Global (Arctic+Antarctic) record minimums, of the day of the year, seem
to be continuing to be broken,ie 03 May visually seems to have overtaken
02 May near parity .
I can only access Charctic every other day to put figures on it all.
30 April 2017 20.366 million sq km
30 April 2018 20.341 million sq km

02 May 2017 20.419 million
02 May 2018 20.418 million

Both "ends" of the planet continuing to break the record for least
sea-ice extent summed globally on-the-day of the satellite era of global
warming.
06 May 2018 sum of 20.602 million sq km from charctic
06 May 2017 (previous minimum on that day) 20.657

Did you see the link at the bottom of that page to the change in sea ice in the Bering Sea? The sea ice there seems to have gone completely in only 5 years. https://earthobservatory.nasa.gov/IO...w.php?id=92084

Temperatures north of 80N are also well above normal. http://ocean.dmi.dk/arctic/meant80n.uk.php

Yes, that is quite a dramatic change. It'll be interesting to see if it remains that way over the next 5 years.

Also check what happened there in February, particularly 22nd:
https://seaice.uni-bremen.de/databrowser/#day=22&month=1&year=2018&img={%22image%22:%22imag e-1%22,%22sensor%22:%22AMSR%22,%22type%22:%22visual% 22,%22region%22:%22Arctic%22}

Anything could happen in next 5 years. Changes in a particular area can
be extreme and somewhat unrelated to overall change. The excess ice off
E Greenland in the 60s persisted for a decade but, in 1969, I correctly
predicted that it would come to an end and that, in the early 70s, the
severe winter weather and associated heavy ice conditions would occur in
the Davis Strait and Labrador area instead.

Although I had that success fifty years ago, my prediction a little over
a decade ago of an ice-free Arctic by 2020 is looking somewhat unlikely
but I expect there'll be another record low maximum by then.

And considering Antarctic as well, going by
http://www.climate4you.com/Polar%20temperatures.htm
and rolling 3 year mean temp anomaly, latitude for mirror latitude
comparison North and South, both rolling-means rising, Arctic
satellite-record "all-time"
south pole (more consistent of the 2) highest since 2002 and probably
still rising like the north pole measure.

From Charctic and 07 May on-this-day, global sea-ice extent
2018 20.656 million sq km
2017 20.759 so less by 100,000 twice the decrement on 06 May

The of-the-day figure for global sea-ice extent deficit is still
increasing. I cannot access Charctic figures till tomorrow on someone
else's pc but graphically, so approximately from
https://sites.google.com/site/arctis...t_byyear_b.png
For 09 May 2018 about 230,000 sq km less than the satellite-era record
low of 09 May 2017, about 1% of the total on the day absent.
Pretty consistent lesser slope this year, compared to 2017, how bad will
it get, considering the lack of MYI in the Arctic.

FWIW 2018 seems to be tracking 2016 quite closely ATM, though not quite
as low as 2016.

As for global sea-ice , summation on the day, seems like 1979 was
similar low slope, poor ice increase over the month of April compared to
2018, going by the arctischepinguin plots
