Using the simple anomaly method (modifying a historical baseline with differences or ratios projected by General Circulation Models), scientists from the California Academy of Sciences downscaled monthly average temperature and monthly total precipitation from 16 different global circulation models (GCMs). The GCMs were described in the latest Intergovernmental Panel for Climate Change (IPCC 2007) and archived at the WCRP PCMDI (http://www-pcmdi.llnl.gov/ipcc/about_ipcc.php). Monthly maximum temperature and monthly minimum temperatures were downscaled from the only 6 GCMs that archived these particular variables. Scientists used Worldclim v.1.4 (Hijmans et al 2005) at 5 arc-minute (~10km) spatial grain as the current...
This dataset represents the predicted distribution for Redwood (Sequoia sempervirens) for the years 2090s (ten year period average), based on the agreement of 2 or more out of 5 niche modeling techniques (Climate Space Model, Envelope Score, Environmental Distance, GARP, and SVM) and monthly precipitation and average temperature from 12 GCMs from the A2 emission scenario. Localities used to produce the model were resampled from the known current distribution, data provided by Save the Redwood League (http://www.savetheredwoods.org/).
