Live: Angus Taylor overwhelmingly wins Liberal leadership, Jane Hume voted deputy Angus Taylor has been chosen as the new Liberal leader after defeating Sussan Ley 34 votes to 17, with Jane Hume elected deputy. Follow live.

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

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.

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.

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?

(Apart from anything else, every climber I know is way too cheap to forfeit a $4k deposit for carrying their own trash out…)

Nepal to scrap 'failed' Mount Everest waste deposit scheme Under the scheme, climbers paid a $4,000 deposit that was returned if they brought 8kg of waste down the mountain.

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?

I dunno man, geologists are still a bit defensive about the whole Alfred Wegener thing…

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

Line graph time series of 2025's daily Arctic sea ice extent compared to each year from 1979 to 2024 as shown with thin lines in colors from purple to white. This graph is for Baffin Bay. There is large daily variability, but a long-term decreasing trend during all months of the year. A seasonal cycle is also visible in this region.

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.

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...

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.

Depends. The only alternative to for-profit academic publishers is to support non-profit institutional journals, as either editor or reviewer

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…?

What planting tomatoes shows us about climate change It can be hard to grasp the changes climate change is bringing. To see it in your own life, look at the shifting seasons.

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)

Thanks for the great interest in this; unfortunately the venue has cancelled at the last minute! Enjoy your lunchtime without sea ice… @antarctic.bsky.social @antarcticsciaus.bsky.social

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.

'Rotten' Australian university culture lashed in long-running senate inquiry Australia's universities are blighted by a "culture of consequence-free, rotten failure", a senate inquiry has found.

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...
