4 Gt is roughly all the anthropogenic CH4, responsible for about a third (or possibly a half) of temperature rise. After that we will continue at a lower level in order to keep curating the level and as a precaution against methane bursts.

4 Gt of CH4 is considered roughly equivalent to 120 Gt of CO2

Fascinating - saving the planet by adding iron chloride to the mix of pollutants emitted by diesel-powered tanker ships in order to convert methane into CO2. I can't imagine many more ways in which the approach could be unintuitive, but if it works and the side effects are thoroughly understood, I appreciate the pragmatism!

Ah, the ISA approach. I could never calibrate the fringy-ness of that idea.

Do you have evidence that it works in-situ, or any ideas of how to test this in an observable way? If so, there are folks interested.

It is demonstrated in the lab and we are developing a way to assay what’s going on in the open air. Lot of interesting work in this area.

Do you have papers/whitepapers you can share (privately or otherwise)?

(I run a climate engineering group to help accelerate mitigation/removal methods.)

Click on the menu item at the top of the page marked “Science”. All the rest is for the lay audience.

Can you say more about your group?
