Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Nanne just wrote everything I would've written.

Geoengineering is a last resort, and can only be used transitionally, in the case of catastrophic, runaway climate change (warming at and above the 5 degrees celcius range). Like lobbing a nuke at an incoming meteorite. It can't replace reducing CO2 emissions.

We also need to prioritise. Planting trees and mechanical air capture of carbon are better than injecting SO2 into the stratosphere, which again is better than seeding the oceans with iron dust. In my opinion...

The problem we will see lies partly with the political discourse on climate change. It is now all about combatting CO2, whereas it needs to be about shifting to a sustainable economy.

That's my thoughts to a T.

This fits Crutzen's position, which seems well considered.

It also fits into situation (1) in this comment, and avoids the trap of situation (2).
