When you take pretty much the same walk every day, camera in hand, you may have trouble finding new things to photograph. You may look in vain for something different, puzzling, or mysterious.

But there is something to be said for combing the same territory over and over, as scientists are finding from studying the detailed record keeping of Henry David Thoreau.

“ ‘As far as I know, there is more information about the effect of climate change in Concord than any other place in the United States,’ said Richard Primack, a Boston University biologist who calls Concord a living lab for his research. …

Primack, writes Kathleen Burge at the Boston Globe, “has researched how climate change has affected the flowering times of plants, comparing modern data with the information Thoreau collected between 1852 and 1860. Primack and his lab found that for every 1 degree Celsius increase in mean spring temperature, plants bloom about three days earlier. …

“Primack came to his work about a decade ago, when he decided to change the direction of his research. He had been studying the effects of climate change on plants and animals in southeast Asia and decided, instead, to focus on his home state.

“But when he began searching for older records of plant flowering times in the United States, he came up short. Finally, after six months, someone told him about Thoreau’s journals.

“This was kind of a gold mine of data,” Primack said. “As soon as we saw it, we knew it was amazing.” More from the Globe.

Keep an eye open for the upcoming Thoreau exhibit at the Concord Museum April 12 to September 15, described here.
