The hydrologic cycle: A major variable during earth history

摘要: Abstract Water plays a central role in nearly all Earth processes and the evolution of planet. However, despite significance water, our knowledge it as part global system meager. In fact, for paleoclimatology primary focus on planetary is centered temperature variations little attention directed towards hydrologic cycle. Model analyses presented here based series simulations utilizing Community Climate (CCM) at National Center Atmospheric Research demonstrate that cycle highly sensitive to climate change climatic forcing factors such changes atmospheric carbon dioxide, plate tectonics, paleogeography, orbital variations. The implications large sensitivity are considerable importance. water explaining much Earth's record has probably been underestimated. importance history may also suggest should be interest studies future change.
