Due process is ending after 250 years. The demise of the long-running pillar of democracy made our critic think of another thing: maybe the government should just kill everybody they don't like immediately and get it over with.

Couldn't agree more. The most in insidious denial lingo has long moved from outright climate change denial to arguments over 'critical' minerals, China(!), and the like. My own attempt on that front:

take on "Floodproofing Cities" Yes, we need to adapt to what's in store. No, that's not an excuse not to cut CO₂. Quite the opposite.

Really hot out today, so I could have sworn this one was a solar spill, or perhaps a heat pump implosion. Alas, just another gas spill. No fun.

I just want to add, since this is breaking containment, that this can't be made right. these people, each one a whole universe, are gone. there can only be justice for the perpetrators; public remorse & restitution; & reform to ensure future aid systems are more just and less prone to imperial whims

What was then Royal Dutch Shell detailed it in 1998: a scenario, whereby oil & gas go the way of tobacco, shunned from polite society within 25 years. Now their former headquarters stand in a city that has banned fossil fuel and meat ads. Bravo, Amsterdam!

I find that people often miss the leading role that oil price shocks have had in the global

- especially at the beginning. The 70's oil crises and a dislike of nuclear drove Danes to wind turbines, which is where it all began.

No climate policy — EV subsidies, CAFE standards, etc. — would have ever done as much to push the world off oil, as this war. The transition would have just been a lot slower, better planned, less disruptive.
