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.

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!

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.

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.

One of the best climate science comms jobs around, helping journalists explain how climate change has influenced extreme weather events, working with a top bunch of scientists at @wwattribution.bsky.social including @frediotto.bsky.social. London based, closes 5 Sep

Geographic biases in the AI alt text generator in Powerpoint #AIfails

Instead of regurgitating the bromide that LLMs are just "autocomplete on steroids" (even by people who know better), maybe we can actually engage in some public education. The problem with genAI is better expressed through a classic computer science concept, known as SYMBOL GROUNDING. 🧵

A global effort by climate scientists to respond to the scientific flaws of the DOE climate report, which Andrew is leading. A couple of Aussies involved.

I'd like list a couple pet peeves of mine that regular folks & professional mets have done this #hurricane season that is poor form: (1) Naming storms before they are actually named. (2) Sharing deterministic model forecasts (including AI models) beyond 5-7 days. Allow me a mini-rant to explain:🧵

Appreciating the irony of flash flooding in Perth during the #ClimateAdaptation2025 conference. Look at the length of that storm! The drains in the CBD did not cope.

There has been a strange shift away from "climate change" that I don't understand. I wrote an article for a respectable news org, and the editor changed all my uses of 'climate change' to 'global heating'. Scientists still call in climate change.

Horizontal [living] levees can reinforce traditional levees and reduce risks of waves overtopping levees by 30%...The main drawback is cost — more materials, more land used. But Taylor-Burns suggests costs of levee failure can be orders of magnitude greater. www.kneedeeptimes.org/new-metrics-...

New Research 💡 My summer students, Sophie and Emil, and I looked at future Atmospheric Rivers (ARs) over Australia in a warming world. Whether you define ARs using a present day or future moisture threshold does affect future projections. agupubs.onlinelibrary.wiley.com/doi/epdf/10....

The floods and droughts in Australia are fingerprints of a warming planet | Kimberley Reid

The forecast for Monday isn't looking good for NSW with the potential for more heavy rain. This is exactly what happened in March 2021, which you can read all about in our paper: agupubs.onlinelibrary.wiley.com/doi/full/10....

After the March 2021 floods, which had a similar pattern of unrelenting moist air over the east coast and a cut-off low, we quantified how likely these events may be in the future.

most effective ways to motivate climate action Interventions ✅target future thinking Ex. write a letter for a child to read in the future ✅why climate change matters to people & loved ones —inspire people to share articles & petitions ❌focus on individual carbon footprints, is not effective

A head in the sand approach stops working once the ocean is lapping at your neck. Unfortunately, the most vulnerable and least powerful will bear the consequences.

Where does Pope Leo stand on climate change? He believes it's time to move "from words to action" (he's right on that!) and has previously highlighted the actions the Vatican is taking to reduce its own emissions through solar panels and electric vehicles. Read more:

Major European institutes join race to save US science data. Thank goodness! www.nature.com/articles/d41...

The majority of people —56% in the US!—are worried about climate change, but not activated. Why not? Most feel helpless, hopeless, and don't know what to do. So more fear won't activate them. Rather, knowing what to do—and being invited to do it—will. Where to start? With a conversation today. 🧵

Really hoping I don't get penalised in the feasibility criteria of my DECRA for having a trip to the US in my application. I wrote it before all this.

We're looking for a postdoc to help understand and define the factors that make extreme rain effects more impactful, including clustering of heavy events or coincident heavy rain with strong winds. Is this you? Apply at jobs.anu.edu.au/jobs/postdoc...

Trump cuts to have ‘chilling effect’ on climate science and ‘degrade’ Australia’s ability to forecast weather - by @donnadlu.bsky.social www.theguardian.com/science/2025...

Multiple #AtmosphericRivers and low-pressure systems are forecast to impact the US West Coast this week into this weekend. The first AR will bring heavy rain and mountain snow to much of California. #CAwx. See our latest AR Outlook or more information: cw3e.ucsd.edu/cw3e-ar-upda....

AGU has joined a lawsuit challenging the firing of probationary employees at federal agencies. These actions weaken science, harm public health & the environment, and threaten national security. 🧵 #StandWithScience

Coral Sea surface temperatures in February were =4th hottest on record (since 1900) after January values were hottest on record. As warm ocean temperatures are TC fuel, this heat will have contributed to TC Alfred strength, longevity & ultimately rainfall totals BoM www.bom.gov.au/cgi-bin/clim...

When El Niño or La Niña doesn’t yield the west coast precip pattern you expected, look to the atmospheric rivers. They play by other “rules”…actually no rules yet. today.ucsd.edu/story/atmosp...

A less-common Eastern US Atmospheric River is currently causing deadly flooding and mudslides across multiple states. A high and low are helping to funnel warm and moist air from the Gulf of Mexico over the Eastern US.

In coordination with NOAA and the Air Force, CW3E's AR Reconnaissance field campaign has successfully carried out a sequence of 7 IOPs for this event, with flights from both Sacramento (C-130) and Honolulu (G-IV). Additional flights are planned this week.

Our study into why 2022 was so wet in Eastern Australia is now published (open access).This was a combined effort from 19 mostly ECRs to understand the meso, synoptic and planetary scale drivers of this remarkable year. journals.ametsoc.org/view/journal...

It is not too late to act on climate change because climate change is not pass/fail. Every faction of a degree matters and is worth fighting for. That's not propaganda or wishful thinking. It's evidence-based. Suggesting otherwise is as unscientific as climate denial, and just as damaging.

#AustralianOpen players were lucky the tournament didn't face any 40C days this year. But with #ClimateChange, it's becoming more likely. If Monday's forecast is right, Jan 2025 will have 2 days above 40C, which used to only occur during strong El Nino years.

Kermit, the Hurricane Hunter, is flying into #StormEowyn as part of a project to improve rainfall forecasts by collecting targeted observations during atmospheric rivers www.wcrp-climate.org/gpex-overview Meanwhile, I'll be writing my DECRA which aims to test whether this could work in Australia.

Reminder that US private investment into renewables and EVs was a record $71B in Q1 of 2024 - 40% higher than Q1 of 2023.

Two weeks later. This is exactly why La Nina thresholds need to be met for multiple weeks before declaring a La Nina.
