#WNITU Waking Beasts: Underwater Volcanoes Roused by Ice Ages

#WNITU

Do fire and ice link up to alter Earth’s climate?

The climate-driven rise and fall of sea level during the past million years matches up with valleys and ridges on the seafloor, suggesting ice ages influence underwater volcanic eruptions, two new studies reveal. And because volcanic chains suture some 37,000 miles (59,500 kilometers) of ocean floor, the eruptions could pump out enough carbon dioxide gas to shift planetary temperatures, the study authors suggest.
