geoengineering the sky
Jun 23^rd, 2026 at 9:50am

Private firms are making plans to cool the planet by releasing reflective particles high into the atmosphere, an approach known as solar geoengineering or solar radiation modification (SRM).

While computer modelling shows the technology might work to offset global heating in the short term, it also points to risks for global weather systems, particularly in South and South-East Asia, where billions of people depend on the annual monsoon.

Currently, there is no international regulatory framework for SRM, and many scientists have called for its ban altogether.

SRM may refer to measures as simple as painting white roofs on houses.

But reflecting the Sun using tiny particles in the stratosphere, about 20 kilometres above Earth, is the largest-scale and most controversial SRM proposal.

Large eruptions in the Pacific sparked the idea.

When volcanoes blast millions of tonnes of sulphur dioxide into the sky, scientists have measured meaningful reductions in global temperature for years afterwards.

Andy Parker, who leads an NGO supporting SRM research in the developing world, said Australia's neighbours faced disproportionate climate risks whether the technology was used or not.

"There are risks if you use SRM [or] reject SRM and choose warming," he said.

I wonder which scenario was used for the climate risks? But he does use the CMIP sccenarios, with all their attendant problems. "Based on Physics" is highly uncertain when the models have to parametise clouds etc.

It would be an absolute disaster!
