Earth Science Meeting in DC #4
Jake Weltzin from the USGS is talking about using phenology to study climate change effects. Phenology is the study of the variations that occur seasonally in plants and animals. When leaves turn color in that fall, that's a phenological event. The timing of these events offers scientists great clues for climate change. In a recent study 62% of species are showing predictable changes in response to climate warming. This means their springtime changes are occurring earlier. For some species, such as migratory species, this can be a deadly trend. The USGS Phenology effort is looking for student scientists and others to help perform a hundred thousand observations. This is a great opportunity for science students to get involved.
