The Incredible Shrinking Arctic

NASA researchers have released worrying data concerning the rapidly diminishing sea ice in the Arctic Ocean. According to their figures, the perennial ice (which survives the summer melt season and remains year-round) shrank abruptly by 14 percent between 2004 and 2005. Putting the decrease in perspective, the loss represents an area the size of Texas. […]

Alpine Glaciers: Going, Going, Gone!




European Alpine glacial cover will decrease by 80 percent if summer temperatures increase by 5 degrees Fahrenheit, say scientists from the University of Zurich, and will disappear completely by 2100 if temperatures reach 9 degrees Fahrenheit. These alarming predictions, based on numerical modeling experiments, are due to be published in the July 15th edition ofGeophysical […]

Darwin’s Dilemma Solved?




The New York Academy of Sciences Readers & Writers lecture series will play host to biologists Marc Kirschner and John Gerhart on January 25, where they will reveal what they consider to be the answer to one of evolutionary theory’s most puzzling questions. If their theory – that explains seemingly random genetic change – passes […]

Grim Future For Global Water Resources




Two new studies in Nature predict major disruptions to the world’s supplies of fresh water. While some areas will become drier, others will receive much more rainfall, and others will be unable to cope with the run-off from previously ice-bound catchment areas. The first study, from the United States Geological Survey, looks at global shifts […]

Methane’s Effect On Climate Change May Be Twice Previous Estimates




Establishing a suitable model of how the Earth’s climate systems work is a necessary step in determining how much man contributes to climate change. But a recent study may prove that our current models of measuring climate change are dangerously inadequate. Despite the disparity of isolated climate studies, existing scientific consensus models on climate change […]

Climate Change And Vegetation A Complex Feedback




Climatologist Noah S. Diffenbaugh from Purdue University says he has found that events such as storms and heat waves can vary substantially in frequency and severity depending on how vegetation responds to global warming. His study indicates that as vegetation responds to climate change, those changes in ground cover may affect where and how often […]
