Arctic Sea Ice Extent Record Low

The average monthly Arctic sea ice extent for the first half of this year was a record low among all the first halves going back to 1979. Second was 2018, 10,000 km² higher (0.01 Mkm²). At this pace it will lead to an annual low. 

June's SIE was 3.4% below May's. The average month year-to-date (YTD) has been 3.8% lower than last year's values. If either of those continues for the rest of the year they'd make this year a new annual record by about 0.12-0.14 Mkm² respectively. Even if the rest of the months of this year are identical to the corresponding months last year, Arctic SIE would tie 2016 for a record low. 

This seems to have snuck up out of nowhere.

In other numerology, Antarctic SIE in June was 3rd-lowest in the record, and the year-to-date average is 6th. 

UAH's global lower troposphere temperature for June was the 2nd lowest, after last year's. 

The Hadley Central England Temperature (HadCET) was 5th highest going back to 1659. The year-to-date average monthly temperature is also 5th lowest. Its graph is looking pretty dramatic:

   

The South Pole temperature was 21st highest out of 68 years. The year-to-date average is 13th highest of 69 years. As always things are kind of weird down there:
