Recent studies show the world’s ocean is heating up as it absorbs most of the extra heat being added to the climate system from the build-up of heat-trapping gases in the atmosphere. This climate trend, and many others, are documented in NOAA’s newly released 2009 State of the Climate Report.
CalNex—an intense data collection campaign to characterize the complicated interactions of air quality and climate over California—used an array of instruments and platforms this spring for a close look at greenhouse gases and pollutants.
In 2007, Arctic sea ice retreated so dramatically that it broke all previous records for sea ice minimum for July through October. Is this year’s summer ice melt season on track to surpass 2007?
At the highest point atop the Greenland Ice Sheet, Matthew Shupe and his colleagues are installing a suite of climate and weather instruments. Their goal is to better understand the role of clouds in the rapid warming observed across the Arctic region.
Across the globe, over land as well as sea, Earth’s average surface temperature for April 2010 made it the warmest April on record.
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.
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.
