Volcanism can not only temporarily alter the atmosphere’s chemistry, but the ash from volcanism can also block sunlight from reaching Earth’s surface and lead to atmospheric cooling. Carbon dioxide vented by volcanism in the Mesozoic era is . Tectonic plate movements can alter the circulation of the atmosphere and ocean. When continental plates come together into a supercontinent, oceanic currents can fail and the oceans can become anoxic, as atmospheric oxygen is no longer drawn into the global ocean’s depths, which may have . When continents are near the poles, , but in our current ice age the tipping point is , which is affected by, among other influences, the Moon.
