, including Harvard Professor E.O. Wilson, Thomas Lovejoy, Paul Ehrlich and Camille Parmesan, the scientists have sent a letter to Congress urging action.

Scientists have discovered what they think may be another reason why Greenland's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice. They have found at least one "hotspot" in the northeast corner of Greenland -- just below a site where an ice stream was recently discovered.
Ice cores drilled last year from the summit of a Himalayan ice field lack the distinctive radioactive signals that mark virtually every other ice core retrieved worldwide. Scientists believe that the missing signal means that this Tibetan ice field has been shrinking at least since the A-bomb test half a century ago.
Two researchers spent months scouring through old expedition logs and reports, and reviewing 70-year-old maps and photos before making a surprising discovery: They found that the effects of the current warming and melting of Greenland's glaciers that has alarmed the world's climate scientists occurred in the decades following an abrupt warming in the 1920s.
Looking ahead to the U.N. Climate Change Conference that begins next week, a diverse chorus of elected officials and citizens are speaking out to assure the international community that Americans are moving global warming solutions forward, despite the lack of White House leadership.
Kyoto was a valiant first attempt to tackle global carbon emissions, and support for the Kyoto Protocol is still needed in the international community, but it will not be enough to make a breakthrough with climate change. That's according to a letter co-authored by a University of Adelaide climate change expert and published today in the international journal Nature.
A new study shows that long-term climate change may ultimately lead to wars and population decline. The study, published November 19 in the early edition of the journal Proceedings of the National Academy of Sciences (PNAS), revealed that as temperatures decreased centuries ago during a period called the Little Ice Age, the number of wars increased, famine occurred and the population declined.

A panel discussion hosted by the UCLA School of Public Health on the potential impact changes in climate could have on people's health warned of a rise in water-and food-borne illness and infectious diseases. The panelists discussed what individuals, the public health community, and state and local government can do to prepare.
The total economic cost of climate change in the United States will be major and nationwide in scope, but remains uncounted, unplanned for and largely hidden in public debate, says a new study from the University of Maryland.
First, Al Gore won an Academy Award, now he has received the Nobel Peace Prize for bringing global warming to the forefront of public discussion with his film, AN INCONVENIENT TRUTH.
