All things Polar... OBE, FRGS, D.Sc (h.c), Back Award 2023. Arrived at 328.28ppm CO2. My point is at 64°37′30″S, 62°33′15″W.

🧪🌊The world's largest iceberg, A23a, which ran aground on the edge of the South Georgia continental shelf two months ago, has started to break up. Ten days ago a fragment calved from its SW corner and has drifted away rapidly eastwards. The fragment is itself immense, measuring 19 km in length.

We’ve just published the most detailed map yet of the landscape beneath Antarctica’s ice sheet (called Bedmap3), and we learnt some pretty cool facts about Antarctica that you can use to impress your pals. Ready? Graphic: Hamish Pritchard et al

This #PancakeDay here's our recipe for pancake ice: 🧊 Get some ice forming on the top of your water 🌊 Bump bits of ice together with small waves ♻️ This rounds their edges as they freeze! 🥞 Grow the disc edges with trapped frozen foam These pancakes will be up to 3m wide + 10m thick. Bon Appétit 👩‍🍳

The surface of the ocean is frozen, but in a layer of round patches that all tesselate together.

Friday ice update - #Arctic sea ice extent is currently the *lowest* on record (JAXA data)... • about 820,000 km² below the 2010s mean • about 1,300,000 km² below the 2000s mean • about 1,880,000 km² below the 1990s mean • about 2,340,000 km² below the 1980s mean Plots zacklabe.com/arctic-sea-i...

Line graph time series of 2024's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with white for the 1980s, green for the 1990s, blue for the 2000s, and purple for the 2010s. Thin white lines are also shown for each year from 2002 to 2022. 2024 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between October and January by looking at the decadal average line positions.

Looks like the next week will be very warm across nearly the entire Antarctic Ice Sheet with widespread 5-15 C temperature anomalies. Multiple atmospheric rivers in West and East Antarctica will contribute to the heat. Definitely concerning as well are within the melt season

Breaking news! November, 2024, came in at the second warmest in recorded history, at 1.62°C above the pre-industrial baseline. Starting in June, 2023, there have now been 18 consecutive months above the pre-2023 record high, likely the hottest string of 18 months in the last 120,000+ years.

1️⃣ Antarctic Bottom Water (AABW) is the densest water mass in the world ocean due to its high salinity & cold temperatures. Filling the abyss, it accounts for up to 40% of oceanic volume. It plays a vital role in moving cold water toward the equator and regulating global climate. Animation: NASA SVS

October 2024 data is now available for both Antarctic sea-ice thickness/volume (zacklabe.com/antarctic-se...) and global sea-ice volume (zacklabe.com/global-sea-i...) from GIOMAS Last month's global sea-ice volume was a record low for the month of October. This continues the stretch of new records

NOTE: Trends and variability in Arctic and Antarctic sea ice are affected by very different atmospheric/oceanic/ice processes and are in opposite seasons! Caution is advised for assessing any stati…

Summer UK temperatures have warmed faster than global average temperature. But the very hottest days have warmed 4x faster than the global average, especially in south-east England. Global warming is not "just" 1°C or 2°C. The effects of climate change are non-linear, especially for extremes.

Aw! Andy! We love this interview with Jane Francis (aka the BAS Boss) too. Iceworld is our podcast series about the amazing people who live and work in Antarctica - from polar scientists to plumbers. 🎧 You can find it on all good podcast platforms!

Have you ever wondered what it's like to collect fossils on Seymour Island. Or to direct the British Antarctic Survey ? I found this fantastic interview with Jane Francis and it's definitely worth a listen @bas.ac.uk audioboom.com/posts/846937...

Changes in the #PolarRegions will affect everyone. Understanding and predicting this change needs commitment and talent; and that needs a supportive and inclusive community. Wishing everyone a happy #PolarPride as part of a wider celebration of #DiversityInPolarScience 🐻‍❄️🐧🥶🏳️‍🌈
