Thoreau & Global Warming “Henry David Thoreau’s neighbors in Concord, Mass., thought his passion for flowers and constant scribbling in journals was a little strange. But scientists are now using those meticulous botanical writings as a benchmark to measure the effects of global warming” (The Wall Street Journal, Sept. 27, 2007) Read two articles about how a Boston University biologist has used Thoreau’s seasonal charts and nature writings, as well as those of other Concord naturalists, to prove that some common plants in the region are flowering at least three weeks earlier than in Thoreau’s time – with consequences for wildlife.
