El Nino May Have Helped Magellan Cross The Pacific Ocean![]() A new paper by North Carolina State University archaeologist Dr. Scott Fitzpatrick shows that Ferdinand Magellan's historic circumnavigation of the globe was likely influenced in large part by unusual weather conditions - including what we now know as El Nino - which eased his passage across the Pacific Ocean, but ultimately led him over a thousand miles from his intended destination. ... more Earth Impacts Linked To Human-Caused Climate Change ![]() A new NASA-led study shows that human-caused climate change has impacted a wide range of Earth's natural systems, from permafrost thawing to plants blooming earlier across Europe to lakes declining in productivity in Africa. Cynthia Rosenzweig of NASA's Goddard Institute for Space Science in New York and scientists at 10 other institutions have linked physical and biological impacts since ... more New Findings On Oceanic Nitrogen Levels ![]() As much as a third of the nitrogen entering the world's oceans from the atmosphere is man-made, according to new findings by an international team of scientists. This has significant implications for global climate change because the nitrogen causes increased marine biological activity and CO2 uptake, which in turn produces the potent greenhouse gas nitrous oxide (N20). Published in the ... more Studies Unveil Greenhouse Processes Back 800000 Years ![]() The newest analysis of trace gases trapped in Antarctic ice cores now provide a reasonable view of greenhouse gas concentrations as much as 800,000 years into the past, and are further confirming the link between greenhouse gas levels and global warming, scientists reported in the journal Nature. They also show that during that entire period of time, there have never been concentrations of ... more Over Three Million Burmese Potentially Affected By Cyclone ![]() As many as 3.2 million Burmese are estimated to be affected by the devastation caused by Cyclone Nargis, according to geographic risk models developed by researchers from the Johns Hopkins Bloomberg School of Public Health and Lehman College, CUNY.

The Durham experts will lead an international team of 12 scientists aboard Britain's Royal Research Ship James Cook which will set sail from Ponta Delgada, San Miguel, in the Azores on Friday, May 23. During the five-week ... more Warming Climate Is Changing Life On A Global Scale ![]() A vast array of physical and biological systems across the earth are being affected by warming temperatures caused by humans, says a new analysis of information not previously assembled all in one spot. The effects on living things include earlier leafing of trees and plants over many regions; movements of species to higher latitudes and altitudes in the northern hemisphere; changes in ... more Wildlife numbers plummet globally: WWF ![]() The world's wildlife populations have reduced by around a quarter since the 1970s, according to a major report published Friday by the WWF conservation organization. Marine species have been particularly hard hit as the human population booms, while numbers of birds and, fish and animals have also gone down, said the WWF in a report. The study comes ahead of next week's UN convention on ... more New clean air rules may endanger parks ![]() National parks and wilderness areas may soon have neighboring power plants under a proposed set of air quality rules from U.S. officials, scientists say. Environmental engineer Don Shepherd said the proposed changes by U.S. President George Bush's administration to the Clean Air Act could potentially create 28 new power plants near 10 national parks and pose a significant risk to such ... more Food and climate fears combine to put focus on global biodiversity ![]() In the midst of a global food crisis, experts from around world gather Monday in the German city of Bonn for a marathon conference aimed at ending the destruction of countless plant and animal species. While the extinction of mammals or sea-life have long caught the public imagination, pressing concerns over food prices and stocks, allied to global awareness of the dangers of climate change ... more |
