Antarctica: 'ice vanishing at its fastest rate in recorded history.'
West Antarctic ice sheet collapse would mean 3.5m sea level rise.
(Greenland melt also at extraordinary levels, a calamity in terms of near-term sea level rise)

Melting rose dramatically from 1979 to 2001: an average of 48 gigatons annually per decade.
⚠️ The rate jumped 280% to 134 gigatons for 2001 to 2017.

Thwaites and Pine glaciers set to contribute to catastrophic sea level rise by 2035.

The vulnerable Larsen C ice shelf (northeast Antarctic Peninsula):
'Research increasingly suggests that foehn winds have a major effect on the ice shelf's melt rates in ways that could make it more prone to fracturing and potentially collapsing.'

Under the Antarctic ice, the colors and exuberance of marine life are 'reminiscent of tropical coral reefs.'
But will much survive as climate change disrupts today's stable environment with radical warming?

The world’s largest ice shelf - the Ross Ice Shelf - is the size of France and several hundred metres thick.
It's a vital natural barrier providing stability to the West Antarctic Ice Sheet.
⚠️ It's melting 10 times faster than expected. ⚠️

Even if Antarctic glaciers don't collapse in the next few decades, sea level rise will begin to wreck megacities by 2035. The faster the melting, the more severe the damage.

Ice loss is accelerating:
🔺Antarctica: Earth's biggest reserve of frozen, landlocked water
🔺West Antarctica's two biggest glaciers — Thwaites and Pine Island — are melting away five times faster now than they were at the beginning of a 1992 survey

Inevitable collapse.
Inevitable collapse.
If we stay under 1.5°C, largest ice shelves *might* not fail catastrophically. We'll, we're about to zoom over 2°C in the 2030s.
@BBC reporting on climate catastrophe is excellent - for fossil fuel corporations.

East Antarctica is the coldest spot on earth, long thought to be untouched by warming. But now the glaciers and ice shelves in this frigid region are showing signs of melting... e360.yale.edu/features/polar…
Precipitous decline:
Decreases in Antarctic sea ice extent have been 'so great that the yearly averages for 2017 and 2018 are the lowest in the entire 1979–2018 record, essentially wiping out the 35 y of overall ice extent increases in just a few years.'

Floating ice shelves along the edges of West Antarctica that slow the flow of its vast glaciers are under assault from all directions, and they're becoming more vulnerable to collapse. ⚠️

The fate of the world's coastal regions and the hundreds of millions of people who inhabit them depend on a block of ice atop West Antarctica on track to lift global oceans by 3 metres.
