THE
SWINGING SEA ICE AREA: ARCTIC OCEAN AT A TIPPING POINT?
Via Facebook.Thanks Veli Albert Kallio and Sam Carana
The
Arctic Ocean's ice area has been seasonally all-time lowest most of
the days since the start of 2016.
Never
before the sea ice area has seen its current roller coaster rises and
collapses.
This
is due to wafer-thin film of ice forming over the sea which is then
pulverized and mixed into sea water by the first gusts of wind when
they come.
Then
the surface of sea freezes again, and the sea ice area skyrockets to
fall once again on this rollercoaster ride.
Currently
sea ice area is average, but this masks the sea being covered by a
thin film of ice, possibly wind blown snow flowing over cold sea
surface - which radar interprets as 'ice'.
The
wave action also pulverises ice and if anything one could start
calling this present rollercoaster without precedent as "tipping
point" on its clearest and most extreme manifestation.
