The White House released a report suggesting that a process to block out some sunlight coming into the atmosphere, "Stratospheric Aerosol Injections", (SAI) may be needed to curb the effects of climate change. This means limiting sunlight in an effort to cool the earth.
The report noted that "volcanic eruptions" are "natural analogs for SAI," as they shoot ash and particulate into the air, which does blot out the sun. The Biden administration said that it was promising.
A similar concept was floated on The Simpsons in an episode where Mr. Burns launched a plan to blot out the sun so that people would be forced to consume more energy.
SAI is part of the larger effort in the report to induce "solar radiation modification" (SRM).
