Observed changes in phenology across the USA: A regional review for the 2013 National Climate Assessment, Hawaii and Pacific Islands Regional Information Sheet

This is one in a series of eight, geographic region-focused information sheets that summarizes documented changes in plant and animal phenology over the past century across the United States. This summary is based on long-term studies (10 years or more) published in the primary scientific literature since 2001. A forthcoming manuscript synthesizes the findings of the eight regional information sheets.

This information was developed in support of the U.S. Global Change Research Program’s National Climate Assessment and can be used to facilitate preparation for the cascading effects of ongoing climate change.
