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.

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

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. Continue reading Russian tanker sails through Arctic without icebreaker for first time

Arctic sea ice could disappear even if world achieves climate target

Goal of limiting rise in average global temperatures to below 2°C may not prevent ice-free Arctic, scientists warn

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. Continue reading Arctic sea ice could disappear even if world achieves climate target

How disappearing sea ice has put Arctic ecosystem under threat

From algae to fish and polar bears, the loss of habitat caused by global warming is affecting the food chain

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 Continue reading How disappearing sea ice has put Arctic ecosystem under threat

New research calculates the impact of the average westerner’s carbon emissions to help people understand their own contribution to climate change

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

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

Arctic sea ice crashes to record low for June

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.  Continue reading Arctic sea ice crashes to record low for June

Pacific Ocean behind recent Antarctic sea ice growth

Scientists have long been searching for an explanation for the contrasting fortunes of sea ice at the Earth’s poles. 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.  Continue reading Pacific Ocean behind recent Antarctic sea ice growth
