CO2 drop and global cooling caused Antarctic glacier to form

(PhysOrg.com) -- Global climate rapidly shifted from a relatively ice-free world to one with massive ice sheets on Antarctica about 34 million years ago. What happened? What changed? A team of scientists led by Yale geologists offers a new perspective on the nature of changing climatic conditions across this greenhouse-to-icehouse transition—one that refutes earlier theories and has important implications for predicting future climate changes.
