Arctic update - 11/01/2017

The latest from Sam Carana and Harold Hensell, with thanks.

Warm waters near Svalbard

Waters near Svalbard appear not to be cooling in October 2017. On average, sea surface temperatures (SST) at selected areas near Svalbard in October 2017 were 13°C or 23.3°F warmer than in October 1981-2011.

In October 1981-2011, SST gradually fell by more than 1°C, in line with the 
change in seasons (from 4.2°C or -39.5°F to 3.1°C or -37.6°F). In October 2017, 
SST went up and down between 16°C or 60.8°F and 17.1°C or 62.9°F, as the i
mage shows.


Methane 11 01 2017 

The Arctic Ocean excessive methane emissions. 

Methane emission highs were about 750 ppb for as far back as 800,000 years until around 1800. The pink is over 2000 ppb with a high of 2344 ppb in this image. 

The Arctic Ocean is a very dangerous place to see excessive methane emissions.…/sou…/iasi/m2/t1/D1/mr_ch4.074.gif

From Torstein Viddal
On the face of it, this stuff & this conference is incredibly boring! Yet, if you have a gene for philosophy & curiosity, it gets kinda interesting:
Corporations & nation states with their $$–eyed glance, view Arctic Sea Iceas a challenge, namely for shipping of consumer goods and for associated search & rescue. If it wasn’t for that darn ice, all of this economic activity would be a hell of a lot easier. The removal of sea ice opens up opportunity for new shipping lanes, harbours, container hubs etc. Profit margins may be increased, and geographically some previously ‘remote’ and ‘backward’ regions (Iceland, Greenland, Siberia) may see increased economic activity.
Climate Change or Global Warming are mostly never mentioned.
