Glowing electric-blue at the edge of space, noctilucent clouds have surprised researchers by appearing early this year. The unexpected apparition hints at a change in the "teleconnections" of Earth's atmosphere.
Arctic permafrost soils contain more accumulated carbon than all the human fossil-fuel emissions since 1850 combined. Warming Arctic permafrost, poised to release its own gases into the atmosphere, could be the "sleeping giant" of climate change.
California is experiencing a historic drought--by some measures the deepest in more than 100 years. NASA researchers are investigating a number of explanations for what the underlying cause may be.
NASA and JAXA are about to launch a new satellite that can see through storms, tracking rain and snow around the globe better than any previous observatory. The Global Precipitation Measurement Core Observatory is scheduled to lift off from Japan on Feb. 27th.
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.
