The study is considering extremes, but that's not realistic.
Completely switching to renewables will be more expensive than planting some trees for instance. If we want the most cost effective methods, it will be a mix of both, maybe more on the "burning less fossil fuels" side than on carbon capture, but neither extreme make sense.
And it may turn out that a complete switch to renewables may not be enough anyways. We may need carbon capture too, and maybe some geoengineering.
- loeg 2y agoThe dollars don't actually substitute, either. We can spend on both more than we'd be willing to spend only on renewable sources.
