A perfect storm? Scientists ponder if #climate has entered a new erratic era

#RisingSurfaceTemperatures in the north #Atlantic exacerbated by #ElNiño and a drop in #AntarcticSeaIce are prompting fears for #ecosystems

Reviews! We need reviews!

We're updating & revising our staple climate myth rebuttals, including kind and gentle "at a glance" introductions. This week's item is to do with Antarctic sea ice, until recently a handy talking point for fake skeptics.

All new "At A Glance" sections feature a link to submit comments. Your thoughts and suggestions are more than welcome; just follow the link here to pitch in. Boosts help as well. Thanks!

"‘Everyone should be concerned’: Antarctic sea ice reaches lowest levels ever recorded - With the continent holding enough ice to raise sea levels by many metres if it was to melt, polar scientists are scrambling for answers - For 44 years, satellites have helped scientists track how much ice is floating on the ocean around Antarctica’s 18,000km coastline ... But across those four decades of satellite observations, there has never been less ice around the continent than there was last week ... “We are seeing less ice everywhere. It’s a circumpolar event. Hobbs and other scientists said the new record – the third time it’s been broken in six years – has started a scramble for answers among polar scientists.

The fate of #Antarctica – especially the ice on land – is important because the continent holds enough ice to raise sea levels by many metres if it was to melt ... “We are probably starting to see signs of significant warming and retreat of sea ice [in Antarctica]. To see it getting to these levels is definitely a concern because we have these potentially amplifying feedbacks.”

It's been a very #icy day, we discussed briefly the new #Antarctic #SeaIce minimum but there is not much to add to this post from @seaice

There really isn't any convincing trend in #AntarcticSeaIce, so we need to be careful with #Attribution

‘Extreme situation’: Antarctic sea ice hits record low

Sea ice helps protect glaciers and ice caps that would cause massive sea level rise when lost, scientists warn

'Recent study estimated West Antarctic Ice Sheet would be tipped into gradual collapse – and four metres of sea level rise with a global temperature rise as low as 1C, point already passed.'

'Antarctic sea ice extent fell to 1.91m sq km on 13 Feb, below previous record of 25 Feb 2022.'

Belgian research vessel was trapped in pack ice more than a year in Antarctic summer 125 years ago, in exactly same region Polarstern vessel is now sailing ice-free.
