Title: Solar Geoengineering in Wrong Hands Could Wreak Climate Havoc,
Scientists Warn

Link: https://news.slashdot.org/story/25/11/05/1817...

Solar geoengineering could increase the ferocity of North Atlantic
hurricanes, cause the Amazon rainforest to die back and cause drought in
parts of Africa if deployed above only some parts of the planet by rogue
actors, a report has warned. The Guardian: However, if technology to block
the sun was used globally and in a coordinated way for a long period --
decades or even centuries -- there is strong evidence that it would lower the
global temperature, the review from the UK's Royal Society concluded. The
world is failing to halt the climate crisis and the researchers said that in
future, a judgment might need to be made between the risks of geoengineering
and the those of continued global heating, which is already costing lives and
livelihoods. The logistics of a large-scale geoengineering effort would be
daunting, the experts said, but the cost would be small relative to climate
action -- billions of dollars a year against trillions. The researchers
emphasised that geoengineering only masked the symptoms of the climate
crisis, and did not tackle the root cause -- the burning of fossil fuels.
Geoengineering could only complement the cutting of emissions, not replace
it, they said. If geoengineering was halted abruptly but emissions had not
been reduced, there would be a termination shock of rapidly rising
temperatures -- 1-2C within a couple of decades -- that would have severe
effects on people and ecosystems unable to rapidly adapt.
