Warm Rivers Play Role in Arctic Sea Ice Melt
The heat from warm river waters draining into the Arctic Ocean is contributing to the melting of Arctic sea ice each summer, a new NASA study finds.
Southern Patagonia Ice Field
With an area of 13,000 square kilometers (5,000 square miles), the Southern Patagonia Ice Field is the largest temperate ice sheet in the Southern Hemisphere. This grand panorama shows that many glacier tongues showed significant annual “retreat” of their ice fronts, a familiar signal of climate change.
Decline Of Bronze Age Megacities Linked To Climate Change
Scientists have demonstrated that an abrupt weakening of the summer monsoon affected northwest India 4,100 years ago. The resulting drought coincided with the beginning of the decline of the metropolis-building Indus Civilization, suggesting that climate change could be why many of the major cities of the civilization were abandoned.
World Begins 2014 With Unusual Number Of Extreme Weather Events
UN’s World Meteorological Organisation says recent extremes of heat, cold and rain are almost certainly interlinked.
Warming from Arctic Sea Ice Melting More Dramatic than Thought
Melting Arctic sea ice has contributed considerably more to warming at the top of the world than previously predicted by climate models, according to a new analysis of 30 years of satellite observations.
Island Nation Takes On The World’s Polluters
What are the obligations under international law of a State for ensuring that activities under its jurisdiction or control that emit greenhouse gases do not cause, or substantially contribute to, serious damage to another State or States? Vulnerable countries, like Palau, that have not contributed to global warming, pressed this question in front of the ICJ.
Scientists Record Massive Coastal Erosion in Cornwall
Experts have found the equivalent of three Olympic-sized swimming pools of cliff has been swept from a short stretch of shore around Porthleven, Cornwall. The shocking scale of the loss of tonnes of soil and rock due to erosion over the past month is more than 850 times the normal expected levels.
Drought Stressing California’s Plantscape
Persistent dry weather has grown more worrisome in the American West, with nearly two thirds of the region experiencing some level of drought. By most measures, the state of California is suffering through the worst of it.
A Look Back and Ahead at Greenland’s Changing Climate
Over the past two decades, ice loss from the Greenland Ice Sheet increased four-fold contributing to one-quarter of global sea level rise. The waters of the North Atlantic Ocean, which surround southern Greenland, are presently the warmest they have been in the past 100 years.
