The @financialtimes@flipboard.com rings in New York Climate Week with this front-page story: "US drivers face motor oil rationing as prices quadruple and supplies run dry" Yes, the only answer is to get off fossil fuels, all of them.

London has been London since it was Londinium some 2,000 years ago. It was built on clay soil then, and still is today. 5 successive heatwaves later, and that clay drying out so fast, it's leaving cracks all over: https://www.bloomberg.com/news/articles/2026-08-23/londoners-find-horrendous-cracks-in-homes-after-heat-waves @BloombergGreen@flipboard.com#climate #uk #london #energy

Just in case the "batteries and cold don't mix" trope is still alive:

A couple Austrians drive their 40 tonne electric truck to the northernmost point in Europe at -40°C, and back.

Not some kind of experimental truck. Off-the-shelf e-truck.

Huge since true.

"It costs just $33/MWh to transform daytime solar into dispatchable solar"

And no, that doesn't yet account for that storied Dunkelflaute. Then again, the typical gas LCOE doesn't account for Putin's whims or other geopolitical vagaries.

Perennial reminder: IKEA sells induction plates for $50.

Cap the gas line, put the induction plate on top of the gas stove, and avoid spewing carcinogens into your home.

Yes, you can also spend $5k on that beautiful high-end stove, while vying for that Michelin star.

The Iran War has once again led to a bout of what ECB board member Isabel Schnabel memorably dubbed 'fossilflation'. It's en vouge to talk about the solution as some massively complex undertaking.

*fossil energy crisis

And yes, that means pushing EVs (and cycling, for that matter) to get off oil (even) faster, and pushing renewables and batteries and heat pumps and home retrofits and industrial electrification and … to get off gas.

I'm no longer quite sure how to do this without just saying "Duh!"

Yes, getting people to pay the "green premium" is sometimes tough.

Guess what, the "security premium" is a lot higher.

The answer for both climate and security — and for economic competitiveness, too — is to get off fossil fuels.

Remember how EVs could never compete because batteries didn't allow them to go far enough, because they couldn't be charged fast enough, because they were too expensive...?

Funny how innovation works.

Love how @grist@journa.host writer @kateyoder@journa.host uses this essay on "How the Trump administration’s climate math doesn’t add up" as an excuse to slay the age-old climate-vs-the-economy trope.

Climate vs fossil-fueled profits? Of course.

Climate vs economy? Nope.

I'm old enough to remember when gas prices spiked 2x over a weekend, and then 10x by the end of the summer. That was 4 years ago, the last time a 'leader' blew a fuse.

Yes, then as now, the answer to fossilflation is to get off fossil fuels.

WSJ: "US Power-Plant Pollution Rose Sharply in 2025"

Leading cause: coal use up 15% after 20 years of downward trends, 'stay open' orders and all.

Let me go out on a limb and suggest another one, which will take months of study to confirm/reject: lack of/lax enforcement of (still) existing rules.
