Ocean's Circulation And Its Effects On Our Climate

redOrbit: Scientists have long believed that global warming and levels of CO2 were associated. As levels of carbon dioxide increased, so too did the Earth's temperatures. Now, paleoclimate researchers have studied ancient skeletons from microscopic plankton from the Miocene period to better understand our climate 12 to 5 million years ago. They found warmer periods and increased levels of CO2 didn't always operate hand in hand, saying the two effects once operated independently of one another. These researchers...
