CO2 Increase Can Intensify Future Droughts in Tropics, Study Suggests

CO2 Increase Can Intensify Future Droughts in Tropics, Study Suggests

AUSTIN, Texas — A new study suggests that increases in atmospheric CO2 could intensify extreme droughts in tropical and subtropical regions — such as Australia, the southwest and central United States, and southern Amazonia — at much a faster rate than previously anticipated, explains University of Texas at Austin professor Rong Fu in a commentary in…   » Continue Reading

A 3-D View of the Greenland Ice Sheet Opens Window on Ice History

A 3-D View of the Greenland Ice Sheet Opens Window on Ice History

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.

Too Hot to Exercise? New Research Links Obesity to Temperature and Humidity

Too Hot to Exercise? New Research Links Obesity to Temperature and Humidity

If you live in the South and have trouble exercising during the muggy summer months, you’re not alone. New research by researchers at The University of Texas at Austin has found that adults are less physically active — and more obese — in counties where summers are hot, especially if they are also humid or…   » Continue Reading

Symbiotic Fungi Inhabiting Plant Roots Have Major Impact On Atmospheric Carbon

Symbiotic Fungi Inhabiting Plant Roots Have Major Impact On Atmospheric Carbon

AUSTIN, Texas — Microscopic fungi that live in plants' roots play a major role in the storage and release of carbon from the soil into the atmosphere, according to a University of Texas at Austin researcher and his colleagues at Boston University and the Smithsonian Tropical Research Institute.

Risk of Amazon Rainforest Dieback is Higher Than IPCC Projects

Risk of Amazon Rainforest Dieback is Higher Than IPCC Projects

AUSTIN, Texas  —  A new study suggests the southern portion of the Amazon rainforest is at a much higher risk of dieback due to stronger seasonal drying than projections made by the climate models used in the latest report by the Intergovernmental Panel on Climate Change (IPCC).

Rainfall in South Pacific Was More Variable Before 20th Century

Rainfall in South Pacific Was More Variable Before 20th Century

AUSTIN, Texas — A new reconstruction of climate in the South Pacific during the past 446 years shows rainfall varied much more dramatically before the start of the 20th century than after. The finding, based on an analysis of a cave formation called a stalagmite from the island nation of Vanuatu, could force climate modelers to adjust…   » Continue Reading

Coastal Antarctic Permafrost Melting Faster Than Expected

Coastal Antarctic Permafrost Melting Faster Than Expected

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…   » Continue Reading

Scientists Image Vast Subglacial Water System Underpinning West Antarctica’s Thwaites Glacier

Scientists Image Vast Subglacial Water System Underpinning West Antarctica’s Thwaites Glacier

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 canal system beneath…   » Continue Reading

Scientists Launch Ocean Expedition to Study Climate Change and Mountain Building in Gulf of Alaska

Scientists Launch Ocean Expedition to Study Climate Change and Mountain Building in Gulf of Alaska

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…   » Continue Reading
