You can take 1) a baseline climate run (eg 1xCO2, or 1% increase a year, whatever) 2) then add some extra CO2 on top (say constant 2xCO2) and let your AI stick a geoengineering layer on top of that, to try and dial it back down to the baseline The detection AI doesn't know which is the baseline -

The first two don’t require ANN. I don’t get what your detection network is supposed to do. We have simulations of the baseline climate and we know what it is. If we generate simulations of a climate that is usefully different, that’ll be pretty clear. If the differences are subtle, then it

I can think of a couple of counterpoints 1) a cheap climate model may allow a neural network to learn some basic strategies pretty quickly - like mixing CCT with SAI to control precip 2) training AI on weird climates (8x CO2, anoxic oceans) might prepare us for weird stuff we'd otherwise miss 3)

Thanks! I was actually thinking of reinforcement learning in my previous response… agree that GAN is not at all applicable here. I think a stronger statement is in order… this is NOT a problem where any ANN-based algorithm is likely to be of much value in the next 10+ years, and maybe never.

Hi everyone, I asked a data scientist who works on deep learning -- Alex Orona (https://www.linkedin.com/in/alexorona/) -- about this. Here is his email: "Can't comment on the climatological aspects of the question (it's well outside my domain), but here is my feedback on the machine

Andrew I did something similar to optimize the control of a wave energy generator in a 1/100 scale test tank.  We want to control forces on the model in three degrees of freedom, pitch heave and surge during the passage of a 51.2 second repeatable 'random' sea with 16 adjustments per second.
