By 2050 a lot of Alaska's permafrost, a storehouse of carbon over time, could be gone, the NYT reports.

  • Per University of Alaska, Fairbanks researcher Vladimir Ramonovsky, permafrost temperatures have already risen by 3 degrees Celsius at depths of 65 feet "over decades" and temperatures closer to the surface have climbed by as much as 5 degrees Celsius at one location.
  • Researchers debate the extent to which the permafrost will thaw, when it will happen, and how much carbon dioxide is trapped in it, but the warming trend is already being tied to rising carbon emissions in the Alaskan tundra, indicating it may be "shifting from a sink, or storehouse, of carbon, to a net source," the NYT's Henry Fountain writes.
  • Why it matters: Those emissions could contribute to heat being trapped in the atmosphere and compound warming. Plus, thawing could cost Alaska's infrastructure — think buckling roads, shifting construction, and slumping land.

Facebook is rolling out a new policy that will prevent U.S. news publishers with "direct, meaningful ties" to political groups from claiming the news exemption within its political ads authorization process, executives tell Axios.

Why it matters: Since the 2016 election, reporters and researchers have uncovered over 1,200 instances in which political groups use websites disguised as local news outlets to push their point of view to Americans.
