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.

Iron Fertilization Might Not Make Oceans Better Carbon Sinks

by S. Kelleher 5 February 20161 March 2023

New research suggests more iron during the last ice age did not mean more algae production in the equatorial Pacific, pointing to possible futility of a controversial geoengineering idea.

Could Thinning of High Clouds Combat Climate Change?

Sarah Stanley, Science Writer 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.

Volcanic Eruptions Steer Conversations on Climate Intervention

JoAnna Wendel, freelance science writer and illustrator by JoAnna Wendel 18 February 201518 November 2022

Studies of volcanoes, Earth's natural climate coolers, cause scientists to question the merits of methods that intend to slow down climate change by injecting the stratosphere with aerosols.
