Reviewing Alex Steffen's Personal Climate Strategy Workshop
My thoughts on the most valuable climate foresight training I’ve taken
justusstewart.substack.com
Clearheaded, supportive review of my personal climate strategy workshop from former colleague (and recent alumnus) Justus Stewart.
Tbh, "left me sometimes struggling to keep up with the volume of concepts and tools" is a fair critique.

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.

Every politician loves a buyout program, despite evidence that the scale of climate risk and overvaluation of brittle assets make them unsuited to address the problem in any fiscally realistic scenario.

My sense is that China is using this oldie but goodie @rockymountviews.bsky.social playbook to destroy global oil demand. With subsidized EV technology, China can help 50+ emerging markets destroy 3-4 million barrels per day of oil demand by 2030.

Predatory delay on climate action is a central engine driving the fascism we see around us today.
When given the choice of accepting the evidence and shifting to a low-carbon economy, or undermining democracy itself, the Carbon Lobby went all in on Trump.

Some places face bigger risks than others, but no matter where we live, we're going to struggle to adapt to events unlike anything we've seen before.

I also suspect that the very idea that there are still ways to make this all work out in the end — that someone has, or will come up with a plan — contributes to the denial of discontinuity that stifles faster action and somewhat better outcomes.
