Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

January Polar Ice Extents Smallest on Record

Posted by feww on February 18, 2017

January Third Warmest Recorded Globally

Arctic Sea Ice Extent. January sea ice extent was 8.6 percent below the 1981-2010 – the smallest January sea ice extent since satellite records began in 1979.

Antarctic Sea Ice Extent. January sea ice extent was 22.8 percent below the 1981-2010 – the smallest January sea ice extent on record.

Global Temperatures

The globally averaged temperature over land and ocean surfaces for January 2017 was 0.88°C (1.58°F) above the 20th century average of 12.0°C (53.6°F). This was the third highest January temperature in the 1880–2017 record, behind 2016 (highest) and 2007 (second highest).

Global land surface temperature was also third highest for the month of January at 1.54°C (2.77°F) above the 20th century average of 2.8°C (37.0°F).

For the oceans, the globally-averaged temperature departure of +0.65°C (+1.17°F) from the 20th century average was the second highest on record for January, behind 2016.

FIRE-EARTH Alert: Low Polar Ice Extents

Posted by feww on January 8, 2017

‘Low sea ice extent continues in both poles’

Arctic sea ice extent for December 2016 averaged 12.10 million km², the second lowest December extent in the satellite record, NSDIC reported.

Sea ice in the Arctic and the Antarctic set record low extents every day in December, continuing the pattern that began in November. Warm atmospheric conditions persisted over the Arctic Ocean, notably in the far northern Atlantic and the northern Bering Sea. Air temperatures near the Antarctic sea ice edge were near average. For the year 2016, sea ice extent in both polar regions was at levels well below what is typical of the past several decades.

It was 20,000 km² more than the record December low in 2010, and 1.03 million km² less than below the long-term average (December 1981 to 2010).
