Geophysically, there are 3 pillars to climate stabilization:

1. Emitting fewer greenhouse gasses. Need to do that more than ever, but we are now in overshoot so…

2. Actively remove greenhouse gasses from atmosphere. Will need to do that, but land use and dirty energy trends away from net negative. Also, it’s a 100 year project once started.

3. Shade Earth. Not regions, The whole globe. There are two ways to do that:

a. Stratospheric aerosols b. Planetary sunshades in space, at Sun-Earth L1.

That’s the whole solution space, conceptually. As long as we continue to fail within that space, we will suffer compounding effects of unmitigated climate change.

Worth noting that aluminum is the most abundant metal of the Moon’s highland geography, thus excellent for bootstrapping beyond Earth.

This lowers p(doom) for me.

It makes sense that reinforcement learning on reasoning about coherent principles should bias toward principled action in real situations.

Probably also illuminates moral interpretability.

Philosophically, this looks like breaking the training data limit in the same way that humans do: by using an internally consistent view of the world to imagine new scenarios and integrate them into an updated worldview.

Feels like 1999 all over again. This time, I think it really is different.

It is insane that the Paris agreement requires a centered 20-year running mean of global surface temperature to define global warming thresholds.

That bureaucratic sleight of hand builds roughly a decade of delay into the system. Sclerotic by design.

Missing from the article: Jared Isaacman offered to fix Hubble for free, and NASA turned him down.

Best one-lesson favor I ever got was dimensional analysis in high school.

Do it, and most basic physics is trivial.

Hop David is the person on the internet who the author wants to talk to about whether their math on orbital tethers is correct.

Engineering an improved rubisco into the food supply (or the notional biological carbon capture stream) would significantly boost to the carrying capacity of our planet.

FWIW, the SO2 injection rate for climate engineering is about 1/10 of our current tropospheric injection rate from burning fossil fuels.

I bring it up to illustrate that we are already making consequential choices about the climate.

There is no chance that we will remain below 1.5C. Because there is (rightly) moral value attached to staying below 1.5, that fact is (also) hard to accept.

The formalized narrative makes sense through a values-based lens, as does the conversation moving through stages of grief as geophysics makes itself felt.

No, just put them inside a radiation shield and pump heat out. Same protocol for the humans.

ChatGPT is the perfect VC. Superhuman pattern matcher, and unable to recognize any signal w/ non-zero Shannon entropy.

Exact replacement. POSIWID.
