An early sign of spring, earlier than ever
Date:1/16/2013

Record warm temperatures in 2010 and 2012 resulted in the earliest spring flowering in the eastern United States in more than 150 years, researchers at Harvard University, Boston University and the University of Wisconsin have found.

"We're seeing plants that are now flowering on average over three weeks earlier than when they were first observed and some species are flowering as much as six weeks earlier," said Charles Davis, a Harvard Professor of Organismic and Evolutionary Biology and the study's senior author. "Spring is arriving much earlier today than it has in the past."

To explain spring's early arrival, Davis and his co-authors, Boston University biology Professor Richard Primack, BU postdoctoral researcher Elizabeth Ellwood and Professor Stanley Temple at the University of Wisconsin, point to temperature increases resulting from global climate change. Using data collected in Massachusetts and Wisconsin from the mid-1800s to the present day, they show that the two warmest years on record 2010 and 2012 also featured record breaking early spring flowering.

Significantly, researchers found that the early arrival of spring was predicted by historical records, and that plants haven't shown any sign of reaching a threshold for adjusting to warming temperatures.

"It appears that many spring plants keep pushing things earlier and earlier", Davis said.

To conduct the study, Davis and colleagues relied on two "incredibly unique" data sets.

"The data were initiated by Henry David Thoreau in the mid-1800s," Davis said. "He was making observations on flowering times across Concord, Massachusetts for nearly a decade. In central Wisconsin, the data were collected by environmental pioneer Aldo Leopold beginning in the mid-1930s.

"The striking finding is that we see the same pattern in Wisconsin as we see in Massachusetts," Davis said. "It's amazing that these areas are so far apart and yet we're
