Republican-controlled Congress ordered destruction of vital sea-ice probe

November 5, 2017 — President Trump has been accused of deliberately obstructing research on global warming after it emerged that a critically important technique for investigating sea-ice cover at the poles faces being blocked.

This summer’s minimum is the eighth lowest on record and shrinking ice cap increasingly linked to extreme weather events around the world, say scientists

September 21, 2017 — The Arctic ice cap melted to hundreds of thousands of square miles below average this summer, according to data released late on Tuesday. Continue reading Melting Arctic ice cap falls to well below average

Arctic sea ice has dwindled to its summer minimum for 2017, with its smallest extent for the year clocking in at 4.64m square kilometres (sq km) on 13 September

September 21, 2017 — At 1.58m sq km below the 1981-2010 average, this puts 2017 as the eight lowest summer minimum in the satellite record, according to preliminary figures from the US Continue reading Arctic sea ice summer minimum in 2017 is eighth lowest on record

Arctic sea ice cover set to be second lowest ever recorded, data suggests

Satellite data shows ice was close to last year’s record low confirming a long-term downward trend towards ice-free Arctic summers

September 14, 2016 — Arctic sea ice cover could be confirmed within days as the second lowest ever recorded, the latest data suggests.  Continue reading Arctic sea ice cover set to be second lowest ever recorded, data suggests

A guest article by Florence Fetterer, principal investigator at the National Snow and Ice Data Centre (NSIDC) in the US

August 12, 2016 — Sea ice cover in the Arctic has undergone a widely reported decline in recent decades. The decrease has been greatest during summer, with sea ice extent reducing by around 12% per decade since the satellite record began in 1979.  Continue reading Piecing together the Arctic’s sea ice history back to 1850
