Antarctic ice sheet folk, I'm looking for a Postdoctoral Fellow in Antarctic Ice Sheet Reconstruction [readvertised] for a 3.5yr appointment in Tasmania. Very flexible start date! Join our new team, figuring out what is happening and what may happen in East Antarctica. 1/4 ❄️

2️⃣ A new study led by @icecoldwill.bsky.social in @jgroceans.bsky.social looks at the ocean's role in limiting winter sea-ice growth. A metric called “Stability at Freezing Temperature” estimates how much heat the ocean must lose to the atmosphere for ice to form. ▶️ doi.org/10.1029/2025...

Sometimes I feel a little boring because I don’t travel so much these days. But there are some pretty spectacular adventures just 1.5 hours from #hobart … Images from a climb on the Candlestick, Tasman Peninsula. #climbing #tasmania

I’m currently getting “friendly reminders” to complete my assessments of FT applicants. I was thinking of submitting them them 2 months late and just doing 67% of the assessment. Because who am I to argue with the ARC standard…?

The global temperature was above average every single day of 2025. So what is average now?

Point of correction; people who pay tens of thousands of dollars to get dragged up Everest aren’t “climbers”, they’re unimaginative cashed-up glory seekers

This is ghastly! It will have an impact not just on USA but the many nations that benefit on NCAR’s climate modelling expertise

Wait, this isn’t all dicking around and I’m supposed to be taking this seriously?

the last @beeraquatic.bsky.social of 2025 is this Thursday! We don't think too much about the Indian Ocean here in Hobart, but it wields an influence on our weather. Find out how from @imas-utas.bsky.social Dr Helen Phillips. 6:30pm Nov 27th, Hobart Brewing Coy. #utas #hobart_events #scicomm

This year's #Arctic sea ice freeze-up is clearly the latest on record for the Baffin Bay region (located between Greenland and the Canadian Arctic Archipelago). The extent of ice cover is a record low for the date there. Data from @nsidc.bsky.social at nsidc.org/data/seaice_...

🧵 BY 2030: "The remaining carbon budget to limit global warming to 1.5°C is virtually exhausted and is equivalent to only four years of current emissions." — @pfriedling.bsky.social and @hausfath.bsky.social on the 2025 Global Carbon Budget in @carbonbrief.org ▶️ www.carbonbrief.org/analysis-fos...

Cat’s are b*stards; they puke on your carpet, wake you up at night, and then break your heart… Thanks so much Warren for all the purrs, the fluff and the many lessons. #adoptdontbuy #10liveshobart #cats

What's the future for Antarctic sea ice? Next Tuesday (11th November I'll be giving a free lunchtime talk at TMAG on @antarctic.bsky.social @imas-utas.bsky.social efforts to answer that very question. You can register here: url.au.m.mimecastprotect.com/s/UVHnCE8kD7... #hobart #utas #antarctica

We have ****ed the climate. Dressing this up as temporary overshoot is indefensible. But this does not mean we are doomed, & it certainly doesn't mean there is no point in trying to turn off the fossil fuel spigot. It's time to get real with climate risks. www.technosphere.earth/derailment-w...

Unsurprising but still dismal news; at over 45 years the satellite record of sea ice is one of our longest continuous climate records. Our experts at @antarctic.bsky.social are working to ensure consistency between the NSIDC record and alternative data sources

Wait, doesn’t this guy live in a palace and advocate for the economic burden to women of unrestrained birth rates…?

Spring is arriving here in Tasmania, which means it's time to think about planting tomatoes - we can learn a surprising amount about climate change just by looking at the seasons. 🌱🍅

Thankfully nowadays we no longer have unaccountable demagogues lying, stealing and starting wars…. (Oh yeah, and trawling through a line of trophy wives)

Shameless self-promotion here, but for anyone in Hobart tomorrow looking for a warm dry place to spend their lunch hour, I’m giving a (free!) public talk on Antarctic sea ice loss at TMAG. @utas.edu.au @imas-utas.bsky.social @antarctic.bsky.social

Last week the Australian government delivered an overwhelming National Climate Risk Assessment, and underwhelming carbon targets. Thankfully Dr Max Rintoul has some ideas on getting around that... @beeraquatic.bsky.social , 6:30pm Thursday 25th September, at Hobart brewing Coy. #hobart #imas_utas

I don’t love what’s happening in a lot of Australia’s universities, but given more than a decade of federal government under-funding research and higher education, it’s a bit rich for senate to quite so critical. www.abc.net.au/news/2025-09...

Are you in Hobart and looking for the perfect gift for Father’s Day on Sunday? I can’t help you with that, sorry. But, I am giving a talk to the Royal Society of Tasmania about climate change and Antarctica. All welcome! Sunday 7 September, 4pm, Geology Lecture Theatre, UTAS.

