Yes folks ... time to leave behind those wonderful fantasies about how many angels can fit on the head of a pin ... or universes in a multiverse. So another dose for those who will inherit our mess.
Global warming may decimate the top 10 feet (3 meters) or more of perennially frozen soil across the Northern Hemisphere, altering ecosystems as well as damaging buildings and roads across Canada, Alaska, and Russia. New simulations from the National Center for Atmospheric Research (NCAR) show that over half of the area covered by this topmost layer of permafrost could thaw by 2050 and as much as 90 percent by 2100. Scientists expect the thawing to increase runoff to the Arctic Ocean and release vast amounts of carbon into the atmosphere.
