US EditionScientists Warn Sun-Dimming Efforts Could Trigger Chaos
Two-thirds of climate scientists surveyed expect solar radiation management methods like aerosol injection to be used before 2100 amid insufficient emission cuts.
- New Scientist's survey of nearly 800 IPCC-contributing researchers found two-thirds expect large-scale solar geoengineering attempts before 2100, amid climate risks and governance concerns.
- Citing failed emissions cuts and rising impacts, experts say worsening global greenhouse gas emissions and climate effects push solar radiation modification toward consideration, Daniele Visioni and Shaun Fitzgerald note.
- Scientists describe methods such as stratospheric aerosol injection, marine cloud brightening and cirrus cloud thinning, warning of harms like ozone damage and up to 20 percent monsoon rainfall reduction.
- More than half of respondents flagged governance shortfalls as they warn deployment could be driven by a 'rogue actor' such as a private company, billionaire or nation state, with 20 percent opposing outdoor trials.
- Earlier this year the UK government provided £57 million via ARIA for solar geoengineering research, while philanthropic and investor funding expands, as the global research community seeks real-world data.

Anti-Aging, Acupuncture and Health NewsExclusive: 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...
