Climate Change Destroying Walden Pond’s Flowers | Wired Science from Wired.com
Comparing data meticulously gathered by Henry David Thoreau more than a century and a half ago with more recent observations, Harvard biologists report in the Proceedings of the National Academy of Sciences that more than a quarter of Walden’s plant species have already been lost. And an additional 36 percent are in imminent danger, including lilacs, roses and buttercups.

“It had been thought that climate change would result in uniform shifts across plant species, but our work shows that plant species do not respond to climate change uniformly or randomly,” said co-author Charles Davis, a biologist at Harvard, in a release.
