New study shows vegetation controls the future of the water cycle

Mon, 02 Apr 18 00:10:40 -0700

Columbia Engineering researchers have found that vegetation plays a dominant role in Earth's water cycle, that plants will regulate and dominate the increasing stress placed on continental water resources in the future. 'This could be a real game-changer for understanding changes in continental water stress going into the future,' says Professor Pierre Gentine. In this paper, he demonstrates vegetation's key role in responding to rising CO2 levels and shows how plants will regulate future dryness.

Untangling the role of climate on sediment and reef evolution over millennial timescales

Tue, 27 Mar 18 00:02:40 -0700
