GreenTracker| Researchers hoped that one of the side-benefits of the metling of the Arctic Oceam might be an increase in CO2 absorption. Researchers studying the Canadian Basin, which extends north of Alaska to the North Pole, confirms that it probably has little value as a carbon dioxide “sink”.
As the ice melts, the carbon dioxide in the water very quickly reaches equilibrium with the atmosphere, so there’s little added benefit of the oceans storing extra CO2.
The carbon dioxide level in the Earth’s atmosphere has increased dramatically since the industrial revolution, and around 30 percent of that CO2 has been absorbedby the oceans. That has been the good news. The bad news is that it increases the acidification of the seas, causing changes in conditions for the growth of all life forms. via Science Daily
