DESCRIPTION

The Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report
(AR4) Observed Climate Change Impacts Database contains observed responses to
climate change across a wide range of systems as well as regions. These data
were taken from the Intergovernmental Panel on Climate Change Fourth Assessment
Report and Rosenzweig et al. (2008). It consists of responses in the the
physical, terrestrial biological systems and marine-ecosystems. The observations
that were selected include data that demonstrate a statistically significant
trend in change in either direction in systems related to temperature or other
climate change variable, and the is for at least 20 years between 1970 and 2004,
although study periods may extend earlier or later. For each observation, the
data series is described in terms of system, region, longitude and latitude,
dates and duration, statistical significance, type of impact, and whether or not
land use was identified as a driving factor. System changes are taken from ~80
studies (of which ~75 are new since the IPCC Third Assessment Report) containing
more than 29,500 data series. Observations in the database are characterized as
a "change consistent with warming" or a "change not consistent with warming",
based on information from the underlying studies.
