Climate Visualization Maps

These climate visualization maps for the years 2025 and 2095 were created from data provided by the National Center for Atmospheric Research (NCAR) and available through EOS-WEBSTER's Climate Changes in the 21st Century Data Collection (see below). These maps show projected temperature and precipitation changes from the 1961 to 1990 average. These data are included in the 2007 IPCC Assessment, AR4.

For more information on the Climate Changes in the 21st Century Data Collection, please see our Data Guide. You can order these data from the Order Data Page.

Commit Scenario: Temperature Changes: This scenario is based on conditions that already exist (e.g., climate change we are already "commited" to) and assumes that greenhouse gas emissions were stabilized at year 2000 levels. (CO2 = 393.7 ppmv, CH4 = 1738 ppbv, N2O = 315.5 ppbv). Details

SRES A1B Scenario: Temperature Changes: Atmospheric CO2 concentrations reach 720 ppm in the year 2100 in a world characterized by low population growth, very high GDP growth, very high energy use, low land-use changes, medium resource availability and rapid introduction of new and efficient technologies.
