Earth’s Plate Dance Could Be a Major Climate Driver

A new study using computer models shows that Earth's plate tectonics—especially mid-ocean ridges and continental rifts—play a larger role in shaping global climate than previously thought by guiding the deep carbon cycle: carbon stored in seafloor sediments is buried and later released via subduction, driving greenhouse and icehouse periods over the last 540 million years and challenging the view that volcanic arcs are the primary CO2 source, with implications for future climate models.

Tectonic shifts steer Earth's climate more than previously thought

New computer-based reconstructions of 540 million years show that the movement of Earth’s plates—especially mid-ocean ridges and continental rifts that drive carbon into and out of the oceans, and the subsequent subduction of carbon-rich sediments—have played a bigger role in driving greenhouse and icehouse climates than volcanic arcs alone. The deep-sea carbon cycle acts as a key regulator of atmospheric CO2, influencing past and future climate and informing climate models that consider tectonic processes alongside human emissions.
