Aerosol particles can increase the lifespans of large storm clouds by delaying rainfall, making the clouds grow larger, and producing more extreme storms when rain finally does come, according to new research.Read more
A new forecast created by UT Austin and the Texas Water Development Board should better predict summer droughts in Texas. The forecast shows a rainy summer across the state.
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 the March 13 edition of Proceedings of the National Academy of Sciences.Read more

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).Read more
Scientists at UT-Austin are at the forefront of research to make the state better prepared for future water shortages. Five key lessons (and challenges) from the state's worst single-year drought in history.Read more
