A few of my working notes on direct air carbon capture (DAC), and the implications for climate change: http://cognitivemedium.com/dac-notes

I love how you use this as a way of bounding pessimism without anchoring too much on the specifics — it’s hard to get people thinking along those lines! FWIW, (thermodynamic entropy of mixing bound) x (reasonable price of energy) does seem to be below $10/tonne for DAC itself:pic.twitter.com/AcWermV81H

Yeah, people mix up "Is it _possible_ to solve?" with "And what's the best possible / most realistic approach?" They can't answer (b), which is a much more complex question, so get pessimistic about (a). Hard to get ppl out of this mindset.

In addition to Adam's notes, let me also mention the NAS survey report, freely available here: https://www.nap.edu/catalog/25259/negative-emissions-technologies-and-reliable-sequestration-a-research-agenda … It's a pretty helpful survey, IMO!
