Climate change will hit the economy at least as much as the credit crunch, said authors of a new study referring to the possible futures of global warming. British-based Forum for the Future, a charitable think-tank, and researchers from Hewlett-Packard Labs, said they wanted to stir debate about how to avert the worst effects of global warming by presenting a radical set of predictions. In the scenarios researchers also wrote of refugees moving to Antarctica by 2030 because of rising...

The head of the U.N. Climate Panel said on Tuesday that evidence is mounting day by day that mankind is to blame for climate change, and the financial crisis is a temporary setback in the hunt for solutions. The downturn could dominate for 2-3 months before politicians return to focus on fixing long-term problems like global warming, said Rajendra Pachauri, whose panel shared the 2007 Nobel Peace Prize with former U.S. vice president Al Gore. "The evidence...is getting stronger by the day. We...

Dutch scientists said on Wednesday that by the year 2100 the days will become dangerously hot due to climate change, and that the U.S. Midwest and the Mediterranean region might reach temperatures well above 40 degrees Celsius (104 F). They said the likely jump in temperatures on the hottest summer days would far outpace the average of year-round global warming this century projected by the U.N. Climate Panel. Such predicted heatwaves can be a big threat to human health. "The extremes warm...

Climate change alters growing conditions in many regions of the world. How global warming could affect Germany's flora researchers have now simulated using computer models. One in five of Germany's plant species could lose parts of its current range, a study by scientists at the Helmholtz Centre for Environmental Research (UFZ), the Potsdam Institute for Climate Impact Research (PIK) and the French Laboratoire d'Ecologie Alpine reveals. Species distributions will be rearranged as a result of...

The prospect of climate change sparking food and water shortages in the Middle East is less likely than previously thought, with new research by an Australian climate scientist suggesting that rainfall will be significantly higher in key parts of the region. Recent projections from the Intergovernmental Panel on Climate Change (IPCC) raised fears that storm activity in the eastern Mediterranean would decline this century if global warming continues on present trends. In turn, that would have...

Economically, the steps taken to reduce global climate change will not be a wise investment if money is solely aimed at curbing greenhouse gas emissions, according to a study conducted by researchers in the U.S. and Ireland.Researchers presented a plan on Thursday that they said would help people adapt to droughts or rising seas cased by global warming, while funding research of new technology and curbing emissions.  They estimate the plan will cost $800 billion over the next 100 years,...

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...

Black carbon, the stuff that gives soot its dirty color, could be the second most important contributor to climate change after carbon dioxide and a key to preventing warming, at least in the short-run, a new study suggests. Black carbon is a type of aerosol - a small particle suspended in the atmosphere - that is produced in diesel exhaust and when wood, coal or other types of solid fuel are burned. Like other aerosols, soot particles absorb and scatter the sun's radiation; black...

UN meteorologists say the cooling effect of the La Nina current in the Pacific will cause global temperatures to drop slightly this year. Michel Jarraud, secretary-general of the World Meteorological Organization, said it was likely that La Nina would continue into the summer. Global temperatures haven't risen since 1998, leaving many to question the climate change theory. However, experts say we are still clearly in a long-term warming trend and new record high temperatures are forecasted...

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...
