It's the OIG, the government's auditors. They're not equipped to make engineering decisions, but they are experts at seeing whether that policies ostensibly written by engineers are being followed.

I'm not up to date on the latest literature re: the Otis miss. Is the conventional thought that the ocean was in fact warmer than the models supposed, either at the surface or with a warmer upper-mixed layer? If the problem was lack o

Although it's obviously difficult to crack open an ML model, they do perform enough computation to have potentially learned something like the dynamical equations for the atmosphere. At the same time, some ML models are surprisingly pa

Hybrid models have the conceptual edge, but it's not yet obvious that they'll become the dominant AI forecasting paradigm. The hybridization acts as a strong regularizer. This is a good thing, but it's not yet obvious that i

Unfortunately, it seems like global warming causes damages that increase rather than decrease on the margin. That is, the aggregate economic damage of going from 1°C warming to 1.5°C warming is smaller than the damage of going from 1.5° to

That's where leverage comes in. Under more ordinary conditions, the 22 year-old would have something like 80% in equities and 50% in bonds, using leverage to have a net 130% invested. Under current conditions, that allocation is more

Applying optimal portfolio theory to the long history of market returns suggests that the most risk-efficient allocation is something like 60% stocks and 40% bonds. The diversification reduces volatility faster than it reduces the overall
