A proposed solution to reverse the effects of global warming by spraying sulfate particles into Earth’s stratosphere could make matters much worse, climate researchers said on Thursday.

They said trying to cool off the planet by creating a kind of artificial sun block would delay the recovery of the Antarctic ozone hole by 30 to 70 years and create a new loss of Earth’s protective ozone layer over the Arctic.

“What our study shows is if you actually put a lot of sulfur into the atmosphere we get a larger ozone depletion than we had before,” said Simone Tilmes of the National Center for Atmospheric Research in Boulder, Colorado, whose research appears in the journal Science.
