Celebrating 99 years of Sir David Attenborough! Sir David continues to bring the beauty, and challenges, of Antarctica to peoples' homes and we cannot thank him enough for raising awareness for this amazing continent 💙🐧

#EarthDay is a great day to stop and reflect on the unique Antarctic environment. We would love to see some of your favourite Antarctic images. Here are a few of ours to start 🐧🧊🌍

🧪🌊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.

A driving force for change. This morning we met with Antarctic tour operators and scientists to discuss tourism to the continent and a potential framework for all Treaty Parties. Thank you to @hx-expeditions.bsky.social for hosting us and looking forward to continuing discussions 🐧

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?

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.

Today is #InternationalPolarBearDay 🐻‍❄ so it seems like a good day to give a shout out to everyone who lives and works in the #Arctic, and those who strive to understand, promote, and where needed, protect the vulnerable habitats of this majestic creature 🥶❄️😎

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.

🚨 Last month averaged the lowest #Antarctic sea ice extent on record for the month of November.

This was 1,710,000 km² below the 1981-2010 average. Data from NSIDC: nsidc.org/data/seaice_...

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.

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

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.

Maps showing warming for each UK county for typical summer days (left) and hottest days (right), with darker reds and faster warming for the hottest days especially in south-east England.
