Measurable, instant, continuous carbon capture and safe, reliable, permanent storage. Sound too good to be true?

Actually, this is exactly what engineered solutions like DAC (Direct Air Capture) and geological sequestration claim to bring to our carbon removal toolkit. The former promises technological innovation that does a tree's job better than a tree. The latter offers one of our surest bets that once we've got the CO2 down, we can keep it down, out of the atmosphere for as good as forever.

Naturally, however, these unnatural solutions have catches, complications... even controversies. Are we engineering our ways out of one problem and into several others?
