It's insane.

The thermodynamic minimum amount of energy needed to extract CO2 at 450 ppm is 120 kWh per tonne. Current experimental carbon capture plants run at about 5 % efficiency. If we assume we can double their efficiency and can magically produce as many plants as we need, to remove 20 Gt of CO2 per year (half our emissions) we would need 24,000 TWh of energy per year.

That is the entirety of the world's electricity production. To remove half our emissions.

Carbon capture is a non-runner.

My entire life has vim key bindings. My window manager and browser all have vim key bindings. I work in vim. I write my shopping lists in vim.

I really can't overstate how ingrained vim is in my day to day life. Bram had a big impact.

It's called Title Case. There are different rules depending on which style manual you're using. Some people just capitalise everything. Some people don't use it at all.
