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...

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...
