Geochemical method finds links between terrestrial climate and atmospheric carbon dioxide
Storrs CT (SPX) Apr 23, 2013
Nearly thirty-four million years ago, the Earth underwent a transformation from a warm and high-carbon dioxide "greenhouse" state to a lower-CO2, variable climate of the modern "icehouse" world. Massive ice sheets grew across the Antarctic continent, major animal groups shifted, and ocean temperatures decreased by up to 5 degrees. But studies of how this drastic change affected temperatures on land have had mixed results. Some show no appreciable terrestrial climate change; others find cooling of ... read more
