Ocean closures and global cooling events

A modeling study finds that the upheaval and weathering of a group of rocks called ophiolites in the wet tropics during the closure of the Neo-Tethys Ocean, which separated Gondwana and Eurasia, may have driven decreases in atmospheric carbon dioxide and subsequent global cooling after the Cretaceous Thermal Maximum and the Early Eocene Climatic Optimum, findings that suggest that the closures of east-west, low-latitude oceans may help explain other global climate cooling episodes. - Read at PNAS.org
