Both tree rings and similar rings in ocean coral can tell scientists about rainfall and temperatures during a single growing season.
For six weeks every summer between 1989 and 1993, Alley and other scientists pushed columns of ice along the science assembly line, labeling and analyzing the snow for information about past climate
Researchers use MODIS images to show Antarctica like you've never seen it before.
Move over, corn. According to a satellite-based estimate, lawns constitute the largest area of irrigated crops in America.
In September 2008, after years of population declines, NOAA declared the Chesapeake Bay’s crab fishery a federal disaster (press release). This article from 2005 describes how NASA scientists used satellite…
Astronauts onboard the International Space Station (ISS) have many tasks, but a consistent favorite is taking photographs of Earth.
12 months of high-resolution global true color satellite imagery.
NASA-funded ecologists studying the Amazon Rainforest use satellite data to help fight out-of-control fires in Acre, Brazil.
Containing fossilized microscopic plants and animals and bits of dust swept from the continents, the layers of sludge on the ocean floor provide information for scientists trying to piece together the climates of the past.
When Program Managers of the U.S. Antarctic Program had to figure out how to get supplies to research camps in Antarctica, they turned to NASA sensors for information.
NASA satellite data help the Antarctic Traverse Team avoid danger and beat a path to the South Pole.
By analyzing data from the MISR instrument, scientists discover that a unique type of cloud formation is much more prevalent than previously believed.
On August 28, 2004, NASA celebrated the 40th anniversary of the launch of the Nimbus-1 Earth-observation satellite. Starting in 1964 and for the next twenty years, the Nimbus series of missions was the United States' primary research and development platform for satellite remote-sensing of the…
Twenty-five years of NASA scientists' research in Antarctica and Greenland show that even huge ice sheets can change more quickly than scientists thought, causing sea level to rise.
Like detectives reconstructing a crime scene, paleoclimatologists scour the Earth for clues to understand the climates of the past and to learn how and why climate changes.
A regional climate model and NASA satellite data say land cover change in south Florida has created both hotter, drier summers, and more severe freezes in the winter.
Oxygen is one of the most significant keys to deciphering past climates.
When the crew of the Cheyenne set out to break the round-the-world sailing record in March 2004, they would never have guessed what an unusual storm they would meet along the way.
For more than a decade, geologist Bob Brakenridge has been pioneering the use of satellite data for monitoring floods.
Disaster-related economic losses topped $145 billion in 2004, the latest in a disturbing upward trend. Has climate change increased the number and severity of natural disasters, or is the rising cost of natural disasters due to other human factors?
In a rainforest, visible effects of drought can be subtle. An experiment that mimicked the impact of a severe El Nino in the Amazon revealed surprising signs of stress that could be seen from space.
In February 2000, NASA's Terra satellite began measuring Earth's vital signs with a combination of accuracy, precision, and resolution the world had never before seen. While the mission is still in the process of fulfilling its main science objectives, Terra's portfolio of achievements to date…
Examples of student-scientist partnerships demonstrate important benefits and lessons learned for both groups.
Where real-world weather observations are scarce, scientists are estimating winds by tracking the movement of clouds and water vapor between consecutive Terra and Aqua satellite images. In a new Earthsky podcast,…
