Climate scientists study the odds of a U.S. megadrought

ITHACA, N.Y. – To help untangle fact from speculation, Cornell climate scientists and their colleagues have developed a “robust null hypothesis” to assess the odds of a megadrought – one that lasts more than 30 years – occurring in the western and southwestern United States. The research was published online in the Journal of Climate. […]

West Nile virus and infectious diseases a concern in flooded areas

Residents in areas hit by Hurricanes Harvey and Irma continue their recovery efforts, where a major concern is standing water in homes, streets and populated areas. Isaac B. Weisfuse, a medical epidemiologist at Cornell University with more than 25 years of experience in public health at the local and national levels, says it’s important for […]

Caribbean drought – a glimpse of the future under climate change

Toby Ault, professor in Cornell’s department of earth and atmospheric sciences says the drought conditions throughout the Caribbean are a possible glimpse of what climate change will look like. Ault was the lead researcher on several recent studies that predicted prolonged drought risk in the Caribbean region – as well as many parts of the […]

Study: Global rainfall satellites require massive overhaul

ITHACA, N.Y. – Circling hundreds of miles above Earth, weather satellites are working round-the-clock to provide rainfall data that are key to a complex system of global flood prediction. A new Cornell University study warns that the existing system of space-based rainfall observation satellites requires a serious overhaul. Particularly in many developing countries, satellite-based flood […]

Rosetta results crucial to understand early solar system

Lisa Kaltenegger, professor of astronomy in the College of Arts and Sciences at Cornell University and director of Cornell’s Institute for Pale Blue Dots, says while Rosetta’s results show Earth’s water probably did not come from comets, its research is still crucial to understanding the early solar system. Kaltenegger recently published a paper showing where […]

Southwest may face ‘megadrought’ this century

Due to global warming, scientists say, the chances of the southwestern United States experiencing a decade long drought is at least 50 percent, and the chances of a “megadrought” – one that lasts over 30 years – ranges from 20 to 50 percent over the next century. The study by Cornell University, University of Arizona […]
