What
is the current Arctic sea ice extent?
The data for yesterday’s
sea ice extent is now the lowest in the satellite record for the
date and below the 2000’s average
The anomalous #Arctic #seaice year continues... today's extent is now the lowest in the satellite record for the date (JAXA) Zack Labe UCI
This is from the National
Snow and Ice Data Center (NSIDC) – I am unsure of the date for
this.
How this squares with
this I am not quite sure.
I have included comments
from Torstein Viddal from his website.
As we all know it is sea
ice volume and thickness that really matters, not the extent.
Annual
average sea ice volume is still 3rd lowest on record, but could go
4th lowest during August.
Arctic
Sea Ice daily dose of melt–out statistics:
13,750
km³ (3rd lowest) is the annual average volume
18,205
km³ (3rd lowest) is the year–to–date average volume
9,933,836
km² (2nd lowest) is the annual average extent
11,791,705
km² (2nd lowest) is the year–to–date average extent
Annual
volume (or 365–day average) is ��3.1 km³/day,
��24/week, ��144/month, ��1,140/year,
��100/5year (+0.7%), ��2,341/10year
(–15%), ��7,770/20year (–36%), ��9,882/30year
(–42%)
Annual
extent is ��0.08k km²/day, ��2k/week,
��30k/month, ��152k/year, ��58k/5year
(–0.6%), ��368k/10year (–3.6%)

True
statements:
*
2017 sea ice volume was lowest on record.
*
August 2016 to July 2018 sea ice volume is lowest on record.
*
August 2015 to July 2018 sea ice volume is lowest on record.
Statistical
1–3–year linear decline trends suggest a 6–month ice–free
Arctic Ocean by 2021–26. ESAS and other peripheral seas receive
stronger sunshine for longer, and are also more exposed to waves and
other strong oceanic feedbacks, like loss of Arctic inversion and
stratification, so likely to go ice–free for the ½ year by
2020–25.
Methane
is already escaping from the ESAS seabed in massive amounts, yet the
volume of these releases is likely to pick up dramatically once
sunshine and ocean heat are no longer spent melting local sea ice.
If
we think of the Biosphere with all its millions of plant and animal
species as ‘Gaia’ or ‘Earth’, then it is obvious that She
wants human cities to be flooded, industrialism to cease and
civilisation to end already. For we have chosen a great many decades
ago that we want this to be our path. We excelled and collapsed.
Polluticians like Stoltenberg and Brundtland in Norway, NATO and the
UN were mere prophets of the clueless, mindless continuation of
growth without limits, or prophets of the Massive Collapse, as they
may be known for posterity. After the collapse.
And
She is not indifferent to when She wants these cities all over the
world to be flooded. They need to flood ASAP, so She can live. Our
global industrial civilisation can only be compared to the comets
that wiped out almost the entire Biosphere millions of years ago. And
the Siberian Traps and the methane.
It
needs to go and it needs to go fast. So that others can live. There
will be a great dying of birds, trees, fish, insects and humans as
She heats up the planet to rid Herself of organised humanity. But
that dying is inevitable: It will happen sooner or later. The
prophets of limitless growth made sure of that. And when it has to
happen within a decade or a century, and all these species and
individuals, including humans, need to be flooded out, the advantages
of an Early Flood are plenty, and so we should embrace the melting
out of the Arctic and the wholesale rebuilding of the Biosphere.
With
modern technology we get to watch all of this play out from a front
row seat.

There
is now very little ice that is 1 meter thick or more
Compare
that with a month ago (1 July)
