Will ocean currents carry oil and byproducts from the Deepwater Horizon wellhead beyond the Gulf of Mexico and out into the open Atlantic Ocean? Climate data and computer models help scientists predict how and where.

Chris Landsea talks about how global warming may change hurricanes: on average, not more storms, but stronger ones.

 Researchers at NOAA’s National Climatic Data Center collaborate with tropical cyclone centers and scientific agencies around the world to assemble and maintain the International Best Track Archive for Climate Stewardship (IBTrACS), an inventory of tropical cyclones.

How is climate change affecting bird migration patterns? Birdwatchers across the country and around the world are contributing their time, both in the field and online, to answer that question.

Scientists examine data from computer models to generate simulations of sea ice thickness now and three decades into the future.

Six managers of State Coastal Zone Programs and National Estuarine Research Reserves comment on their plans for adapting to climate change.

Twice a month, scientists send weather balloons into the air to collect data about the atmosphere, from the ground all the way up to the darkness of near space. Many gathered for the launch of last week’s balloon, which marked 30 years of NOAA water vapor measurements in Boulder.

Iceland’s Eyjafjallajökull Volcano roared to life on April 14, 2010, injecting billowing clouds of steam and volcanic ash into the atmosphere.

The Global Hawk research aircraft soars to hard-to-reach areas of the atmosphere to collect samples of trace gases and chemicals. Find out just how high the Global Hawk flies.
