Antarctica’s ‘Doomsday Glacier’ Just Got A Terrifying New Warning — Here’s What Scientists Are Saying The floating ice shelf that has been holding back Antarctica could break apart at any moment because that shelf is pinned to the seafloor by a single point. Credit: Breakpoint

We Now Have Early Warning Signal Of Ocean Current (AMOC) Collapse One of the most vital systems of ocean currents - needed to keep life in northern Europe stable - is at risk of collapse. And now we can predict when it’s going to happen. Credit: Alec Luhn ― New Scientist

New research: Doomsday Glacier ice shelf could ‘give way any day now’ The thin ice shelf that keeps it in place has been cracking for some time now, and the latest research strongly suggests that ice shelf could give way at any time in the next few months. How bad could it get? Credit: Dave Borlace ― Just Have a Think

There’s Something MUCH Bigger Than Yellowstone. And It Will Happen Again. There’s something so powerful it’s been linked to nearly every mass extinction in Earth’s history. Astonishingly, most people have never heard of it, a massive large igneous event. Credit: Maiya May ― PBS

Antarctica’s Collapse May Have Already Begun Antarctica is melting and one of its largest glaciers is collapsing from underneath. Thwaites could trigger a wider collapse of the full West Antarctic ice sheet, raising sea levels by 5 meters. Credit: Russell Arnott ― New Scientist

The Thwaites ‘Doomsday Glacier’ Is About To Collapse Thwaites is a massive glacier in Antarctica - the size of Florida. A key part of the glacier could break away any day now and trigger a 3 meter rise in sea levels, threatening the world. Credit: Alison George ― New Scientist

A Hidden Antarctic Tipping Point May Have Just Been Triggered Something unexpected and potentially irreversible is changing Antarctica and we finally know why. From sea level rise to the slowing of the AMOC, it will change our planet’s climate forever!! Credit: Maiya May ― PBS

Climate science may have made a BIG mistake! New research using the most comprehensive global dataset yet on biological nitrogen fixation suggests that one of the climate system’s most reassuring assumptions — the idea that rising CO₂ will significantly boost plant growth and help absorb our emissions — may have been significantly overstated. Plants will still absorb carbon, but the gap between what we emit and what nature can safely take up may be a lot wider than we once thought. Credit: Dave Borlace ― Just Have a Think

Is PERMAFROST the Climate Tipping Point of No Return? At 1.5°C scientists worry that melting arctic ice could lead to a sudden permafrost thaw and release of carbon dioxide (CO₂) and methane (CH₄) that forms a climate tipping point or feedback loop. Credit: Maiya May ― PBS
