Record Antarctic temperatures fuel sea level worry

Friday - 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.

Antarctic sea ice records 'precipitous' fall

3 Jul 19 - The vast expanse of sea ice around Antarctica has suffered a “precipitous” fall since 2014, satellite data shows, and fell at a faster rate than seen in the Arctic.

HOT SPOT: Welcome to the fastest-heating place on Earth

3 Jul 19 - In the world’s most-northerly town, temperatures have risen by 4deg, having a devastating effect on homes, wildlife and even the cemetery. Will the rest of the planet heed its warning?

Arctic permafrost melting 70 years ahead of time

17 Jun 19 - Permafrost has begun thawing in the Canadian Arctic more than 70 years early because of climate change, according to new research.
