P rojections of our future under climate change paint a picture of extreme weather and acidified oceans, a world many of ...

In the modern global climate, higher levels of carbon dioxide in the atmosphere are associated with rising ocean temperatures. But the seas were not always so sensitive to this CO2 "forcing ...

Recent reconstructions of carbon dioxide levels for the late Miocene time period (roughly 5 to 13 million years ago) suggest that CO2 concentrations for the period were only 200-350 parts per million.

The oceanographers examined cores -- sediment samples from deep parts of the ocean floor -- from the Oligocene-Miocene era, roughly 23 million years ago, from areas near Tasmania and Antarctica in ...

In a recent study published in Nature, Hess and her co-authors looked to the Miocene warm period about 16 to 14 million years ago when temperatures and atmospheric carbon dioxide concentrations ...

While most open ocean sharks disappeared after the event, coastal sharks survived, and today's sharks most likely ascended from the survivors. Terry Goss via Wikicommons under CC BY-SA 3.0 ...

Alternatively, the cause may lie in the Southern Ocean, thousands of kilometers away. During past prolonged warm periods, the exchange water between Southern Ocean surface waters and the deep ocean ...

During the Miocene epoch, as many as 100 species of apes roamed throughout the Old World. New fossils suggest that the ones that gave rise to living great apes and humans evolved not in Africa but ...
