A new study shows how huge influxes of fresh water into the North Atlantic Ocean from icebergs calving off North America during the last ice age had an unexpected effect – they increased the production of methane in Earth’s tropical wetlands.

Watching plants perform photosynthesis from space sounds like a futuristic proposal, but a new application of data from NASA's Orbiting Carbon Observatory-2 (OCO-2) satellite may enable scientists to do just that.

June 3, 2015 | Storm-studying scientists have made their next-generation forecasting system available online so the wider weather community can put it to the test. After using the real-time system during short-lived field research campaigns, developers at the National Center for Atmospheric Research (NCAR) are now ready to see how it performs year-round, and they're eager for user feedback.

May 13, 2015 | Before the Rio Grande wends 1,900 miles across the desert Southwest, trickling to its end in the Gulf of Mexico, it begins life as a snow-fed stream in the mountains of Colorado. Despite its relatively short journey through the state, the Rio Grande depends on melting snow in the mountains ringing Colorado's San Luis Valley to deliver a significant portion of the water that will supply farmers and towns downstream in New Mexico, Texas, and, if there's enough left, Mexico.

June 17, 2015 | Water falls from the sky, runs across the earth, funnels into drainages, and fills rivers.  It seems simple. But total precipitation does not equal total streamflow. Along the way, some of the water gets sucked up by plants, absorbed by the soil, or evaporated into the air. A complex array of factors—from wind speed to geology—influences how much precipitation converts into streamflow and at what speed.

April 29, 2015 | Just as waves ripple across a pond when a tossed stone disturbs the water’s surface, gravity waves ripple toward space from disturbances in the lower atmosphere.

Climate and extreme weather: drought in Colorado
February 24, 2015 | Earth’s weather extends into higher regions of the atmosphere than the one we inhabit. But the influence of those regions has been challenging to chart until recently.