One protester said she loved the country, “Just not its people, its government, its policies, its cities, its suburbs, its taxes, its laws, its restaurants, its internet, its cyclists, its TV shows, its direction or its culture. Although I do quite like Yum Cha on a Sunday with the family”

Dr Scott Spillias last night at @beeraquatic.bsky.social , on whether AI fish will save the fish or crush our futures (maybe both?). Assisted by some friendly (and not so friendly) AI bots #hobart #marinescience #imas_utas

Will AI save the oceans, or drown us in a sea of big data? Fish-modeller Dr Scott Spillias has views on this, and he's spilling all @beeraquatic.bsky.social tomorrow! Come for the beer; stay for the science. 6:30pm 28th August, Hobart Brewing Coy

Beaker Street is here in Hobart! Time to party with people who have access to liquid nitrogen and ideas on how to use it! I’ll be around a lot of events; no liquid nitrogen but stop and ask me about frozen seawater… @beeraquatic.bsky.social #hobart #beakerstreet @imas-utas.bsky.social

Always great to see the beer/science communities combo @beeraquatic.bsky.social

Our piece in @theconversation.com today: As US climate data-gathering is gutted, Australian forecasting is now at real risk theconversation.com/as-us-climat... And it's not just Australia that will lose out. Forecasting all around the world will be set back decades if these cuts go through.

“Push it to the depths!” The very words I ride by… #MTB #tokyo

Not really shocking given the current political situation, but another big blow as Antarctica’s climate change is ramping up

Q: What happens when #Antarctic summer sea ice hits record lows in 2017, 2022, 2023, 2024 and 2025? A: aapp.shorthandstories.com/a-world-with...

I'd like to introduce a new page on my website: U.S. climate indicator visuals (zacklabe.com/united-state...). I only have a few basic variables so far, but I will be expanding this summer to add a range of metrics (e.g., ecological). I welcome suggestions! Hope this is useful, especially nowadays.

With both poles observing unusually low sea ice conditions, global sea ice extent is the 2nd lowest on record for today's date... More sea ice graphics available at zacklabe.com/global-sea-i.... Data from @nsidc.bsky.social.

Incredible heat in the Mediteranean with sea sfc departures up to 7C (13 F) above normal! While +13F is not unusual for air temps, for large water bodies it's ludicrous. Marine heateaves in the Med are now 3X more likely than the 1980s due to climate change - CC can explain 90% of this increase.

🛰️ "NSIDC's sea ice data is our number one heart rate monitor for the state of the planet’s ice. It’s our early warning system and tells us if the patient is about to flatline." — Dr Alex Fraser, AAPP sea-ice remote sensing scientist @utas.edu.au @nsidc.bsky.social 🌊 tinyurl.com/3vphpmzy

What's Antarctic sea ice ever done for us? Quite a lot! It cools the ocean, protects ice shelves, supports an irreplaceable ecosystem. Oh, and helps the ocean absorb $180 billion of carbon per year. Hopefully we can figure this out whilst there still is some summer sea ice... doi.org/10.1093/pnas...

Ok, let me be clear then. The climate is incredibly variable system that can’t be bottled in a test tube . It takes time/work to separate human effects from variability (working on it!) If we get it wrong - cry wolf - that’ll just fuel the deniers.

Been in Cairns all week for the Australian Meteorological and Oceanographic Society conference. Great to catch up with colleagues old and new (and nicely-timed to avoid Hobart’s cold spell!) But I have never been to a conference with such a palpable sense of despair.

Obviously I have skin in this game- being an Australian govt-funded Antarctic scientist and all - but this rolling short-term funding model threatens a world leading concentration of experts at a time when Antarctica is changing faster than govt policy…

Awesome news for the Antarctic research community! AAD has some well-publicised issues in the last few years, but if anyone can turn the ship around it’s Nerilie!

There’s a lot going on right now I know, but we’ll be dealing with the impacts of Antarctic climate change long after Trump, Putin and Netanyahu are gone

🦭 Seabirds and SciComm: An Immersive Fieldwork Extravaganza 🐧 Join Dr Olly Dove, zoologist and science communicator, as she shares her thrilling adventures in seabird fieldwork. From penguin fleas to shearwater vomit - Olly’s stories are as wild as they are informative. Don’t miss our May event!

My moonboot, puppet, and I are very excited to share that we’ll be giving a free public talk in two weeks’ time on Thursday 29th May at 6.30pm at Hobart Brewing Company 🌝 Have some fabulous humans helping me make it a fun night so hope to see some of your lovely faces there! 🐥 🍻

Ok, I admit it, I sometimes put a spoon in the fork drawer. I’ve also worn white after Labor Day. Sorry

Autumn in Derby. Tassie is awful; don’t come here! #mtb #tasmania

Punching down isn’t a replacement for viable policy

I get a little weary of the narrative that less than 50% of eligible voters chose Trump. As usual, about a 1/3 of citizens didn’t vote at all. US needs to accept that Trump isn’t the problem; he’s just a symptom of structural and cultural issues going back decades

New book!! 📕 Antarctica is intimately connected to the rest of our planet, affecting climate, ecosystems, cultures and society. Our new book draws together international experts to explore this influence, and to understand what humans are doing to Antarctica (1/n) www.routledge.com/Antarctica-a...

One thing to attract amazing talent in a time of disruption; I wonder how many will stay in Oz, once Trump’s gone and they’ve wrestled with the Australian Research Council 5 or 6 times…?

I’m pretty sure this policy was inspired by Adam Mackay’s movie “Don’t Look Up “
