We release it because it allows us to produce energy (burn something). To remove it from atmosphere would require to put it some higher energy state so that we can store it and that require again some source of energy. Pumping pure CO2 in some mine will probably not do the job.
In reality, we will try to just reduce temperature without removing CO2, but CO2 causes problems other than tempterature rise. See ocean acidification.
There seems to not be any good solution really.
- ep103 10y agoyeah, but we release it because burning things is an easy way of releasing energy whenever / wherever we need it. Reducing CO2 can be done pretty much anywhere in the world. So if we needed to build a nuclear powerplant somewhere just to power our CO2 scrubbers, so that our cars and planes could burn fuel, that's completely doable.
- collyw 10y agoPlant a hell of a lot of trees?
- lisper 10y agoThat is actually the most effective way of scrubbing CO2. The problem is that trees take up a lot of valuable real estate.
- the8472 10y agoLots of unused land are shrubs, grass and hillsides. The mediterranean coast used to be all trees a little more than two millenia ago[0]. Some semi-arid zones around deserts could also support reforestation.

- madshiva 10y agoJust stop growing is the solution itself.
- TeMPOraL 10y agoIf we were to "just stop growing", it would pretty much collapse the entire civilization on the spot. Unfortunately, the assumption of growth is the basis of not just the economy, but a lot of things in the society. Sure, I think we should move away from the growth-based economy. But this needs to be a gradual process.
