Alkenone-based tropical \r\nSST records from the major ocean basins show coherent glacial-\r\ninterglacial temperature changes of 1° to 3°C that align with \r\n(but slightly lead) global changes in ice volume and deep ocean\r\ntemperature over the past 3.5 million years. Tropical temperatures \r\nbecame tightly coupled with benthic d18O and orbital forcing \r\nafter 2.7 million years. We interpret the similarity of tropical \r\nSST changes, in dynamically dissimilar regions, to reflect \"top-down\" \r\nforcing through the atmosphere.  The inception of a strong carbon \r\ndioxide-greenhouse gas feedback and amplification of orbital forcing \r\nat ~2.7 million years ago connected the fate of Northern Hemisphere \r\nice sheets with global ocean temperatures since that time.","author":{"name":"Herbert, T.D., L.C.
