Report: Increased greenhouse gases and aerosols have similar effects on rainfall

Although greenhouse gases and aerosols have very distinct properties, their effects on spatial patterns of rainfall change are surprisingly similar, according to new research from the University of Hawaii at Manoa's International Pacific Research Center (IPRC) and Scripps Institution of Oceanography. The study is published in the September 1 online issue of Nature Geoscience.

Aerosol geoengineering could make sky white instead of blue

Some scientists advocate pumping aerosols into the atmosphere to counter global warming by reflecting solar energy away.

Atmospheric geoengineering could make climate worse

One suggested method of countering man-made climate change, injecting sulfate particles into the stratosphere, could carry serious consequences, say scientists.

Air pollution leads to more extreme weather

Scientists say they've found the first clear evidence of the way increases in air pollution are affecting climate and weather - and the results don't look good.

Atmospheric aerosols slow global warming by a third

Airborne particles from volcanoes and the burning of fossil fuels have reflected enough sunlight to offset about a third of the current climate warming caused by carbon dioxide over the past decade, says the NOAA.

NASA calls off Glory launch at last minute

NASA this morning called off the launch of its Glory satellite, five minutes before takeoff. It's been postponed until tomorrow, with NASA citing unspecified technical issues.
