Fewer workers. Fewer international students. More people leaving.

A "step in the right direction" according to the PM.

Impossible to take PM/govt seriously on growth if they are deliberately reducing it (and making the fiscal position worse) *as a matter of policy*.

The biggest misunderstanding of Carbon Dioxide Removal (CDR), IMHO, is that many assume it is a replacement for emissions reductions. As in, more CDR, less emission reductions. No. Emissions need to go down as fast as possible, even faster, no matter how much (~feasible) CDR you have.

You can even put an exact date on the day when Brussels finally gave up on its decade-long dream of seeking to be the predominant global tech regulator that would rein in American tech titans like Google and Apple.

It came last Wednesday — Nov. 19.

Turns out that sucking CO2 from air is fairly expensive and not easy (and we won't be able to do it at the scale that is needed to ease CO2 emissions in any great quantity at timescales needed). Curbing CO2 emissions is the easiest and fastest way, if we can just agree on it as a society...

LLMs are fast becoming a major source of information.

In a new piece over at The Climate Brink, I argue that LLMs are fundamentally consensus machines, and could help defragment our information ecosystem – at least if their creators do not put thumbs on the digital scale.
