Pop quiz: What spacecraft holds the record for longest-surviving mission on the bitterly cold and dusty surface of Mars? As of Thursday, there's a new - but possibly temporary - champion.
New study links dust to increased glacier melting, ocean productivity
A University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study shows a link between large dust storms on Iceland and glacial melting. The dust is both accelerating glacial melting ...
Mars Reconnaissance Orbiter monitoring dust storm
(Phys.org)—A Martian dust storm that NASA's Mars Reconnaissance Orbiter has been tracking since last week has also produced atmospheric changes detectable by rovers on Mars. ...
Dust plays larger than expected role in determining Atlantic temperature
(PhysOrg.com) -- The recent warming trend in the Atlantic Ocean is largely due to reductions in airborne dust and volcanic emissions during the past 30 years, according to a new study.
Regional dust storm dissipating
(Phys.org)—A regional dust storm on Mars, tracked from orbit since Nov. 10, appears to be abating rather than going global.
1934 drought was worst of the last millennium, study finds
The 1934 drought was by far the most intense and far-reaching drought of the last 1,000 years in North America, and was caused in part by an atmospheric phenomenon that may have also led to the current drought ...
