The collective will we'd need to deploy this globally would probably indicate that we also somehow magically gained the collective will to reduce emissions.
This is the problem with some of the geo-engineering approaches. We've shown that we can't really change how society and industry operate enough to reduce emissions, so what makes us think we can do the same for carbon capture? How do you actually get every farm to do this?
- delecti 3y agoThe comment you replied to suggested carbon credits. That seems like a pretty obviously good answer. We're bad at forcing people to make broad changes, but nudging with money like that is often effective.

Last year my local utility generated more power from wind than there was demand. People do care and are making change. Change is slow to come, and even after it happens takes a long time to make a difference, but there are signs of change and the cause is being taken care of. Don't take that too far: there is a lot of work to do. However we have a good idea what that work is we just need to apply it.

From your source (thank you for the read): > Claus concludes, “Based on the Montreal Protocol and the decrease of anthropogenic ozone-depleting substances, scientists currently predict that the global ozone layer will reach its normal state again by around 2050.”

- ilyt 3y agoOzone hole was "just" replacing one chemical with another and changing refrigerator units a bit; CO2 emissions are orders of magnitude bigger as near-everything related to industry or standards of living emits CO2 in direct or indirect way.
- bluGill 3y agoMy utility generated electric power via wind last year than all customers combined used. Electric cars are obviously taking over. Those are very encouraging signs since a large portion of CO2 comes from electric or transport uses. There are other uses aw well to work on, and some challenges in those areas, but things are looking very good.
- PeterisP 3y agoThe hope (and IMHO only reason) for geo-engineering approaches is that they can enable achieving a large effect with a much smaller political sacrifice than cutting people's consumption or preventing some countries from increasing their consumption to "first-world" levels, and at a smaller cost than that. If someone finds a plausible way to reduce a major part of global greenhouse gases that costs merely, say, 10 or 100 billion, then that's something that a few major countries can do (and fund) unilaterally and doesn't need global consensus, unlike major emissions reductions which have the tragedy of commons problem where if you do that and other major emitters don't, then you've crippled your economy but haven't prevented any of the bad consequences.
