Scientists Warn Sun-Dimming Efforts Could Trigger Chaos

Geoengineering: Assessing Risks in the Era of Planetary Security

As the effects of climate change intensify, interest in geoengineering approaches is ramping up. But these methods risk creating new ecological and security threats, undermining urgent systemic transitions.

Exclusive: Climate scientists expect attempts to dim the sun by 2100

An exclusive New Scientist survey of leading scientists reveals widespread concern that schemes to tweak Earth’s atmosphere could launch within decades in a risky bid to cool the planet

Scientists say dimming the sun could spark global chaos

Scientists are taking the once-radical concept of dimming the sun through stratospheric aerosol injection (SAI) seriously, but a Columbia University team warns that reality is far messier than models suggest. Their study reveals how physical, geopolitical, and economic constraints could derail even the best-intentioned attempts to cool the planet. From unpredictable monsoon disruptions to material shortages and optical inefficiencies, every step

Scientists propose dimming Sun to curb climate change? New study says it’s dangerous

Climate change is wreaking havoc through severe weather patterns, including wildfires, heatwaves, droughts and floods being observed across the globe resulting in loss of life and inflicting...

How Hard Is It to Dim the Sun?

Solar radiation management is gaining traction as a climate intervention—but new research warns that real-world constraints make it riskier and more uncertain than most models suggest.

The aerosol dilemma: How fighting pollution affects climate change

In a Q&A, Jessica Seddon of the Yale Jackson School of Global Affairs explains the need to integrate climate and air-quality policies.
