Following are news releases, features and updates about GISS research for the current year. Archives of past highlights are available for 2014, 2013, 2012, 2011, 2010, 2009, 2008, 2007, 2006, 2005, and 2004.
Estimates of future global temperatures based on recent observations must account for the differing characteristics of each important driver of recent climate change. Researchers need to know the transient response and equilibrium sensitivity of climate forcings.
Thick peat, El Niño weather, and economic development in Indonesia came together to produce prodigious fires and planet-warming emissions. Scientists around the world used many different tools to better understand why the fires were so severe and what their impact was on human health and the environment.
Snow is an important seasonal water source around large mountain chains. A new study has examined the potential effects of declining snow accumulations in many regions around the world, identifying areas that may be particularly vulnerable.
The climate would be a much easier system to study if there was only one thing going on at a time. Unfortunately, all of the different external forcings happen independently. As climate changes, can we make any clear attributions to the individual factors?
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.
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.
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.
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.
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.
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.
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.
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.
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.
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?
A new report by the New York City Panel on Climate Change details significant future increases in temperature, precipitation and sea level in the New York metropolitan area. The report aims to increase current and future resiliency of the communities, citywide systems and infrastructure in the New York metropolitan region to a range of climate risks.
Droughts in the U.S. Southwest and Central Plains during the last half of this century could be drier and longer than drought conditions seen in those regions in the last 1,000 years, according to a new NASA study.
You could hardly miss the media stories about how the past year ranked in terms of global temperatures. Astute readers may ask: how do different institutions come up with slightly different numbers for the same planet?
The year 2014 ranks as Earth's warmest since 1880, according to two separate analyses by NASA and National Oceanic and Atmospheric Administration. The 10 warmest years in the instrumental record, with the exception of 1998, have now occurred since 2000.
