Cal-Adapt 2.0

Cal-Adapt is a climate change geospatial data tool for California, that is developed and maintained by the University of California, Berkeley Geospatial Innovation Facility with funding and oversight by the California Energy Commission. Cal-Adapt offers localized climate change projections for the state produced by California's scientific and research community. The updated version, Cal-Adapt 2.0, has been released with new, high-resolution climate projections, enhanced visualizations, and improved access to data. Development of Cal-Adapt was a key recommendation of the 2009 California Climate Adaptation Strategy

This interactive climate change data visualization tool allows the user to explore projected changes in temperature, extreme heat, precipitation, snowpack, wildfire, and sea level rise in California. A series of interactive maps provide detailed statistics for what climate models project for a specific location. The user can select among four different climate models and two emissions scenarios. There is also the option to download high resolution downscaled daily, annual and monthly climate projections for a local area in NetCDF or GeoTiff formats.

Cal-Adapt 2.0 includes new, high-resolution climate projections using downscaling methods developed by researchers at the Scripps Institution of Oceanography at the University of California, San Diego. The new projections align with the models and emissions scenarios that are used for the United Nations’ Intergovernmental Panel on Climate Change (IPCC) latest assessment report, the Fifth Assessment Report (AR5).

In addition, Cal-Adapt 2.0 includes visualization enhancements such as the ability to investigate disadvantaged communities using CalEnviroScreen, visualization of historical observed data through 2005, and more.
