Link to Data in Data Basin. These data sets from the California Academy of Sciences show climate projections (temperature and precipitation) for all four seasons. From the California Academy of Sciences' metadata (for a precipitation projection): 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 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 total precipitation...

The loss or decline of culturally significant plants is a major concern for many tribal managers. Culturally significant plants are essential to many aspects of life for tribal members, including medicine, ceremonial practices, and traditional food dishes. In many parts of the U.S., droughts, floods, and changes in the timing of frost events are stressing these plants and in some cases have led to decreases in their areas of suitable habitat or a reduction in their resistance to disease. The goal of this project is to hold a research symposium that will bring together tribal resource managers and scientists from a range of disciplines in the South Central region to identify which culturally significant species...
Distribution maps of ensemble averages and standard deviations for each species modeled future bioclimatic envelope. These maps demonstrate the diversity of projections from the array of modeled studied by the project. Consists of 200 layers: 100 species (50 bird, 50 plant) 2 stats (avg, std) value is 0..1 suitability.
The CA Academy of Science and Point Blue Conservation Science conducted a systematic analysis of uncertainty in modeling the future distributions of ~50 California endemic plant species and ~50 California land birds, explicitly partitioning among 5 alternative sources of variation and testing for their respective contributions to overall variation among modeled outcomes. They mapped the uncertainty from identified sources, which can guide decisions about monitoring, restoration, acquisition, infrastructure, etc., in relation to climate change.

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/).

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
