National Climate Change Viewer (NCCV) Unveiled

Something news from the US DOI in this climate viewing tool – The new tool gives citizens and resource managers the opportunity to look at climate-driven impacts on watersheds and map projected changes at the local, regional, state and watershed levels.

The USGS National Climate Change Viewer (NCCV) includes the historical and future climate projections from 30 of the downscaled models for two of the RCP emission scenarios, RCP4.5 and RCP8.5. RCP4.5 is one of the possible emissions scenarios in which atmospheric GHG concentrations are stabilized so as not to exceed a radiative equivalent of 4.5 Wm-2 after 2100, about 650 ppm CO2 equivalent. RCP8.5 is the most aggressive emissions scenario in which GHGs continue to rise unchecked through the end of the century leading to an equivalent radiative forcing of 8.5 Wm-2, about 1370 ppm CO2 equivalent. The application also provides access to comprehensive, summary reports in PDF format and CSV files of the temperature and precipitation data for each geographic area.
