Computer models show how skyborne seawater particles change cloud brightness, temperature, rain patterns Ships blowing off steam are helping researchers understand how manmade particles might be useful against global warming. New results from modeling clouds like those seen in shipping lanes reveal the complex interplay between aerosols, the prevailing weather and even the time of day the aerosol particles hit the air, according to research presented Saturday morning at the American...

A knowledge gap exists in the area of climate research: for decades, scientists have been asking themselves whether, and to what extent man-made aerosols, that is, dust particles suspended in the atmosphere, enlarge the cloud cover and thus curb climate warming. Research has made little or no progress on this issue. Two scientists from the Max Planck Institute for Meteorology in Hamburg (MPI-M) and the American National Oceanic and Atmospheric Administration (NOAA) report in the journal...

Ah, nothing like breathing clean coastal air, right? Think again. Chemists at UC San Diego have measured for the first time the impact that dirty smoke from ships cruising at sea and generating electricity in port can have on the air quality of coastal cities. The scientists report in this week's early online edition of the journal Proceedings of the National Academy of Sciences that the impact of dirty smoke from ships burning high-sulfur fuel can be substantial, on some days accounting for...

NASA scientists have determined the formation of clouds is affected by the lightness or darkness of air pollution particles. This also impacts Earth's climate. In a breakthrough study published Thursday in the online edition of Science, scientists explain why aerosols -- tiny particles suspended in air pollution and smoke -- sometimes stop clouds from forming and in other cases increase cloud cover. Clouds deliver water around the globe, and they also help regulate how much of the sun's...

NASA -- A NASA study found some clouds that form on tiny haze particles are not cooling the Earth as much as previously thought. These findings have implications for the ability to predict changes in climate.Andrew Ackerman, a scientist at NASA Ames Research Center, located in California's Silicon Valley, and his colleagues found, when the air over clouds is dry, polluted clouds hold less water and reflect less solar energy. Ackerman is the study's principal author.Contrary to expectations,...
