NASA Goddard Institute for Space Studies

WELCOME

The NASA Goddard Institute for Space Studies (GISS), at Columbia University in New York City, is a laboratory of the Earth Sciences Division of NASA's Goddard Space Flight Center and a unit of the Columbia University Earth Institute. Research at GISS emphasizes a broad study of global climate change.

NEWS AND FEATURES

* New Observing Technique Turns Gray Skies Blue
A new detection technique and a new satellite instrument should help ease the struggle of detecting tiny particles in the air that may affect global climate. (Mar '09)

* Solar Variations and Climate
Modeling studies show that changes in solar irradiance that occur during the solar cycle have an influence on rainfall patterns, much like weighting the dice. (Jan '09)
+ Read Science Brief

* Separating the Man-Made from the Natural
Analyzing anthropogenic signals in the climate records requires the ability to distinguish them from natural effects with similar time scales. (Dec '08)
+ Read Science Brief

* Looking Both Ways at Pollution
Regulation of pollutants often treats their air quality and climate change effects separately, but a unified approach may produce better results. (Dec '08)
+ Read Science Brief

* How Much CO2 Should We Aim For?
A new study suggests that humanity must take prompt action to begin reducing the amount of carbon dioxide in the atmosphere to 350 parts per million. (Dec '08)
