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.

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, was created to provide policymakers with regular assessments of the scientific basis of climate change, its

China's sweeping program to restore forests across the country is working. The vast destruction of China's forests, leveled after decades of logging, floods and conversion to farmland, has become a story of recovery, according to the first independent verification published in today's Science Advances by Michigan State University (MSU) researchers. "It is encouraging that China's

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.

Estimates of future global temperatures based on recent observations must account for the differing characteristics of each important driver of recent climate change, according to a new NASA study published Dec. 14 in the journal Nature Climate Change. To quantify climate change, researchers need to know the Transient Climate Response (TCR) and Equilibrium Climate Sensitivity (ECS)

Paris, Dec. 9, 2015 – As climate change disrupts rural communities around the world, policymakers face the task of helping their societies become more resilient. In many places, though, an information gap prevents decisions from being made with the best available evidence. Now, a new tool from Conservation International (CI) is making a wealth of

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 massive amounts of noisy, complicated data you would need to analyze. Now researchers in

By Chris Crosiar, Office of Basic and Applied Research, National Geospatial-Intelligence Agency (www.nga.mil), Springfield, Va. In my experience as a research and development scientist at the National Geospatial-Intelligence Agency, I recall a time when the mention of climate change was so taboo, analysts could only reference “an environmental anomaly.” Times have changed. During the last
