Antarctic Meltwater‐Stratification Feedback Is Less Pronounced Under High Climate Forcing Sub-surface ocean temperature increase due to additional Antarctic meltwater input weakens under strong climate warming Climate warming weakens vertical overturning in the Southern Ocean, making ...

We're on a roll this week! New paper from us: simulations from a coupled climate-ice sheet model show the meltwater stratification feedback is less pronounced under global warming

Nordic Seas Overturning Circulation strengthens as Atlantic Meridional Overturning Circulation weakens, new study 20/04/2026 –A new modelling study identifies a feedback mechanism suggesting that a strengthening of the Nordic Seas Overturning Circulation (NOC) could be a direct consequence of the Atlantic Meridio...

🆕 While the #AMOC is showing signs of slowing down, its Nordic branch #NOC is projected to strengthen. @sasha-roewer.bsky.social, @willemh.bsky.social, @rahmstorf.bsky.social et al have now identified a mechanism that links these seemingly opposing trends: www.pik-potsdam.de/en/news/late...

Nordic overturning increases as AMOC weakens in response to global warming Abstract. The Atlantic Meridional Overturning Circulation (AMOC) is weakening in response to global warming, while the Nordic Seas Overturning Circulation (NOC) is projected to strengthen. So far, the...

New paper published today that was led by some awesome students who did their master theses with us. We find an increase in Nordic seas overturning as the AMOC weakens due to global warming 🌊

Adam Morton Chris Bowen to begin Cop31 climate summit president's role remotely Chris Bowen's role as president for negotiations at the Cop31 climate summit in Turkey later this year will kick off remotely. With the fuel crisis raging and Bowen giving daily press conferences on the government's response, the climate change and energy minister said he would not fly to Berlin next week for the Petersberg Climate Dialogue, an annual meeting of representatives from about 40 countries. A spokesperson for the minister said he "considers his travel carefully" and would not fly for the meeting hosted by the German climate action ministry on Tuesday and Wednesday. "In this instance he will take advantage of the virtual attendance and continues to engage closely with all his international counterparts. Australia will also not be represented at ministerial level at the first global conference on transitioning away from fossil fuels in Colombia starting next Friday.

Australia's energy minister is skipping global meetings on accelerating the phase-out of fossil fuels because he has to stay in Australia to deal with the fallout from not phasing fossil fuels out fast enough.

Interesting example of motonormative double standards from Germany .

At present, fare evasion on public transport is a *crime* that can land you in prison, not just get you fines.

For illegal parking, however, that is not the case.

It's kind of wild. I had someone tell me that my personal boycott of these products won't achieve much and my only thought was "you really don't get how loathed this stuff is by the average person, huh?".

People hate this shit so much. Nobody's having fun. Even the AI people are getting tired of this. They're losing and they know it. Even with the ever-growing revenues of OpenAI and Anthropic, things feel weird and bad. Anthropic's services are also randomly broken or rate limited to hell. Cool!

Recent summers in Sydney are now twice as long as they were in the '60's, new research finds.

I've updated my El Niño forecast plume with the latest April data (ECMWF, NMME, CFSv2, Canadian models). Its now looking like it might end up giving 2015/2016 a run for its money in terms of strength, with a peak of ~2.6C in the ENSO3.4 region by end of year: dashboard.theclimate...

Taking this opportunity to remind everyone of this video:
My favourite is where it tried to kill someone by telling them to make chlorine gas.

I'm just .... I'm tired.

Stop pretending to be dumb: the Iran War is about Greater Israel, not “liberation” - The Shot There is a map. There is a plan. There are quotes. There is evidence, both historic and fresh.

Scientists invented a fake disease. AI told people it was real Bixonimania doesn’t exist except in a clutch of obviously bogus academic papers. So why did AI chatbots warn people about this fictional illness?

This is a fantastic example of how misinformation can be turbocharged with LLMs. This is then further fuelled by lazy scientists using these tools to do their reading for them. The future is bleak.

It's great that more people are cycling, but nothing will meaningfully change unless the infrastructure does. Painted bike gutters and fragmented, narrow bike lanes are not enough.

The environmental impact of AI: energy, water and emissions The AI boom is being sold as inevitable progress, but the real question is not whether artificial intelligence can do useful things in theory. It is who owns it, who profits from it, what it is mostly being used for, and who pays the environmental and political bill when the hype turns into microchip manufacturing plants, data centres, rising power demand, water stress, surveillance and attacks on democratic life. A Greenpeace Germany report released in 2025 warned that AI’s electricity demand, emissions, water use and raw material needs are all rising fast, and that AI data centre electricity demand could be 11 times higher in 2030 than in 2023 unless governments intervene. A February 2026 report backed by Beyond Fossil Fuels made the greenwashing problem even clearer, finding that 74% of industry claims about AI’s climate benefits were unproven and that it could not identify a single case where consumer generative AI systems such as ChatGPT, Gemini or Copilot were delivering material, verifiable and substantial emissions cuts.

"That is why the debate cannot be reduced to whether AI might do good one day, because the system being built right now is already redistributing power upwards while pushing environmental costs and information risks outwards"

It's impolite to call Musk a genocidal white nationalist because "civility" in American discourse functions not as a neutral procedural norm but as an asymmetric weapon to shield the powerful from accurate moral characterization while policing the tone of those who object.

I will never think of Elon Musk as anything other than a mass murderer for the USAID cuts. I’ve long felt he’s one of the most villainous people alive today, the real-life equivalent of a comically annoying and cruel supervillain

“BlueSky is dying” and the heat death of the universe approaches too. For now this will do fine

This is so, so well-articulated.

We could've phased out fossil fuels the gradual, smart and painless way starting in the 1990s

The fossil fuel industry decided we have to do it the painful, unfair and cruel way instead. because that gave them an extra few decades of super-profits

Paper Finds That Leading AI Chatbots Like ChatGPT and Claude Remain Incredibly Sycophantic, Resulting in Twisted Effects on Users A study found that sycophancy is pervasive among chatbots, and that bots are more likely than human peers to affirm a person's bad behavior.

A new study found that sycophancy is a pervasive function of leading chatbots, which are likely to give users bad/antisocial advice when asked about real-world interpersonal conflicts -- warping users' judgement and promoting dependence.

National Press Club platforming Israeli ambassador - knowing IDF killed 250+ journalists - for lunch chat. In the same week Israel admits doctoring Lebanese journalist image after murder. Disgraceful & dystopian yet somehow still shamelessly in full view, to be broadcast on ABC
