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.
Researchers Quantify a Seeded Snowpack
In Idaho, three hour-long cloud-seeding events created the snow equivalent of about 282 Olympic-sized swimming pools’ worth of water.
Majority of YouTube Climate Videos Promote Nonconsensus Views
Search terms related to geoengineering solutions were almost exclusively about chemtrail conspiracy theories.
Study Will Examine Risks and Benefits of Climate Interventions
A National Academies committee is working to develop a research agenda for geoengineering strategies that reflect sunlight to cool Earth.
A New Road Map for Assessing the Effects of Solar Geoengineering
A special issue dedicated to modeling the impacts of stratospheric sulfur dioxide injections is a crucial step toward understanding the climate goals this intervention can—and cannot—achieve.
Island Building Alters Waters Leagues Away and for Years After
Quantifying the impacts of dredging through satellite remote sensing could serve as a valuable resource in future geopolitical disputes over contested waters.
Managing Uncertainties in Climate Engineering
Control theory and climate engineering meet in a new special issue of JGR: Atmospheres.
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.
