The United States hasn't experienced the landfall of a Category 3 or larger hurricane in nine years — a string of years that's likely to come along only once every 177 years, according to a new NASA study.
NASA announced this week the creation of the Nexus for Exoplanet Systems Science (NExSS) network that will study planets beyond our solar system for habitability and other features tapping the expertise of researchers at NASA's Goddard Institute for Space Studies, Goddard Space Flight Center and other locations.
While the Goddard Institute for Space Studies was opening the eyes of the world to new areas of Earth systems science in recent decades, its research roots in planetary science have continued. That expertise will now be applied to the new area of exoplanet systems science.
The Goddard Institute for Space Studies is providing expertise to the Nexus for Exoplanet System Science in the area of exoplanet atmospheres and climate. GISS has been a key player in the study of planetary climates and atmospheres for decades.
A new study based in part on NASA satellite data has shown what has been called a "rich-get-richer" pattern in which
an increase in large, well-organized thunderstorms is boosting rainfall in the wettest regions of Earth's tropics.
As global food networks become more complex and interdependent, how concerned should we be about the stability of the system being disrupted by geopolitical, economic, and climatic events? What can we do to avoid future trouble?
The Chances of Another Katrina
Research at the NASA Goddard Institute for Space Studies (GISS) emphasizes a broad study of global change, which is an interdisciplinary initiative addressing natural and man-made changes in our environment that occur on various time scales — from one-time forcings such as volcanic explosions, to seasonal and annual effects such as El Niño, and on up to the millennia of ice ages — and that affect the habitability of our planet.
GISS is located at Columbia University in New York City. The institute is a laboratory in the Earth Sciences Division of NASA's Goddard Space Flight Center and is affiliated with the Columbia Earth Institute and School of Engineering and Applied Science.
