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

NASA research shows that ice-free summers are now imminent, posing a peril to us all

January 8, 2017 — Something is happening to the floating sea ice of the Arctic, other than the well-documented retreat in its surface coverage each summer. Scientists are finding that Arctic sea ice is Continue reading Thawing Arctic is turning oceans into graveyards

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 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

Sea-level rise ‘could last twice as long as human history’

Research warns of the long timescale of climate change impacts unless urgent action is taken to cut emissions drastically

March 5, 2016 — Huge sea-level rises caused by climate change will last far longer than the entire history of human civilisation to date, according to new research, unless the brief window of opportunity of the next few decades is used to cut carbon emissions drastically.

Why is 2016 smashing heat records

January and February have both broken temperature records. Karl Mathiesen examines how much is down to El Niño versus manmade climate change

March 4, 2016 — Yet another global heat record has been beaten. It appears January 2016 – the most abnormally hot month in history, according to NASA – will be comprehensively trounced once official figures come in for February.
