  The Huffington Post: Sea Ice Melting As Arctic Temperature Rises

• “Beyond affecting the humans and wildlife that call the area home, the Arctic's warmer temperatures and decreases in permafrost, snow cover, glaciers and sea ice also have wide-ranging consequences for the physical and biological systems in other parts of the world.”

  The Washington Post: Arctic is warming, NOAA report says

• “Beyond affecting the humans and wildlife that call the area home, the Arctic's warmer temperatures and decreases in permafrost, snow cover, glaciers and sea ice also have wide-ranging consequences for the physical and biological systems in other parts of the world," NOAA Administrator Jane Lubchenco said in a statement.”

  The Wall Street Journal: Sea Ice Melting as Arctic Temperature Rises

• “Subsea permafrost is losing its ability to be an impermeable cap," Natalia Shakhova, a scientist at the University of Fairbanks, Alaska, said in a statement.”

  A Confession

• “Such sorting, together with longer term permafrost degradation, movement of soils on slopes, and displacement by moving compacted snow and ice, exerts strong forces on plant roots.”

• “Brad Arnold says: • There is an estimated 400 billion tons of methane trapped in permafrost ice. • An estimated 50% of surface permafrost will melt by 2050, and 90% by 2100. • Methane is more than 20 times as strong a greenhouse gas as CO2-the sudden release of just 35 billion tons of methane would be like doubling the CO2 in the air.”
