How Could Solar Climate Intervention Strategies Affect Agriculture?
Geoengineering approaches such as stratospheric aerosol injection hold the promise of limiting warming, but among the many potential risks and concerns, their impacts on agriculture remain largely unexplored.
Glacier Intervention Research Isn’t Just for Glaciologists
Prospects for mitigating sea level rise by slowing flows of glacial ice into the ocean are worthy of research, but this work must involve all rights holders and stakeholders.
Seemingly Simple Climate Adaptation Strategy Could Backfire
Reflecting sunlight can protect a neighborhood from scorching temperatures, but surrounding neighborhoods could suffer as a result.
Microbe Preferences Drive Ocean Carbon Pump
New research offers insight into how certain bacteria degrade organic matter in Earth’s oceans.
Cloud Brightening Could Have Unintended Effects in a Warming World
New research shows that though marine cloud brightening holds potential to temporarily reduce heat stress regionally, the technique has unpredictable and far-reaching outcomes.
Low-Level Clouds Disappear During a Solar Eclipse
Cumulus clouds rapidly dissipate as the land surface cools, a finding that has implications for Sun-obscuring geoengineering efforts.
Uncertainty Abounds in Seeding the Sky to Fight Climate Change
Some scientists have suggested injecting solid particles such as alumina, calcite, or even diamonds into the atmosphere to temporarily limit climate warming. But new research shows there are still big unknowns.
An Electrifying Approach to Carbon Capture
A new sodium-ion “battery” promises an environmentally friendly method of sequestering carbon in the ocean, but experts remain cautious.
Unexpected Consequences of Solar Geoengineering
Solar engineering is not a substitute for mitigation, and concerns about its risks and unintended impacts are supported by the recent discovery of overlooked atmospheric chemical feedback.
