Bom: Why Australians are furious with their beloved weather website Nicknamed the Bom, the country's weather agency has been heavily criticised over a recent redesign.

Great BBC article on the psychology of why the BoM website update flopped. The site redesign revealed a ‘cultural blindness’ as to why Australians had a love for the old clunky site and the information it provided.

You can even request the library buys a book so win-win-win for author-library-you

I would love to calculate (somehow) the cost (in salary) of preparing DECRA applications vs funding received. Is it even net positive.

The fact that below average temps is notable is notable itself. I wouldn't mind some sun, though 😬

Had the opportunity to speak at the Senate Committee on Information Integrity on Climate Change and Energy yesterday. We had many questions, including from Malcolm Roberts (ironically). You can see how that turned out, below. Huge props to Alex Dunne, a PhD student in our team who also spoke.

Behold the atmospheric river rolling into California today.. a firehose of moisture wrapped into the rotation of an extratropical cyclone. 🌀🌧️🌧️🌧️

Yeah lack of specific details is a big giveaway, I like the horoscope analogy. Also, vocabulary that would make Merriam-Webster blush because they've told it to sound 'academic'.

Can everyone stop using weather terms as metaphors in non-weather publications. Do you know how many papers I have to scroll past titled "Lifting the Fog...." before I get to an actual paper on fog. Don't get me started on the compsci people ruining 'cloud' as a keyword search.

My parents heard a loud bang near Bairnsdale 💥

All the links to technical reports which I need for my research no longer work. This means that references to BoM research in published scientific articles are now outdated which is a problem for scientific transparency.

40 degrees of latitude long Atmospheric River on the horizon...what a beast. Thankfully, most of it is over the ocean (sorry North Island of NZ and the Pacific Islands)

A future dystopia where fossil fuel companies by carbon credits from assassins is a good Cli-Fi idea tho

This Northern California reservoir has pioneered a way to store more water After years of advocacy and experimentation, officials will celebrate the reservoir’s status as the nation’s first to get the go-ahead to adopt a flexible, forecast-based operations policy.

🌧️ Better #AtmosphericRiver forecasts 🤝🏽 smarter water storage

Lake Mendocino just became the first U.S. reservoir approved to use forecast-informed operations — a strategy pioneered by @cw3escripps.bsky.social Director Marty Ralph and partners to boost water supply while managing flood risk.

I've heard it called the Pho Express (Similar to the Pineapple Express Atmospheric River that starts in Hawaii)

Quantifying the regional to global climate impacts of individual fossil fuel projects to inform decision-making - npj Climate Action npj Climate Action - Quantifying the regional to global climate impacts of individual fossil fuel projects to inform decision-making

For so long, fossil fuel projects have said their contribution to climate change is "negligible".
Turns out that's wrong.
Our research in NPJ Climate Action proves it.
Every tonne of CO2 matters.

Screenshot of an ESS Open Archive preprint page. A green “Download PDF” button sits at top left. The title reads “Climate Experts’ Review of the DOE Climate Working Group Report.” Below are subject tags “Atmospheric Sciences” and “Climate Science,” followed by two listed authors. A “Preprint timeline” box shows “Submitted to ESS Open Archive” on 24 Sep 2025 and “Published in ESS Open Archive” on 29 Sep 2025. A citation block includes the DOI 10.22541/essoar.175745244.41950365/v2 and notes version v2 (processing). A right-side box says “Non-exclusive” and “No reuse.” A yellow banner at the bottom states: “This is a preprint and has not been peer reviewed. Data may be preliminary.”

Our comment to the DOE and EPA about the DOE Climate Working Group report is now posted on ESSOAR preprint server. It has a DOI and can now be cited!

Tell me how you really feel about my crafting skills 😳

I wasn't expecting them to be perfect but that's a little rude

Excuse me

On behalf of our 85+ experts, @andrewdessler.com and I submitted a minor update to the experts’ review as a comment on EPA’s proposed repeal of the Endangerment Finding. This version includes a new cover letter that walks through all the science EPA gets wrong.

and kangaroo!

For all those folk in Vic, you might be interested to know that the wild winds we've had last few days has resulted in the lowest 24hr period of brown coal generation on record 🎉

When scientists engage in data driven, but purposeful and meaningful activism it can have IMMEDIATE results. Climate scientists did an amazing job of pushing back on the DOE's nonsense and we're already seeing results from that effort. I need y'all to do MORE of this please! It is EFFECTIVE!

The merchants of doubt are back But this time, it's the U.S. government pushing doubt

On The Climate Brink, I write about the DOE report and our response.

It was a pleasure to be involved in this. Not a pleasure that it was necessary, but seeing around 80 scientists come together to defend scientific integrity, led brilliantly by Andrew, filled me with pride.

Was great to participate in this. Scientists were arguing up to the deadline about individual sentences, showing the difference in rigor when you care about accuracy, and how non-orthodoxy the “mainstream” actually is. But when comments are open for just 30 days it’s designed to be difficult.

DOE CWG STATEMENT (second paragraph of section 2.1.1, page 3): “Piao et al. (2020) noted that greening was even observable in the Arctic.” COMMENT: This statement implies that the Arctic greening signal was caused by elevated CO2 , however that is not the scientific consensus. Piao et al. (2020) attribute the greening trend in the Arctic predominantly to growing season length driven by warmer temperatures (see also Y. Zhang et al., 2022). Piao et al. (2020) also note that this positive impact of increasing temperatures appears to have weakened over the past four decades, “suggesting a possible saturation of future greening in response to warmer temperature” (see also comment on greenness trends related to Section 2.1.1, first sentence of Page 4). It is also important to put Arctic greening more broadly into the context of the carbon cycle and other impacts. While above-ground plants may have displayed more leaf area over the past decades, rising temperatures also thaw permafrost and drive accelerated decomposition in highly carbon rich soils (Turetsky et al., 2020), a process which is expected to accelerate as climate continues to warm (Miner et al., 2022). Thus even with Arctic greening, high latitude terrestrial systems may become net carbon sources to the atmosphere, causing an amplifying feedback (Braghiere et al., 2023). Other risks to the Arctic linked to higher CO2 levels and rising temperatures are not mentioned in this report (Virkkala et al., 2025). The Arctic is warming at a rate of 2 to 3 times the global average, leading to thawing of permanently frozen soils (permafrost), with downstream impacts including loss of structural support for buildings and subsidence, threatening communities, roads, runways, and other assets across Alaska (Manos et al., 2025; University of Alaska Fairbanks Institute of Northern Engineering US Army Corps of Engineers Alaska District & Laboratory, 2019).

Our comment on the DOE CWG report is done. It tips the scales at 439 pages, approx. 3x longer than the DOE report.
This is related to Brandolini's law: The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it.

Example: refuting one sentence.
