Remember the really low levels of #SeaIce in Antarctica last year? Records tumbling? For the first time, now we know: 1) how rare this sea ice loss was 2) if climate change made it more likely Spoiler: it was super rare; now it’s four times more likely. Buckle up for a 🧵⬇️

"Why does this even matter", you ask. Why is sea ice important? 🖤 It's white and reflects sunlight(!) 🍀 Sea ice is linked to the scale/timing of algae bloom 🐧 Which matters for krill + the whole food chain 💧 Those plants + plankton also sequester carbon in the ocean 🧵⬇️

So there you have it. It may sound like grim news, but it's also more evidence that the power to change things is still in our hands. 📰 Here's the full news story: buff.ly/4axf0fY 📝 And the link to Rachel Diamond's paper: buff.ly/3yranH7

The Annual DEFIANT Meeting is underway at @BAS_News in Cambridge! Thanks to all the scientists and staff who have made it a success so far. Can't wait to hear what's next!

What's going on with Antarctic sea ice? 🤔 BAS sea ice scientists Dr Caroline Holmes + Dr Jeremy Wilkinson are here with your briefing on: 🧊 context for the current lows 🌍 sea ice as part of global climate systems 📉 the science plan to investigate ➡️ bas.ac.uk/beyondtheice

Dr Caroline Holmes @BAS_News explains that the impacts of shrinking sea-ice may become evident as the season transitions to summer. Read more➡️bbc.co.uk/news/science-envir… #science #environment #Antarctica #climate

Sea ice is *spectacularly* low this year. But what's it like working on sea ice science - in the depths of Antarctic winter - while that's happening? Over to @RobbieMallett, who's in the field working on the @DefiantNerc project ⬇️ ow.ly/pfvm50PFPSB

Feeling the heat in Antarctica: the urgency of sea ice research - British Antarctic Survey

Dr Robbie Mallett is a sea ice scientist, currently over-wintering at Rothera Research Station in Antarctica as part of an eight-month research campaign for the NERC DEFIANT project. Robbie explains...

new study concludes extremes in all aspects of @Antarctic climate system are virtually certain to become more pronounced under climate change: new study feat. DEFIANT scientists @TomBracegirdle @oceans_and_ice @CHolmesClimate and Jeremy Wilkinson frontiersin.org/articles/10.…

There is increasing evidence that fossil-fuel burning, and consequential global heating of 1.1°C to date, has led to the increased occurrence and severity of...

You might have heard: we're missing an area of sea ice bigger than Greenland. "Antarctic sea ice varies a lot year-to-year, but even by Antarctic standards this is well outside the bounds of normality," say BAS experts @Dr_Gilbz + @CHolmesClimate ⬇️ theconversation.com/antarcti…

Antarctica is missing a chunk of sea ice bigger than Greenland – what’s going on?

Sea ice extent in July 2023 has been around 10% below last year’s record low for the month.

#Antarctic #seaice there's widespread discussion about the sea ice anomaly and what it means statistically and physically, and some good discussions, but I think some key graphs need showing *together* so here goes (1/15 🧵)

@DefiantNerc Very much enjoyed hearing about first field results and to discuss data analysis. Looking fwd to some international in person workshops befire too long.

We have our DEFIANT hybrid kick-off meeting this week, held at the Aurora Innovation centre @BAS_News. Great to see people in person finally!

good day getting together with the @DefiantNerc team today with a vECR (very early career researcher!) in tow. (I'm on mat leave- this was good use of a 'keeping in touch' day!)

Can’t wait to see the echograms over such heterogeneous surface typical of Antarctic sea ice. So many applications for our team analysing @JulienneStroeve’s KuKa radar data for future radar altimetry multi-frequency satellite applications @esa_cryosat #CRYSTAL @CopernicusData
