Until now, scientists presumed that seafloor volcanoes exuded lava at a slow and steady pace, but Tolstoy thinks that not only do the volcanoes erupt in bursts, they follow remarkably consistent patterns that range anywhere from two weeks to 100,000 years. The reason why the study is important is because it offers up the idea that undersea volcanoes may contribute to the beginning of a global warming cycle. ### See The Best Biology Photos Of The Year  Two Bisons on the Grand Prismatic Spring in Yellowstone National Park, Wyo.

Boris Barath Here’s how: Scientists believe as the Earth warms and ice melts, pressure is released which causes more land volcanoes to erupt. More eruptions means more CO2 is emitted into the atmosphere, causing the Earth to warm further and creating a cycle. But undersea volcanoes erupt for the opposite reason. When more ice is created on a cooling Earth, that lowers sea levels and relieves pressure on undersea volcanoes, bringing about more eruptions. So that begs the question, could the undersea volcanoes be releasing enough CO2 to affect the warming process on land?
