Hm, I'd go back to Germany and WWII, and the ~2,600* scientist leaving within a year.
And yeah, I'd think Europe (as a whole) draws at least as many as Canada in this case.
* That's a key part here: these numbers are all rather low, and still, Germany/European science has yet to recover.

That race will continue for the rest of most of our lifetimes.
And yeah, that heat pump CoP hovering around 3 or 4 without even trying is a key part of the story.
The fact that some now achieve CoPs > 7 is…wow.

Holy shit. This company claims it has developed an air-source heat pump with a COP of *7* (3-5 is considered good). For you non-nerds, that basically means it produces 7 units of heat for every unit of electricity it consumes. How are they doing it? You're not gonna like this answer, but: it's AI.

The purpose is to raise the marginal private cost to be closer to the marginal social cost of each tonne of CO₂ emitted. Econ 101.

Maybe the proceeds could be used for direct air capture or something... the fact is ppl need to fly

None of this is banning flights for anyone.
But let's not pretend it's OK to do so while using the atmosphere as a free sewer.
