"Using the Last Ice Age to Predict Global Ocean Response to Warming"

A study led by a Tulane University oceanographer has found that deposits deep under the ocean floor can be used to measure the ocean's oxygen level and its connection with carbon dioxide during the last ice age, shedding light on the role of oceans in past glacial melting cycles and potentially improving predictions of how ocean carbon cycles will respond to global warming. The research reveals a correlation between global ocean oxygen contents and atmospheric CO2 from the last ice age to today, highlighting the critical role of the Southern Ocean in modulating atmospheric CO2. The study's findings could have implications for understanding how the ocean, particularly the Southern Ocean, will dynamically affect atmospheric CO2 in the future.
