We need not fear ancient methane timebombs

Tuesday - The Arctic is predicted to warm faster than anywhere else in the world this century, perhaps by as much as 7deg.

Earth's deepest ice canyon vulnerable to melting

27 Mar 20 - East Antarctic's Denman Canyon is the deepest land gorge on Earth, reaching 3500m below sea level. It's also filled top to bottom with ice which has a significant vulnerability to melting.

One summer cost Greenland 600 billion tonnes of ice

20 Mar 20 - Greenland lost 600 billion tonnes of ice last summer due to an exceptionally warm season, according to a new study.

Record Antarctic temperatures fuel sea level worry

21 Feb 20 - Sea levels might threaten coastal cities sooner than expected, scientists say, as ice loss speeds up and Antarctic temperatures rise.

Antarctic melt led to 3m sea level rise 120,000 years ago

14 Feb 20 - Mass melting of the West Antarctic ice sheet, driven by warmer ocean temperatures, was a major cause of extreme sea level rise more than 100,000 years ago, according to new research.

Antarctica logs hottest day on record

10 Feb 20 - Antarctica has logged its hottest temperature on record, with an Argentinian research station thermometer reading 18.3deg, beating the previous record by 0.8deg.

Rewilding the Arctic would be a mammoth task

31 Jan 20 - It would be a monumental task to start rewilding the Arctic, but the climate payoff could be mammoth.

What's driving the Antarctic meltdown?

14 Nov 19 - Along with warmer water eating away at Antarctic ice shelves from below, atmospheric rivers are causing trouble from above.

Melting glaciers reveal five islands in Arctic

23 Oct 19 - The Russian navy says it has discovered five new islands revealed by melting glaciers in the remote Arctic.

Antarctica shows 65,000 ‘meltwater lakes’

4 Oct 19 - Blue lakes have been forming in record numbers around the edges of the Antarctic ice sheet as warmer temperatures cause snow and ice to melt and collect in depressions on the surface.

Giant iceberg breaks off east Antarctica

2 Oct 19 - The calving of the 1636 sq km iceberg in Antarctica is not linked to climate change, scientists say, but could speed up further melting.

Changes turning Arctic into economic hotspot

26 Aug 19 - As melting ice opens Arctic shipping lanes and reveals incredible riches, the region is seen as a new geopolitical and economic asset, with the US, Russia, China and others wanting in.

Changing climate traumatises Greenlanders

14 Aug 19 - The climate crisis is causing unprecedented levels of stress and anxiety to people in Greenland who are struggling to reconcile the traumatic impact of global heating with their traditional way of...

Winds of change driving Antarctic ice melt

13 Aug 19 - Global warming is driving a shift in regional winds around the edges of Antarctica, and that's speeding up the meltdown of the West Antarctic Ice Sheet, new research shows.

DRONE ALONE: Ocean-going science in the southern seas

7 Aug 19 - New Zealand scientists have played a major role in the voyage of a wind-powered surface vehicle called a saildrone that is the first unmanned system to circumnavigate Antarctica.

Artificial snow could save the world, but there's a downside

6 Aug 19 - In theory, artificial snow could save the ice caps and limit sea level rise. The downside is that rescuing civilisation this way would sacrifice Antarctica.

Iceland leaves memorial to a glacier - and a global warning

24 Jul 19 - The first of Iceland’s 400 glaciers to be lost to the climate crisis will be remembered with a memorial plaque – and a sombre warning for the future.

Manmade Antarctic snows could save coastal cities

18 Jul 19 - Spraying trillions of tons of snow over west Antarctica could halt the ice sheet’s collapse and save coastal cities across the world from sea level rise, according to a new study.

Antarctic melting might become irreversible

11 Jul 19 - Antarctica faces a tipping point where glacial melting will accelerate and become irreversible even if global heating eases, research suggests.
