This may be about the UK but has an excellent quote that could be squarely aimed at the Australian Government: ““Future generations will not judge governments by the ingenuity with which they justified expanding fossil fuel production,” the scientists wrote./2 ”

This is at the core of much misguided thinking and disinformation.
Rahmstorf: “Some people think we can wait and, when it gets too bad, then we reduce emissions People don’t realise that we can’t make it get better again. We can only prevent it from getting much worse.”
Likewise as a climate scientist who began in radio astronomy I can’t understand how such a central and iconic part of your science infrastructure could be lost to current and future generations. 😥
I've been off socials for 2 years, but have to speak up. Utter madness to defund this flagship institution of UK science + education. International research, UNESCO-level heritage, training physicists (inc. me in 2000), inspiring public w/ visitor centre and bluedot festival. We must #SaveJodrell

Why did Antarctica freeze millions of years before the Arctic? New research suggests the answer wasn't just climate... Slow-moving mantle waves lifted Antarctica high enough for glaciers to take hold. Once ice formed, powerful feedback loops did the rest. theconversation.com/why-antarcti...

The National Climate Risk Assessment was not just a science report, it was a report on existential risk commissioned by the very government that has subsequently ignored it. The corresponding government National Adaptation Plan appears to be a plan for a plan. We had such high hopes.
El Niño is here, which means it's time for me to dust off and refine my old collection of ENSO-related climate visualizations. Check out how much sea surface temperatures have already warmed this year across the equatorial tropical Pacific. Wow! Data from psl.noaa.gov/data/gridded...
Wicked Newspeak from a once leading nation in Antarctic affairs: “watering down of references to climate change at the request of the United States, which prefers to speak of sea ice loss or generic environmental changes.”

It’s been a good two weeks of Wordle. Wordle 1,807 2/6 🟨⬛⬛🟩🟩 🟩🟩🟩🟩🟩 Archive: May 19, 2026 Wordle 1,795 2/6 🟨⬛⬛🟨⬛ 🟩🟩🟩🟩🟩 Tied the Wordle Bot 8 times and beaten it 3 times. Maybe time to retire 😬
It’s worth reading this excellent thread, but if you don’t, this is a good take-home.
15/ We didn't dodge the worst case. We narrowed one route to it. Several others have gotten wider. But the worst case was never fixed. It's a function of what we do next. We can always take actions that make it less bad. That's the part the relief takes, and the doom takes, both miss.
ABC burying the lede: www.abc.net.au/news/2026-05... He says: "There's this recognition that on so many of these big challenges we are facing, it's not necessarily left versus right, it's actually vested interests and their stranglehold on the major parties versus the Australian people."

Call it a party or maybe just a nation-wide cohort of independents with ideas and integrity like @davidpocock.bsky.social - I reckon they’d scare the pants off both major parties (albeit LNP already look like Malcolm Fraser in Memphis, iykyk 😉).

How do we know old Antarctic ice is old? Got a few minutes? Atmospheric argon isotope dating: a process discovered last century here at UMN (Al Nier) & perfected by scientists at Princeton (Bender). This is COLDEX science funded by NSF and conducted in university communities nationwide.
The MYIC @millionyearice.bsky.social project by the Australian Antarctic Program is drilling an ice core to 3,000 metres depth in three-metre segments, and returning the cores in pristine condition to Hobart, Tasmania. Why? And how? Find out at aapp.shorthandstories.com/the-memory-of-ice
