Can These Rocks Help Rein in Climate Change?

by Tim Hornyak 27 September 202227 September 2022

Spreading olivine on beaches could accelerate ocean uptake of carbon dioxide and potentially limit climate change. The concept and execution still face some scrutiny from scientists.

Iodine-Laden Desert Dust Is Eating at Ozone Pollution

by Jackie Rocheleau 28 February 202228 February 2022

In a happy accident, scientists found a potential solution to an atmospheric chemistry mystery. Their findings could be a missing piece in the iodine cycle and in atmospheric models.

Improving Models for Solar Climate Intervention Research

by S. Eastham, S. Doherty, D. Keith, J. H. Richter and L. Xia 19 March 20213 February 2022

Modern climate models were designed to simulate natural systems and changes mainly due to atmospheric carbon dioxide, rather than to predict effects of deliberate climate interventions.

Tailoring Aerosol Injections to Achieve Desired Climate Effects

by Terri Cook 16 April 20186 July 2022

Two-dimensional simulations of sulfate aerosol injections suggest that solar geoengineering projects can be customized to maximize solar reflection and help achieve potential climate objectives.

A Date Under the Stars? Maybe Not with Aerosol Injection

by S. McQuate 14 December 20163 February 2022

Injecting aerosols into the atmosphere on purpose could help cool Earth, but new research shows that it could also make the night sky brighter and negatively affect human health.

Aerosols Make Cumulus Clouds Brighter but Shorter Lived

by David Shultz 10 February 20163 February 2022

Computer simulations show that although adding aerosol particles to clouds can make them more reflective, the cooling effect from clouds is largely counterbalanced by a reduction in overall cloud cover.

Could Thinning of High Clouds Combat Climate Change?

by Sarah Stanley 1 February 20163 February 2022

A climate engineering technique that lets more heat escape from the atmosphere could avoid water cycle suppression associated with other radiation management approaches.
