Satellite tracking shows how ships affect clouds and climate
By matching the movement of ships to the changes in clouds caused by their emissions, researchers have shown how strongly the two are connected.

Geoengineering versus a volcano
Major volcanic eruptions spew ash particles into the atmosphere, which reflect some of the Sun’s radiation back into space and cool the planet. But could this effect be intentionally recreated to fight climate change? A new paper in the AGU journal Geophysical Research Letters investigates.

Aerosol reductions could account for up to 40 percent of future Arctic sea ice loss
Anticipated declines in human-produced aerosols could have a significant effect on Arctic sea ice cover over the remainder of the 21st century, accounting for up to 40 percent of the decline in sea ice extent that could occur in the region by 2100, a new study shows.

Quality control of aerosol measurements filters out important readings
The hardworking AERONET (AErosol RObotic NETwork) instrument in Baengyeong, South Korea was having a rough day. Every 15 minutes, the telescope-like device pointed its barrel at the sun to record its light and measure how much was blocked by airborne particles, or aerosols. July 13, 2012 was an overcast day and the light absorbed by the clouds dominated the measurements. But then, just after 1 p.m., the clouds parted, the instrument looked up, and data was collected. Only no one saw it.

The National Academies Contemplate Geoengineering
This month at the National Academy of Sciences in Washington D.C., a 16-person ad hoc committee of scientists held its second meeting to discuss the practicality of various methods of purposefully changing Earth’s environment to combat climate change, sometimes called climate engineering or geoengineering. Convened purely for investigation and discussion rather than making recommendations, the group cast a wide net for ideas, even those they might ultimately reject as made- for-Hollywood only.
GeoSpace is a blog on Earth and space science, managed by AGU’s Public Information staff. The blog features posts by AGU writers and guest contributors on all sorts of relevant science topics, but with a focus on new research and geo and space sciences-related stories that are currently in the news.
