%description
'PaleoClim' <http://www.paleoclim.org> (Brown et al. 2019,
<doi:10.1038/sdata.2018.254>) is a set of free, high resolution
paleoclimate surfaces covering the whole globe. It includes data on
surface temperature, precipitation and the standard bioclimatic variables
commonly used in ecological modelling, derived from the 'HadCM3' general
circulation model and downscaled to a spatial resolution of up to 2.5
minutes. Simulations are available for key time periods from the Late
Holocene to mid-Pliocene. Data on current and Last Glacial Maximum climate
is derived from 'CHELSA' (Karger et al. 2017,
<doi:10.1038/sdata.2017.122>) and reprocessed by 'PaleoClim' to match
their format; it is available at up to 30 seconds resolution. This package
provides a simple interface for downloading 'PaleoClim' data in R, with
support for caching and filtering retrieved data by period, resolution,
and geographic extent.
