You might think that the mayor of Yellowknife, the capital of Canada's vast Northwest Territories, would be a fan of giant pickups.

Nope. He's disgusted by car bloat.

On Sunday, #Zürich residents voted 52.8% in favor of increasing parking fees for cars according to weight.

The owner of a BMW X2 (Diesel), which weighs 1,675 kilograms, will now pay equivalent of €717 Euros per year to park on a public street. (Before, about €321.)

Under the UNFCC Canada is not responsible for the downstream combustion emissions of the fossil fuels we export. So we conveniently ignore them (as in Ksi Lisims Assessment and BC and fed announcements today), though those GHGs are more than Canada's territorial emissions to the global atmosphere.

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

DOE's embarrassment of a "climate science" report is 150 pages where as this response from the scientific community is 500.

My take: It takes much more effort to refute nonsense than it does to generate it, a tax on the time of all who care about fact and accuracy

The Department of Energy hired five academics to raise doubts about climate change. 85+ climate experts (organized by @andrewdessler.com) reviewed their report. Our conclusion, detailed in 450 pages of analysis: it is biased, full of errors, and not fit to inform policy making.

It’s over 1,000km from Berlin to Paris

There’s now a direct daytime train between them, that takes 8 hours and costs just €59. Leave at 10am, arrive 6pm.

And… it’s just 1% the carbon emissions of the equivalent flight

A point made insufficiently: nations of the world are lining up to poach US scientists and Harvard-bound students. They are not coming together to think about the hole in global science the Trump administration is creating. That's a problem.

Three issues with the term "decarbonized" oil:
i) It is silly. Oil contains carbon and emits CO2 when combusted.
ii) Doesn't even make sense for production emissions, because carbon capture and storage doesn't capture all emissions (can be <50%)
iii) Our trading partners know (i) and (ii)

The 2026 interim review isn’t fast enough to bring much-needed certainty to 🇨🇦 carbon markets.

The federal government should act decisively to modernize industrial carbon pricing

Industrial carbon pricing is Canada’s most impactful climate policy, capable of driving more emissions reductions than any other policy.
