Bad news! What a shame and pseudoscience by the American Association for the Advancement of Science (AAAS)!
Because of the global reduction in air pollution, now we have to reflect the "sun's radiation back to space"? What a nonsense!
"Global warming [???] is bad news for polar bears, seals, and walruses; the Arctic sheets of seasonal sea ice they frequent have been on the decline for decades.
An ambitious idea seeks to intervene: sea ice thickening [???], where engineers drill through the ice and pump up ocean water to freeze on top in an attempt to delay summertime melting. If successful, the extra ice would also make the poles brighter, reflecting more of the sun’s radiation back to space [???] and lessening a dangerous climate feedback loop.
Like all geoengineering ideas, it’s controversial. But field trials have begun, and the first results are out: while pumping thickens ice, those gains don’t stick around. ..."
"A simple idea [??] underpins an audacious intervention to augment Arctic sea ice and slow the climate feedback loop accelerating its disappearance. Drill holes through a floe, pump seawater onto its surface, and let the cold do the rest. The first results from two field tests show the technique can thicken the ice. But they also show those gains don’t last. ..."
Artificially engineered sea ice grows—but tests are too small to combat melting "First Arctic trials show pumped seawater can bulk up ice, but results aren’t lasting—and may not scale"
