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
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.
Countergeoengineering Could Ease or Escalate Climate Tensions
Researchers systematically consider the feasibility and political implications of future strategies to counteract temperature-lowering solar geoengineering efforts.
A Date Under the Stars? Maybe Not with Aerosol Injection
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
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?
A climate engineering technique that lets more heat escape from the atmosphere could avoid water cycle suppression associated with other radiation management approaches.
