  Scientists using ice-penetrating radar data collected by NASA’s Operation IceBridge and earlier airborne campaigns have built the first comprehensive map of layers deep inside the Greenland Ice Sheet, opening a window on past climate conditions and the ice sheet’s potentially perilous future. This new map allows scientists to determine the age of large swaths…

Each summer, India is pounded with intense rainfall, causing flooding and landslides that destroy homes and wreak havoc on communities. But the billion-plus population relies on the monsoon season to bring vital rains to India’s farmland. Yet it remains unclear exactly how the Indian monsoon developed in the past—and, more importantly, how it might change…

A paper by Ian Dalziel of The University of Texas at Austin’s Jackson School of Geosciences, published in the November issue of Geology, a journal of the Geological Society of America, suggests a major tectonic event may have triggered the rise in sea level and other environmental changes that accompanied the apparent burst of life. The…

Variations in the rate of global warming since the 1970s were not caused by atmospheric changes that affect how much solar radiation reaches the Earth’s surface, a new study says.Over the past century, rising greenhouse gas levels have caused global average temperatures to increase, climate scientists Kaicun Wang and Robert Dickinson write in the Proceedings…

For the first time, scientists have documented an acceleration in the melt rate of permafrost, or ground ice, in a section of Antarctica where the ice had been considered stable. The melt rates are comparable with the Arctic, where accelerated melting of permafrost has become a regularly recurring phenomenon, and the change could offer a…

Los Angeles Times, July 13, 2013 Featuring: Ian Dalziel Ancient volcanoes discovered deep in the ocean off Antarctica may explain a climate mystery critical to predicting Earth’s fate as humans pump more carbon dioxide into the atmosphere. University of Texas geologists dredging thousands of feet below the surface of the central Scotia Sea off the…

USA Today, July 9, 2013 Featuring: J.P. Nicot Texas’ current drought is caused by changes in ocean circulation patterns such as La Nina, anthropogenic climate change, and other factors. One thing intensifying the drought’s impact is hydraulic fracturing. Water consumption for fracking in the state jumped 125% in three years and will continue to increase…

AUSTIN, Texas — In a development that will help predict potential sea level rise from the Antarctic ice sheet, scientists from The University of Texas at Austin’s Institute for Geophysics have used an innovation in radar analysis to accurately image the vast subglacial water system under West Antarctica’s Thwaites Glacier. They have detected a swamp-like…

Rising Sea Level Tied to Faster Melt

Wall Street Journal, June 2, 2013 Featuring: Clark Wilson Accelerated melting of polar ice sheets and mountain glaciers was the driving factor behind a rise in the global sea level of 16.8 millimeters, or about two-thirds of an inch, between 2005 and 2011, according to a study published Sunday in Nature Geoscience. The study resolves long-standing…

An international team of 34 scientists sets sail today aboard the scientific ocean drilling vessel JOIDES Resolution to collect sediments in the Gulf of Alaska and investigate the interactions between long-term global climate change and the simultaneous growth of mountain belts. The team is co-led by Sean Gulick, research associate professor at The University of Texas…
