Under the lead of the IOW, a sediment core from the Southeast Pacific was examined that reflects the last 8 million years of Earth's history. The study shows that the intensity of the Antarctic Circumpolar Current, which connects the world’s three major oceans, is particularly sensitive to temperature changes, which in turn significantly influences the exchange of CO2 between the ocean and the atmosphere. The study was recently published in the journal Nature Communications.
