Northern oceans pumped CO2 into the atmosphere

At the same time the pH of the surface waters in these oceans decreased, making them more acidic. Both of these findings imply changes in ocean circulation and primary productivity as a result of natural climate changes of the time. The findings were recently published in Nature Communications.Oceans changed functionToday the cold Arctic and Nordic Seas are especially efficient areas for uptake of CO2 from the atmosphere. The oceans have been capable of mitigating some of the incr
