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.

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

Climate change has thawed Arctic enough for $300m gas tanker to travel at record speed through northern sea route
August 24, 2017 — A Russian tanker has travelled through the northern sea route in record speed and without an icebreaker escort for the first time, highlighting how climate change is opening up the high Arctic.

March 6, 2017 — Arctic sea ice could vanish in summers this century even if governments achieve a core target for limiting global warming set by almost 200 countries, scientists have said.

March 4, 2017 — In a few days the Arctic’s beleaguered sea ice cover is likely to set another grim record. Its coverage is on course to be the lowest winter maximum extent ever observed since satellite

Scientists say it will be ice-free in summer in about 20 years under current climate action.

November 3, 2016 — The average westerner’s carbon emissions destroy 30 square metres of Arctic sea ice every year, according to new research.

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

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.

Photograph: NASA/Reuters From mid-June onwards, ice cover disappeared at an average rate of 29,000 miles a day, about 70% faster than the typical rate of ice loss, experts say
July 7, 2016 — The summer sea ice cover over the Arctic raced towards oblivion in June, crashing through previous records to reach a new all-time low.

While the Arctic has seen a rapid decline in sea ice extent in recent decades, the seas around Antarctica have slowly gained ice.
July 7, 2016 — Now, a new study suggests a natural shift from one state to another in the Pacific Ocean is responsible for the increase in Antarctic sea ice.
