Major themes | Theme 2

Theme 2: How are climate and atmospheric composition regulated on time scales up to a million years?

The projects in this theme have compiled data from multiple sources to give a global picture of changes over different timescales of various aspects of the Earth system, such as the coverage of vegetation and ice, the marine biota, atmospheric concentrations of carbon dioxide, methane and dust, and precipitation. Comparing these reconstructions with climate model simulations has helped to validate the climate models.
