The late Pliocene onset of major Northern Hemisphere glaciation is one of the most important steps in the Cenozoic global cooling. Although most attempts have been focused on high-latitude climate ...
... and internal factors such as ocean currents. "If man had never started burning fossil fuels, the sun might have been the only agent regulating the climate until the next glaciation," he said.
... for the past several million years, Earth's climate has been characterized by large-scale glaciation, although we currently live in an interglacial of this geologically rare state. Earth's last major ...
