“Improved drainage results in a drier landscape over a decadal timescale, and the process then becomes self-limiting,” said Scott Painter, who leads the Watershed Systems Modeling group at ORNL.

9300-year old vegetation remnants found under receding glaciers in Northern Sweden show that the trees once grew where tundra exists today, meaning it was warmer.
