The European Space Agency (ESA) Copernicus Sentinel-2A satellite collected this false-color image over the jagged islands along the west coast of Greenland on Aug. 8, 2017.
Satellites Capture Break-Off of Massive Iceberg in Antarctica
Over the last few months, a chunk of Antarctica's Larsen C ice shelf has been hanging on precariously as a deep crack cut across the ice. Witnessed by the European Space Agency (ESA) Copernicus Sentinel-1 mission, a lump of ice more than twice the size of Luxembourg finally broke off on July 12, 2017.
Record-Low Sea Ice
On Feb. 13, 2017, the combined Arctic and Antarctic sea-ice numbers were at their lowest point since satellites began to continuously measure sea ice in 1979.
Satellite Data Reveal Effects of Aerosols
Earth's atmosphere is dusted with tiny particles known as aerosols, which include windblown ash, sea salt, pollution, and other natural and human-produced materials. Aerosols can absorb or scatter sunlight, affecting how much light reflects back into space or stays trapped in the atmosphere.
Geospatial Science Expert to Help Determine Greenhouse Gas Guidelines
FAYETTEVILLE, Ark. – A geospatial science expert at the University of Arkansas will help refine international guidelines for greenhouse gas inventories that will be considered for adoption by the Intergovernmental Panel on Climate Change. The panel, known as IPCC,...
Mediterranean Drought Worst in 900 Years
A new NASA study used remote-sensing and tree-ring data to conclude that the recent drought that began in 1998 in the eastern Mediterranean Levant region (Cyprus, Israel, Jordan, Lebanon, Palestine, Syria and Turkey) is likely the worst drought of the last nine centuries.
Study Incorporates Ecological Processes Into Earth System Models to Improve Climate Change Predictions
BLACKSBURG, Va., Nov. 23, 2015 — A professor in Virginia Tech’s College of Natural Resources and Environment ( www.cnre.vt.edu) is launching a new project to enable scientists to look many decades ahead and predict the effectiveness of land management practices...
Climate Macroscope: New Software for Finding Tipping Points and Critical Network Structures
WASHINGTON, D.C., November 19, 2015 — If you wanted to know whether shifts in the African climate during Paleolithic times correlated with the appearance and disappearance of hominin species, how would you find the answer? It’s a tricky question because of the...
