In Global Change Biology, Cat Chamberlain, Elizabeth Wolkovich, and colleagues reviewed studies and metrics for measuring false spring and freeze damage risk, and suggest an integrated approach for modeling future outcomes. Abstract»
Most wine is produced from the same 12 varieties of grapes. Agricultural crops, including wine grapes, are predicted to be greatly impacted by climate change. Published in Nature Climate Change, Elizabeth Wolkovich,Ignacio Morales-Castilla and co-workers discuss how the other ~1100 varieties of grapes available, and the diversity of their attributes, may play an important role in the future.

The Tree Spotters monitor the life cycles of trees, noting when they bud, grow leaves and turn colors. The data they collect is used by scientists to study everything from seasonal allergies to how climate change may be affecting New England’s trees. Read more from WGBH.
And Again: Photographs from the Harvard Forest John Hirsch chronicles the research, scientists, and ephemera of the Harvard Forest–a 3,750-acre research forest in Petersham, Massachusetts. Essays by David Foster, Clarisse Hart, and Margot Anne Kelley expand the scope of this photographic exploration at the nexus of science and art. Hirsch is attentive to both the […]
Each year we witness the seasonal schedules of plants—when they flower, fruit, and unfurl and drop their leaves—in our gardens, parks, and wild areas. The details of these schedules are vitally important to pollinators, herbivores, and frugivores, and to horticulturists, farmers, landscape architects, and ecologists. Even so, we know surprisingly little about the phenology (or […]
The USA National Phenology Network’s most recent Annual Report includes a full page feature on the Arnold Arboretum Tree Spotters—a volunteer citizen science program dedicated to collecting phenological data to aid scientists studying climate change. Check out the feature on page 6.
Published in Nature Climate Change (abstract»), Elizabeth Wolkovich and Ben Cook examined the phenology of wine grapes and its relationship to climate change. Using 500 years of harvest dates across France, they found that warming due to climate change is linked to much earlier harvest dates. Harvard Gazette»NPR»
Recording details about when plants flower or leaf out (phenology) may not seem like a momentous undertaking at first glance, but when aggregated, this data can reveal much to scientists about how plants are faring in our changing climate. In order to better observe, appreciate, and understand trees and their life cycles, it helps to […]
Speaking at a State Department forum on Tuesday, Harvard President Drew Faust said that universities can and must play a key role in developing solutions to climate change, citing the research, teaching, and convening strengths of research institutions. Read the Harvard Gazette article here.
