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.
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.
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.
Quantifying the impacts of dredging through satellite remote sensing could serve as a valuable resource in future geopolitical disputes over contested waters.
Control theory and climate engineering meet in a new special issue of JGR: Atmospheres.
Researchers systematically consider the feasibility and political implications of future strategies to counteract temperature-lowering solar geoengineering efforts.
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.
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.
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.
A climate engineering technique that lets more heat escape from the atmosphere could avoid water cycle suppression associated with other radiation management approaches.
