In answer to the the poll question:  Musk envisions eventually 100 persons per ship — with 1,000 ships making the trip during the Earth-Mars rendezvous period every two years.  He figures a Mars population of one million is the minimum to be self-sustaining.

Good news. It is hoped that by the end of the 21st century millions of people will live and work in space. This will be a good insurance against disasters on Earth.

Sea ice extent on the Atlantic side of the #Arctic has reached a new all-time record low for the region (combined Barents-Kara-Greenland Seas). Each line shows one year from 1979 (purple) to 2017 (white). The previous record was just last year.

Map of Arctic wells by 2015 year. Well-seen absence of wells in the Kara Sea, the East Siberian Sea and the Chukchi Sea (major part of the Arctic shelf).

Consequently, all estimates of the stocks of frozen greenhouse gases in the Arctic are very inaccurate.
Pardon me but  am totally confused - Arctic wells? What exactly is referred to by this? A link to the origin of that map would help a lot.

Over the past two days, the gap between 2018 and the remaining years has only increased.

Miracles! At 16-00 in Khatanga already +29.1С.

This is the maximum value in the meteorological annals of Khatanga from 1928 until June 18 (June 18 2014 was +32.9С).

Let's wait for the maximum temperature value today in Khatanga (June record in Khatanga - June 18 2014 was +32.9С).

According ice extent in the Central Basin, June 2018 it stably comes first, with a big gap from the rest of the years since 2006.

Probably the record deficit of ice around Svalbard will get an unprecedented number of attacks of polar bears on people. Until the autumn minimum area of ice is still far away, and polar bears are already climbing into populated areas.

Fresh news:

Swede discovers polar bear stuck in Svalbard hotel

It is believed that the number of polar bears in Svalbard exceeds the number of local population (4 to 3 thousand)

The past spring is definitely warmer than the spring of 2017.

It is interesting that now the ice edge near Svalbard has already receded to the records in the pre-satellite records of August (since 1553!).

The position of the ice edge (the gray vertical bars) in August between Svalbard and Franz Josef Land for the period 1553–2012, given as the mean latitude within the sector 20–45°E (modified after Vinje 1999 and updated to summer 2012).

In the graph above, extremes are shown for the period from 1980 to 2000. So I looked at the maps of the Arctic ice near Svalbard after 2000 on the 3rd of June (the attached drawing).

It turns out that in fact in 2018 there is a record low ice area around Svalbard (as in the Bering Strait area). Only in 2016 there was a similar situation (although even then there was more ice around Svalbard).
