Projected total water demand may exceed total (natural) water supply before the end of the century in the western United States of America, Mediterranean regions, northern Africa, southern Africa, India, northern China, and southern Australia (red on map). Paper at: www.nature.com/articles/s41...

Great thread and links on global cities with high water insecurity by @thierryaaron.bsky.social (Lack of water = angry people)

Drought situation in Iran (and Iraq) looks bad. Major supply dam for Tehran may run dry before December. Another example of mid latitude regions drying around the globe coupled with natural climate variability + minimal preparation. www.aljazeera.com/news/2025/11... www.forbes.com/sites/sanamm...

It’s come to this. So sad for my once amazing organisation. That said, I still say 99% of people at the operational coalface put 110% every day into making Australia safer and more prosperous. I’ve never experienced more passion in a public service. Anywhere. New CEO literally starts tomorrow.

Shocking & inhumane in 2025 Australia. 65,000 First Nations’ households access electricity by prepaying with a national average of 49 disconnections per year *per household*. Disconnections double over 40°C. Overwhelming future Climate Risk #NCRA www.firstnationscleanenergy.org.au/national_inv...

Bugger.

Now there's an idea for Australia...

Insurance Australia Group (IAG) Severe Weather in a Changing Climate report www.iag.com.au/severe-weath... “The report complements Australia’s National Climate Risk Assessment (2025) … together with anticipated impacts for the finance & insurance industry.” Key Planning Recommendations are given

Solar, batteries, and a bunch of nice-looking techno-solutionist 'exponential' curves aren't actually resulting in the rapid elimination of fossil fuels, which is the exact thing we need to do to resolve the threat of a deadly overheating atmosphere will do a thread on this report later, when I can

The BoM insisting ‘the design only cost $4m’ is akin to pointing at your million dollar home and telling people “it only cost $10k (for the plans)”. #itsamilliondollarhome

Sinking (warming) air over Antarctica, resulting from the weakened polar vortex, has produced an ongoing period of negative AAO/SAM.

“Global warming projections over this century, based on full implementation of Nationally Determined Contributions (NDCs), are now 2.3-2.5°C, while those based on current policies are 2.8°C.” UNEP Emissions Gap Report 2025 www.unep.org/resources/em...

"The contract to build the {BoM} website, as opposed to its design, was originally signed to Accenture in August 2019 for $31.4 million... {this contract} has been amended 10 times ... and the full cost of the build has more than doubled to $78 million." www.thesaturdaypaper.com.au/news/2025/11...

This looks pretty exciting (for meteorologists) - global 100m observations of the atmosphere from cutting edge satellites. China leading the way right as NASA is being stripped for parts. www.cma.gov.cn/en/news/News...

If my doctor said that 2/3 of my tests shows I was going to die prematurely, I’d be quitting the beers and getting on the bike, ASAP! (In fact I probably just should anyway)

The next generations inherit the outcomes and impacts of climate decisions we make today. Will they look back and judge us harshly? Currently you’d say ‘yes’. But it’s not too late theconversation.com/climate-chan...

Bugger.

a lot of ppl worried about geoengineering, but the fact of the matter is we've been geoengineering the atmosphere with fossil fuels for decades, and I'm pretty sure that turned out fine, noting that I haven't checked yet

This is exciting; a forecast system that can do climate change and climate driver attribution, as well as re-run events in a future climate. Case Study: Australia’s Black summer fire and heat was enhanced by global heating, and far more extreme in future climate journals.ametsoc.org/view/journal...

In short, seize the day, stop the blame game, and do the right thing by the environment and wildlife, @albomp.bsky.social and @australianlabor.bsky.social! www.scimex.org/newsfeed/exp...

The United Nations World Meteorological Organization last night formally adopted a Youth Action Plan for weather and climate change. Our kids will inherit the worst impacts of emissions decisions made now. Announcement: wmo.int/media/news/w... And the actual Plan at: meetings.wmo.int/ec-79/_layou...

Let me get this straight... if you can demonstrate no net loss, you can destroy what you want? So if my wife and I have an extra kid, its ok to shoot someone? I'm not sure that's a good thing...

Chris Murphy: "There's a lot of history that has taken place in the East Wing & it was just destroyed without any conversation in the public, without any consent of Congress. It's absolutely illegal. That visual is powerful b/c you're watching destruction of the rule of law as those walls come down"

On the day of record heat and windstorms my links to BoM MetEye give a ‘page not found’. Brilliant.

Investor Group on Climate Change podcast on the National Climate Risk Assessment; labelling it "a significant step forward" for investors. While you may expect a focus on finance report, they say the infrastructure information is highly compelling for investors. podcasts.apple.com/au/podcast/a...

Insurance Council of Australia’s ‘Insurance Catastrophe Resilience Report’ shows $22.5 billion in insured losses over last 5 years — a 67% increase over previous 5-year period. Of the ~242,000 homes in severe/extreme flood risk, ~77% do NOT have flood cover insurancecouncil.com.au/wp-content/u...

Lucky enough tonight to see the dress rehearsal for an amazing jazz/imagery piece about climate - Acceptance does not mean Surrender - by Nat Bartsch. Performed live this Sunday at the Melbourne International Jazz Festival. And yes there is a bit of me in it… www.melbournejazz.com/events/monas...

“Growth rates of CO2 have tripled since the 1960s… From 2023 to 2024, the global average concentration of CO2 surged by 3.5 ppm, the largest increase since modern measurements started in 1957” wmo.int/news/media-c...

“The Government’s Strategic Examination of R&D (SERD) is failing vital discovery research” by focusing on business funded research. (e.g., we would never have created WiFi, but made a cheaper type of cable) Science and Technology Australia. scienceandtechnologyaustralia.org.au/serd-missing...

Excellent to see the G20 (which includes Australia) endorsing the idea of early warnings for all, as part of building weather and climate change resilience. Early warnings save lives. wmo.int/media/news/g...

This makes me very sad… especially as CSIRO’s Data61 has done some great work for the ACS. The move away from public good science is a sad one for Australia, right at the time we have never needed public good science more. www.theguardian.com/australia-ne...

The results challenge claims that the climate risk posed by an individual projects is negligible or cannot be quantified. 👉 theconversation.com/for-the...

If we told you that almost 500 people will die as a result of a project, would you still give it the green light? This new paper shows it's possible to calculate deaths (and other impacts) that would result from each new fossil fuel project being approved.

A reminder that the NCRA also did a global tipping points report, noting impacts upon Australia. The Antarctic and Greenland tipping points having particularly bad impacts upon sea level rise and our coastlines. Report at: www.csiro.au/en/news/all/...

The approval of new coal and gas follows the UNFCCC “SSP5 - Fossil Fueled Development” scenario. which means *at least* 2.7°C, but more likely ~4°C by 2100 The government’s NCRA has made it clear that even 2°C, let alone 3°C, is disastrous for our environment, society and massively expensive

NOAA has declared La Niña underway, though still right at their borderline. The BoM no longer has a La Niña warning system, as it fears misunderstanding and maladaption, but the old system would be at neutral. NOAA www.cpc.ncep.noaa.gov/products/ana... BoM www.bom.gov.au/climate/enso...

I will be helping give a webinar on the climate and hazard work underpinning the Australian National Climate Risk Assessment (NCRA), Monday 20 Oct - please register! events.teams.microsoft.com/event/b1585f...

Approving new coal mines assuming they will be profitable aligns Australia to IPCC's SSP5 'fossil fueled development' tajectory. SSP5 means *at least* 2.7C global heating, likely 4C, by 2100. The government's own National Climate Risk Assessment shows 3C is disasterous for every Australian.
