Researchers at the National Center for Atmospheric Research (NCAR) report that when three atmospheric patterns came together over the Indian and Pacific oceans, they drove so much precipitation over Australia in 2010 and 2011 that the world’s ocean levels dropped measurably. The new research, published in Geophysical Research Letters, notes that the continent of Australia […]
Climatologists examining the relationship between sea level and carbon dioxide (CO2) concentrations over the last 40 million years have found that present day greenhouse gas concentrations (around 400 parts per million) have historically been associated with sea levels at least 30 feet above current levels. The study, appearing in Proceedings of the National Academy of […]
A University of Colorado at Boulder study indicates meltwater periodically overwhelms the interior drainpipes of Alaska’s Kennicott Glacier, causing it to lurch forward. Similar processes may be behind the acceleration of glaciers observed recently on the Greenland ice sheet, write the researchers in Nature Geoscience. According to CU-Boulder Professor Robert Anderson, the amount of water […]
