Scientists at Germany's Kiel University predict the Earth's temperature will stay roughly the same in the coming decade as the planet's natural climate cycle enters a cooling phase.  The researchers developed computer models for their analysis, which suggest the cooling phase will counter warming from greenhouse gas emissions.But thereafter, the researchers expect temperatures to begin rising quickly by about 2020.The forecast centers around the ocean's natural temperature cycles, called...

California Governor Arnold Schwarzenegger predicted Friday that an international deadlock over how to deal with global warming will end once President Bush leaves office, while a leading expert warned of dire consequences if urgent action is not taken. Schwarzenegger spoke at a conference at Yale University in which 18 states pledged to take action on climate change. He noted a dispute over whether the U.S. should commit to reducing its greenhouse gas emissions before China and India do the...

According to the Intergovernmental Panel on Climate Change (IPCC), the average rise in global sea levels will be 28 to 43 centimeters (1 "“ 1.4 feet) by 2100. However, according to a new scientific analysis this predicted number is substantially low, and sea levels could actually rise by nearly one and a half meters (almost 5 feet) in that same time frame. These findings were presented in Vienna at the European Geosciences Union annual meeting by a UK/Finnish team which built a computer...

Scientists in the U.K. have reported evidence that further refutes one theory of global climate change.In the heated debate over global warming, there is an opposing idea, called the cosmic ray theory, which contends that climate change is simply caused by cosmic rays coming from the sun.However, researchers at Lancaster University reported in the Institute of Physics journal that there has been no correlation between solar activity and the Earth's climate.Pioneered by Dr. Henrik Svensmark at...

With digital imaging techniques, scientists find new data in old aerial photographsA comprehensive new study authored by University at Buffalo scientists and their colleagues for the first time documents in detail the dynamics of parts of Greenland's ice sheet, important data that have long been missing from the ice sheet models on which projections about sea level rise and global warming are based. The research, published online this month in the Journal of Glaciology, also demonstrates how...

U.N. Secretary-General Ban Ki-moon reported that global warming could come at a high economic cost to the world. Ban estimates that it could cost up to $20 trillion over two decades for cleaner energy sources, harming those who earn low incomes and are unable to quickly adapt.In his 52-page report, Ban says that global investments of $15 trillion to $20 trillion over the next 20 to 25 years may be necessary "to place the world on a markedly different and sustainable energy trajectory."The...

By McKenney, Daniel W Pedlar, John H; Lawrence, Kevin; Campbell, Kathy; Hutchinson, Michael F Currently predicted change in climate could strongly affect plant distributions during the next century. Here we determine the present- day climatic niches for 130 North American tree species. We then locate the climatic conditions of these niches on maps of predicted future climate, indicating where each species could potentially occur by the end of the century. A major unknown in this work is the...

It's not every day that a NASA scientist can wake up and think, "Hey, I did something for world peace." But on Monday, Dec. 10, many NASA Earth scientists did exactly that. In Oslo, Norway, the King of Sweden presented the shared 2007 Nobel Peace Prize to former U.S. Vice President Al Gore and to representatives of a United Nations panel that has spent two decades assessing Earth's changing climate and predicting where it is headed. Hundreds of NASA scientists contributed to the United...

WASHINGTON -- For the first time, more than 200 of the world's leading climate scientists, losing their patience, urged government leaders to take radical action to slow global warming because "there is no time to lose." A petition from at least 215 climate scientists calls for the world to cut in half greenhouse gas emissions by 2050. It is directed at a conference of diplomats meeting in Bali, Indonesia, to negotiate the next global warming treaty. The petition, obtained by The Associated...

NEW DELHI -- A U.N. climate change conference in Indonesia may produce a roadmap for countries to reduce their global-warming emissions after the Kyoto protocol expires in 2012, a scientist said Monday. World leaders will start negotiations next month on the resort island of Bali for a replacement to the Kyoto protocol, which requires 35 industrial nations to cut their global-warming emissions 5 percent below 1990 levels by 2012, when the accord expires. "What may happen in Bali is a likely...
