Analogues from Earth’s Past Bode Ill for Coral Reefs, Marine Ecosystems

In a bid to anticipate the effects of a warming world, climate scientists around the world are scouring the geological record for modern-day analogues – periods of Earth history when the concentration of carbon dioxide (CO2) in the atmosphere reached or exceeded the 400 parts per million (ppm) we find today. Delving into climate, marine biology, ecosystems and the marine ecology of 42 million …

Study of Pliocene Arctic Yields Insights into Climate Change Today, and for the Future

Study of the Arctic Pliocene will reveal clues to climate change today and into the future

The mean monthly average concentration of carbon dioxide in the atmosphere as measured at NOAA’s Earth System Research Laboratory at Mauna Loa, Hawaii exceeded 400 parts per million (ppm) for the first time in modern history back in May. The last time atmospheric CO2 reached this level was during the Pliocene Epoch some 3 million to 5 million years ago, earth scientists believe. Thing …
