My Way News - The American "allergy" to global warming: Why?
My Way News reports: "The Arctic Ocean's summer ice cap has shrunk by half and is expected to essentially vanish by 2030 or 2040, the U.S. National Snow and Ice Data Center reported Sept. 15. Ashore, meanwhile, the Arctic tundra's permafrost is thawing and releasing methane, a powerful greenhouse gas. These changes will feed on themselves: Released methane leads to warmer skies, which will release more methane. Ice-free Arctic waters absorb more of the sun's heat than do reflective ice and snow, and so melt will beget melt. The frozen Arctic is a controller of Northern Hemisphere climate; an unfrozen one could upend age-old weather patterns across continents."
