Unlocking Earth's Deep Carbon Cycle: Tectonic Plates Drive Climate Shifts

New scientific research has revealed a more complex system influencing Earth's historic climate changes than previously thought. While scientists long believed that volcanic arcs were the primary source of atmospheric carbon dioxide, new findings suggest that mid-ocean ridges and continental rifts play a vital role. This study shows that these rifts and ridges, where tectonic plates diverge, have been significant players in shaping carbon cycles over millions of years. The research underscores the process where oceanic carbon-rich rocks are subducted back into Earth's interior, releasing carbon into the atmosphere. The findings are crucial, providing insights into Earth's carbon cycle and offering a new perspective for future climate models. This knowledge is particularly pertinent given today's concerns about rising atmospheric carbon dioxide levels and their impact on global climate change. (With inputs from agencies.)
