Volcanoes on the Ocean Floor Can Trigger Climate Change


Many scientists consider the large number of volcanoes present beneath sea surfaces as gentle structural formations that ooze magma at slow and steady rates along the oceanic ridges. But a recent study reveals that they break out on markedly expected cycles, measuring anywhere between fifteen days to 100,000 years. The study also highlights that they blow up more or less during the first half of every year. The pulses that these volcanoes generate, according to the report, are not only linked to changes in the earth’s orbital path in addition to sea level, but also act as the trigger for climate change.

Team’s conclusions call for significant changes to present day climate change models

The findings of the study, therefore, seem to suggest that representations of the planet’s natural climate kinetics as well as man-made climate change models require alterations. The research team claims the latest study is of significance, because even though scientists are well aware of the role of land volcanoes on climate change, this is the first time that the role of submarine volcanoes in triggering climate change has been established. Talking about the research, Maya Tolstoy the research’s main author and Geophysicist says, “People have ignored seafloor volcanoes on the idea that their influence is small—but that’s because they are assumed to be in a steady state, which they’re not,”

Tolstoy’s research dislodges conventional thinking and highlight new facts

Tolstoy’s study not only disapproves of the conventional wisdom that volcanoes break out at reasonably steady rate, but also highlights the fact that the volcanic ridges on the seafloor besides being calm and languid also produces large amount of magma compared to land volcanoes. Additionally, the CO2 levels that submarine volcanoes generate is less than its land counterparts, about eighty-eight million metric tons annually. The team’s conclusions find support in another related study on submarine volcanism around the Antarctic region as well.
