One way to avoid the impacts of extreme weather on Antarctic research is to completely gut funding and logistical support for that research. Problem solved…

A significant part of me thinks we should move away from “scenario” based projections, and focus on warming levels (“at 2C warming the world will look like…”). The experiment protocols don’t necessarily need to change, just how we present the output

And meanwhile demanding that academics give up their time to review applications with a 2 week time frame…

🍺 In Hobart? Thirsty for #science? And beer? Check out "From Inner Workings to Icy Worlds", with our own Johannes Lohse spying on sea ice from space 6:30-8:30 pm, Wed 20 May Shambles Brewery, 222 Elizabeth St Get your ticket at pintofscience.com.au/event/from-i... @thatssciencetas.bsky.social

❄️🫀🐟 This week on TWICS: Antarctic sea ice, cardiovascular health & Tasmania’s sand flathead! Ahead of @pintofscienceau, we chat with Dr Johannes Lohse, Vimarsha Kodithuwakku & Rachel Breslin about the science behind their upcoming Hobart talks 🍻 #Tasmania #scicomm #stemmpodcast @EdgeRadio993FM

As a climate science communicator I’m told that it’s important to finish on a message of hope. But honestly, what does it say about us as a society that a month long illegal war has been a greater motivator of decarbonisation than decades of environmental degradation and threat to our own wellbeing?

The Atlantic Meridional Overturning Circulation (AMOC) isn’t going to collapse.

Wait, there’s a strategy..?

If you're in Hobart on Thursday 19 March, come to a public talk by Dr James Kirkham from @iccinet.bsky.social. The lunch-time talk will be at 12.30pm in the Aurora Lecture Theatre at the Insitute for Marine and Antarctic Studies @imas-utas.bsky.social in Salamanca.

It's going to be a difficult week for many of Australia's climate researchers. 🧪 I'll say more once the details of the proposed cuts are known but it's looking like Australia is going to heavily reduce our climate science capacity and capabilities. www.abc.net.au/news/2026-03...

Genuine question for any #arctic experts; does Lake Huron actually ice shelves? An ice shelf -typically 100s of meters thick and thousands of km in area - is the floating extension of a glacier or ice sheet. This sounds more like a chunk of lake ice that broke off. bbc.com/news/article...

Loss of summer land fast sea ice (or just “fast ice”) threatens adult Emperor Penguins, not just their chicks. Not kidding, l could do with a good news Antarctic story ….

Congratulations Australians! We have a brand new opposition leader to divide, whine, and offer no tangible policy! A completely fresh look from the previous policy-deficient whiner! #newbeginnings

Explaining to colleagues in Wellington why it’s important to consider SaFT* first when looking at extreme sea ice loss. (*SaFT = Stability at Freezing Temperature ; because we don’t need another dull 3-letter acronym!). Photo credit: Amelie Meyer)

But are you “beyond humble “?

🌊 An important new study led by ACEAS PhD researcher Annika Oetjens from @imas-utas.bsky.social at @utas.edu.au shows the Southern Ocean may be storing 40 to 60 per cent less carbon at certain depths than many climate models assume. Learn more ▶️ antarctic.org.au/southern-oce...

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.
