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

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.

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)

🌧️ 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.
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.

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.

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!

essopenarchive.org/users/260056...
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 A yellow banner at the bottom states: “This is a preprint and has not been peer reviewed.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.”

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!

I've been getting requests from reporters about the disbanding of the DOE Climate Working Group. Here are some comments. More to come on my Substack (www.theclimatebrink.com).
The DOE Climate Working Group report was an absolute disaster from the beginning. It was created in secret with a hand-picked group of contrarians who do not represent any legitimate scientific position. The report ignored 99% of the scientific literature while employing selective data presentation, misrepresentation of scientific studies, misinterpretation of established science, speculative reasoning, and unsupported assumptions. Additionally, the group was clearly unprepared to meaningfully address the substantive critiques raised during the comment period. This disastrous episode should put to rest proposals for adversarial "red team-blue team" exercises in climate science. The field already undergoes extraordinary scrutiny and replication, making it among the most thoroughly validated scientific disciplines. While uncertainties exist in climate science, they are well-characterized and constrained—and these remaining uncertainties do not undermine the core findings that climate

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.
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).

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. 🧵

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.

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.
