what could go wrong?

according to the UK Mail, the Prime minister of the UK wants to release stuff into the atmosphere to stop global warming.

Experiments to reflect sunlight away from Earth will be given the green light by the Government within weeks, the Telegraph reports. Outdoor trials could include injecting aerosols into the atmosphere or brightening clouds to reflect sunshine.

The government's Advanced Research and Invention Agency (ARIA) has set aside £50 million for projects which will be announced in the coming weeks. Professor Mark Symes, programme director for ARIA, said there would be 'small controlled outdoor experiments on particular approaches'. 'We have strong requirements around the length of time experiments can run for and their reversibility and we won't be funding the release of any toxic substances to the environment,' he said. 

Hmmm.... sounds a lot like the Chemtrails conspiracy theories. 

Dr. Campbell is not amused.

I seem to remember that the massive explosion of Mt Pinatubo lowered the earth's temperature a couple years ago.

So I asked Grok and according to grok:

The 1991 Mount Pinatubo eruption had a significant but temporary cooling effect on global climate, counteracting global warming for a few years. The eruption injected about 15-20 million tons of sulfur dioxide into the stratosphere, forming sulfate aerosols that reflected sunlight and reduced global temperatures by approximately 0.5°C (0.9°F) for 1-2 years.

By 1993-1994, most aerosols had settled, and the cooling effect diminished. The eruption's impact on greenhouse gas concentrations was negligible, so it didn’t directly alter long-term global warming trends.

Grok then adds the global warming religion propaganda in their data: 

Data from NASA and climate models confirm this temporary cooling, with no lasting effect on the trajectory of anthropogenic climate change.

yes, those climate models. You know: GIGO: the problem being garbage in, garbage out. Given the collapse of trust in science thanks to the covid debacle, excuse me for being a bit cynical about this part. 

 

   the Pinatubo eruption was not the only time volcanoes caused the global temperature to drop. 

1815 the year without a summer:

and that might not have been as bad as the cold spell that helped the collapse of the Roman Empire:
