A new study led by NASA researchers shows that half-a-dozen key glaciers in the West Antarctic Ice Sheet are in irreversible decline. The melting of these sprawling icy giants will affect global sea levels in the centuries ahead.
The Jason-2 satellite sees something brewing in the Pacific. Researchers say it could be a significant El Niño with implications for global weather and climate.
NASA is about to launch a satellite dedicated to the study of the greenhouse gas carbon dioxide. The Orbiting Carbon Observatory (OCO-2) will quantify global CO2 sources and sinks, and help researchers predict the future of climate change.
Almost 30 years after the Montreal Protocol put the brakes on ozone-depleting chemicals, one compound remains stubbornly and mysteriously abundant in the atmosphere. NASA scientists are tracking down the source and studying its effect on the ozone layer.
As climate change continues to hammer Arctic sea ice, pushing back its summertime boundaries to record-high latitudes, NASA is flying an innovative airborne mission to find out how these developments will affect worldwide weather.
Arctic and Antarctic sea ice are both affected by climate change, but the two poles of Earth are behaving in intriguingly different ways.
NASA has launched SMAP, a new satellite to study water, not in oceans or lakes but in the soil beneath our feet. This often overlooked repository of water can have big effects on weather, climate, drought and agriculture.
The Amazon rainforest and the Sahara desert seem utterly different. Yet NASA satellites have discovered a surprising connection that intimately links these two disparate parts of our planet.
The common roundworm shares a surprising amount of genetic material with humans - enough, in fact, to make them the good substitutes for astronauts in low-gravity medical studies.
