Sea Level Rise Accelerating

Rutgers University scientists, reporting in the journalScience, say that global ocean levels are rising twice as fast today as they were 150 years ago, and warming from human activities appears to be the culprit. The speed of the rise today is two millimeters per year, compared to one millimeter annually for the past several thousand […]

New Climate Studies Predict Dire Future




Two new studies released this week paint a gloomy picture of a planet changed beyond recognition by the impact of climate change. The first study, from the Lawrence Livermore National Laboratory, looked at the likely outcomes if fossil fuels continue to be used as they are now until depleted. Using a coupled climate and carbon […]

Rate of Climate Change Increasing




The finding last week from NASA that summertime Arctic sea ice was declining at such a rate that it may disappear by the end of the century has been strengthened by scientists from Germany who say that the rate of climate change is increasing. NASA used satellite imagery to examine the extent of Arctic sea […]

Warming Oceans Behind Stronger Hurricanes?




Researchers from the Georgia Institute of Technology and the National Center for Atmospheric Research (NCAR) say the number of category 4 and 5 hurricanes (called typhoons or cyclones in other parts of the world) worldwide has nearly doubled over the past 35 years. The North Atlantic appears to be the area worst affected. Category 4 […]

New Slant On Volcanic Climate Change




Scientists have known for some time that airborne volcanic particles (aerosols) can reflect the Sun’s rays back out into space and cool the planet for relatively short periods. But now, British scientists have discovered another cooling mechanism triggered by volcanic activity that has the potential to cool the Earth for much longer periods. Vincent Gauci, […]

Arctic Lakes Shrinking




Arctic warming could be behind a decrease in the number and size of Arctic lakes, say researchers from the University of Alaska Fairbanks and the University of California Los Angeles. Their study, appearing in Science, compares satellite photographs of Siberia taken in the 1970s to photographs from 1997-2004. Researcher Larry Hinzman, from the University of […]

Glaciers May Be Shrinking But Antarctic Ice Sheet Gains Mass




While some climate change research suggests that global sea levels are rising due to global warming and the shrinkage of glaciers, a new study in Science has found that the interior of the East Antarctic ice sheet is actually gaining mass. Curt Davis, a researcher at the University of Missouri-Columbia, observed the ice sheet over […]
