Trees Use Water More Efficiently as Atmospheric Carbon Dioxide Rises

July 10, 2013 — Spurred by increasing levels of atmospheric carbon dioxide, forests over the last two decades have become dramatically more efficient in how they use water, a Harvard study has found.

Studies have long predicted that plants would begin to use water more efficiently as atmospheric carbon dioxide levels rose.
