If the climate-change induced sea level rise needs 1-2 metres of mitigation, and you have 100-200 metre deep depressions, you need to cover 1% of the Earth's surface (total, not just land) with these seafloods. Doesn't seem like a plausible mitigation, I'm puzzled why the article proposed it.
The other benefits might be interesting locally some places.
- jacobr1 3y agoA few considerations: 1) you don't need to fully mitigate the sea-level rise for this to be of value. Even a few cm might make a difference on the margin for certain areas. 2) The projects themselves might be a value if we really could increase the productive value of currently arid parts of the land with net-positive environmental impact, so the sea-level rise doesn't matter or let's us do the project without worrying about sea-level drop. If we really had too-cheap-to-meter power for desalinization, then these projects might start to make sense, but it seems too soon to me.
