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.

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...

Derailment warning as world faces threats to its ability to act on climate change We may have seriously underestimated the risks of climate change. This includes derailment risks. This does not mean we are doomed, and it certainly does not mean there is no point in trying to turn o...

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...

“One person- one vote” is the preserve of constitutional democracies, and USA is not that. Only the electoral college has the right to vote for US presidents; citizens just get whatever rights their state allows them. So I guess gerrymandering is probably not even illegal…

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!

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

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

As US climate data-gathering is gutted, Australian forecasting is now at real risk For decades, Australia has relied on data from US satellites, floats and monitoring programs. Planned deep cuts put Australian forecasting at risk

Our piece in @theconversation.com today:

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.

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?

Screenshot showing a variability of different climate-related graphics for different United States climate change indicators

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.

Line graph time series of 2025's daily global sea ice extent in red shading compared to each year from 1979 to 2024 using shades of purple to white for each line. There is substantial interannual and daily variability. Seasonal cycles are visible. A disclaimer is shown, which states: Trends/variability in Arctic and Antarctic sea ice are affected by very different atmospheric/oceanic processes and opposite seasonality!

With both poles observing unusually low sea ice conditions, global sea ice extent is the 2nd lowest on record for today's date...
