(NOAA).What's new in 2015?
"Maximum sea ice extent on 25 February was 15 days earlier than average and the lowest value on record (1979-present). Minimum ice extent in September was the 4th lowest on record. Sea ice continues to be younger and thinner: in February and March 2015 there was twice as much first-year ice as there was 30 years ago.
Changes in sea ice alone are having profound effects on the marine ecosystem (fishes, walruses, primary production) and sea surface temperatures."
Highlights
"Air temperatures in all seasons between October 2014 and September 2015 exceeded 3°C above average over broad areas of the Arctic, while the annual average air temperature (+1.3°) over land was the highest since 1900. The 2nd lowest June snow cover extent on land continued a decrease that dates back to 1979, while river discharge from the great rivers of Eurasia and North America has increased during that time. Melting occurred over more than 50% of the Greenland Ice Sheet for the first time since the exceptional melting of 2012, and glaciers terminating in the ocean showed an increase in ice velocity and decrease in area."
"Walruses are negatively affected by loss of sea ice habitat but positively affected by reduced hunting pressure, while sea ice loss and rising temperatures in the Barents Sea are causing a poleward shift in fish communities. Widespread positive sea surface temperature and primary production anomalies occurred throughout the Arctic Ocean and adjacent seas as sea ice retreated in summer 2015."
Arctic Report Card 2015:
$ 5.3 Trillion spent globally on fossil fuel subsidies, will not subtract 100 billion metric tons of carbon that could be released from permafrost. The 300 billion metric ton carbon budget to burn at 12.1 tons per year is not combined with other natural & man made greenhouse gasses. The invention of A/C heat vacuums at Sanford along with progress toward carbon reducing chemicals are more likely to happen than a mass scale shift in human habits. Easier to develop technological solutions rather than alter the perception of freedom and rights to unlimited consumption. Understandably there is a fear of big government & communist principals dictating control over limited resources. Accidental De-population by pandemic during terror events, could buy time for condensed C.A.P. cities to re-structure more sustainable systems. If a crisis of extreme overheating does occur Geo-engineering methods will be conducted, if possible, in a last attempt to prolong life in some regions.
