Avi Lewis: Wildfires are getting more and more devastating because of global warming, which is primarily caused by the burning of fossil fuels. Trump won’t say that because he’s in the industry’s pocket.

West Virginia, Climate Budget Blindness
West Virginia is one of the most conservative American states and they strongly oppose efforts for the green transition. But they look away from the obvious unattributed costs of climate change. Not the flooding or property loss (they understand those costs)... It's The National Guard. We are going to use them more and more along with the coast guard and we already use primary branches of the military for backup of civilian operations. This is expensive and pulls people from jobs in the real economy. That backup will be needed more and more. And what is the hidden financial cancer inextricably tied to these events? Insurance. The United States government and states underwrite over $2.1 Trillion dollars of just flood/fire insurance. And what insurance won't cover, FEMA (or it's replacement) will. The taxpayers are on the hook for EVERYTHING.

Aral Seabed Carbon Source
Grist: "The Aral Sea isn’t just an ecological nightmare—it’s a carbon bomb."
Most of this inland sea sitting between Kazakhstan + Uzbekistan is a dry lakebed the size of Ireland. It dried out largely because for the past 60 years humans have bled it nearly dry irrigating cotton. "Its loss has long been seen as an ecological and humanitarian problem, but new research shows that it has also been a significant driver of climate change." The explanation is that when nearly any body of water is full and works as it should, organic matter collects on the bottom, where it remains trapped, often for centuries or even millennia.
Rafael Marcé, a research scientist in Spain, is the lead author of the paper which was published [this wk] in the journal Science. "The Aral Sea has left behind a timeline of sorts." The edges dried out decades back, while some areas were wet until just a few years ago. Cores were drilled along that gradation, allowing them to reconstruct that 748 M tonnes [Mt] of carbon had already released, equal to 3 times the annual emissions by Spain.
'At the beginning it goes pretty fast, then it decays slowly,' said Marcé, noting that about half of the carbon dioxide is released in the first 15 years after a section of the lake is exposed. And nearly a fifth of emissions came from wind blowing sediment away, an aspect of drying that experts say hadn’t been adequately studied before.
Other areas around the world experiencing the "dry flux" phenomenon include "Lake Chad in western Africa, Bolivia’s Lake Poopó, and the Caspian Sea, the world’s largest inland body of water, expected to shrink by more than the entire area of the Aral Sea by century's end. Also the Salton Sea in California + Utah’s Great Salt Lake, which another recent study found is releasing over 4 Mt of CO2 annually.
This combined global carbon flux until now had not been incorporated into climate models. Clearly, this problem is figureoutable.

Superstrong El Niño
ClimateBrink: "The Strongest El Niño Ever."
This is from a substack post by Zeke Hausfather, who gets points just for his name. "With the July runs now in from 667 ensemble members across 14 different seasonal forecast models, it looks like this year’s El Niño is not only very likely to be the strongest event since reliable records began—it may end up the strongest by a truly mind-blowing margin."
The multi-model median for the event’s peak (measured as 'detrended' sea surface temperature anomalies in the Niño 3.4 region of the tropical Pacific) currently stands at 3.6ºC, roughly 0.8ºC hotter than the prior record of 2.75ºC set in 2015-16. "No event in a century and a half of observations has ever pushed meaningfully past 2.75ºC." The legendary 1877-78 event comes closest, in a statistical dead heat with 2015-16 (2.73ºC vs 2.75ºC, well within the uncertainty of 19th-century ship data)."
"The 2026 event is developing faster than 1997-98, the previous gold standard for explosive El Niño onsets." And unlike 2015 which started its year already warm from a precursor event, this one launched from genuinely La Niña-ish conditions in January.
"In a warming world, the raw Niño 3.4 anomaly risks conflating El Niño with the broader ocean warming trend." NOAA’s answer is the "Relative Oceanic Niño Index (RONI)," which subtracts the tropical-mean SST anomaly to isolate the ENSO signal.
Aggregating all the models together, Hausfather projects a ~91% chance of a record peak in Niño 3.4 terms and ~77% in RONI terms this year. Whichever way you slice the index, the forecast says the same thing: this is more likely than not to be the strongest El Niño ever observed.
Clearly, time to batten down the hatches. Just as clearly, time to aggressively address the weirding climate.

Science is for Scientists, Laws are for Politicians, REALITY is for ACTUARIES
This study should be frequently referenced. It's not scientists or think tanks or politicians. This study was commissioned by an INSURANCE company. Actuaries do their best to calculate reality (insurance liabilities). They need to know what damage to expect regardless of how the green transition goes. Please note the GDP losses in the developing world v Rich world. Someone is going to do something desperate (Geoengineering)

The new british pm Andy Burnham
It may be the most ironic thing in the world that yesterday i made a post on a different climate community asking about our progress and scotlands contribution to climate change and today when i look into our politics i find that yesterday andy burnham got himself into being PM and already plans to open TWO NEW OIL AND GAS FIELDS IN THE NORTH SEA…which th licenses for both of these sites was overturned last year by the scottish courts cus well nobodys stupid enough to think thats a good idea, ironically also was one of the enviromentally friendly mayors of manchester in 2017 so ig its on us for having hope hed use his brain and not let big billionares get to his head…

Hydropower Transformers
CleanTechnica: "US Hydropower Faces Supply Chain Challenges With Large Power Transformers."
The National Laboratory of the Rockies (NLR) just released a report examining the U.S. supply chain for "large power transformers," or LPTs. "Large Power Transformer Supply Chain Gap Analysis and Domestic Content Strategies for Hydropower Rehabilitation focuses specifically on the unique challenges that hydropower facilities face when upgrading or replacing LPTs."
These are 'massive, custom-built devices [that] drastically increase the voltage of electricity generated by hydropower turbines for long-distance transmission.
There are 9 major issues, but sadly I have space for only a subset.
[1] U.S. LPT manufacturers rely 80% on imported raw materials like grain-oriented electrical steel + refined copper.
[2] Domestic manufacturing capabilities have grown in recent years but not enough to meet rising demand.
[3] The procurement timeline for a typical LPT (rated to handle 100 megavolt-amperes of electrical power) is approximately 2.5 to 3 years + up to 5 years for extra-high-voltage LPTs.
[4] Transformer costs have increased significantly since 2021, with prices rising approximately 80% in 2025. The cost of a single unit can be as high as $10 million.
[5] As these industries have been offshored over the last several decades, skilled workers have retired or moved to other industries. Thus, manufacturers and vendors of hydropower components struggle to find workers with more than 10 years of industry experience.
[6] Transport logistics are particularly complex for hydropower LPTs because many hydroelectric dams are difficult to reach due to rugged terrain or remote locations. There is a limited domestic fleet of specialized vehicles that can transport LPTs to these places, and routes require special permits for oversized loads.
I'll stop here, as the photo demonstrates this complexity all too well.
