Sentences with phrase «year time scale»

By the way, we also did a paper on millennial - scale solar geoengineering (Cao et al, 2016) showing that, in at least one climate model, solar geoengineering behaves quite well on the 1000 - year time scale with no substantial long term growth in climate change as ocean circulation and such adjusts to the new conditions.
