Featured: Plant responses to increasing CO2 reduce estimates of climate impacts on drought severity

Proceedings of the National Academy of Sciences | Swann et al. [2016]

We show that the water savings that plants experience under high CO2 conditions compensate for much of the effect of warmer temperatures, keeping the amount of water on land, on average, higher than we would predict with common drought metrics, and with a different spatial pattern. The implications of plants needing less water under high CO2 reaches beyond drought prediction to the assessment of climate change impacts on agriculture, water resources, wildfire risk, and vegetation dynamics.
