Abstract:
|
Climate changes are top biodiversity shapers, both during the past and future. Mapping the most
climatic stable and unstable zones on Earth could improve our understanding of biodiversity
distribution and evolution. Here, we present a set of maps based on a global scale, high resolution (ca.
5 km) new Climate Stability Index (CSI). The CSI considers bioclimatic variables for two different time
ranges: (1) from Pliocene (3.3 Ma) to the present (CSI-past map set), using 12 time periods of PaleoClim
representing warm and cold cycles; and (2) from present to the year 2100 (CSI-future), using nine
general circulation models of climate change of four periods available from WorldClim. We calculated
standard deviation of the variables and selected an uncorrelated set for summing, normalizing
and obtaining the CSI maps. Our approach is useful for fields such as biogeography, earth sciences,
agriculture, or sociology. However, CSI is an index that can be re-calculated according to particular
criteria and objectives (e.g. temperature variables); maps are, therefore, customizable to every user. |
