What
is happening in the Arctic?
2309
ppb I can assure you that the satellite did not miss any of its
orbits.
They
could easily change their color scale so that we could have readings
of 2000, 2100, 2200 and so on, but they refuse to, because that would
be disclosing too much information to the public. They do not want
you to know how bad is now is.
Arctic
sea ice #'s
Annual
volume: 12,898 km³ (*record* low)
Year–to–date
average volume: 14,938 km³ (3rd lowest)
Annual
extent: 9,951,944 km² (2nd lowest)
Year–to–date
average extent: 12,121,879 km² (*record* low)
Annual
volume (or 365–day average) is +3.7 km³/day, +25/week, +116/month,
–633/year, –588/5year (–4.4%)
Annual
extent is –0.25k km²/day, –3k/week, +7k/month, +238k/year,
±0k/5year (±0%)
Arctic
sea ice extent has been lowest on record for the date for 13
consecutive days.

Statistical
1–3–year linear decline trends suggest a 6–month ice–free
Arctic Ocean by 2020–21.
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 2019–20.
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.
