Fires in Indonesia are persistent, difficult to extinguish, and very polluting. Climatologists worry that this year could be very bad as a strong El Niño influences reduces regional rainfall. (2015-09-27)
Every summer, high school and undergraduate students team up with teachers and NASA scientists at NASA GISS in New York City. Known as the New York City Research Initiative, the program brings students and teachers face-to-face with premier scientists. (2015-09-16)
The nation‘s problem of sea level rise is also NASA‘s problem, and not just because several satellites and hundreds of Earth scientists are monitoring the rising seas. Sea level rise hits especially close to home because half to two-thirds of NASA‘s infrastructure and assets stand within 16 feet of sea level. (2015-08-26)
Larry Travis and Cynthia Rosenzweig from the Goddard Institute for Space Studies in New York City as well as Lorraine Remer, an affiliate of the Goddard Space Flight Center in Maryland, have been named fellows by the American Geophysical Union. (2015-08-10)
To better understand factors affecting the range of habitable conditions of exoplanets, GISS climate modelers go back in time to simulate the “Snowball Earth” conditions of 720 to 635 million years ago and find that complete freeze-over is hard to achieve. (2015-08-04)
The staff of the NASA Goddard Institute for Space Studies have voted the journal article “CMIP5 historical simulations (1850-2012) with GISS ModelE2” by Ron Miller et al. as the top work among over 130 research publications by institute staff to have been published in 2014. (2015-06-12)
Megadroughts Projected for West
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.
