If plants were a bit more ambulatory, Peter Adler and Michael Stemkovski might find their work to be a bit less urgent. If whenever the weather got too hot or dry, crested wheatgrass, yellow rabbitbrush and silvery groves of quaking aspen could choose to wriggle their extremities out of the soil and wander upslope to more hospitable environments, plants like these might have a better chance at surviving climate change. But, of course, they can't.
