C02 and the Oceans

19 Jun 2010

At www.physorg.com/print196059921.html June 18th ... in looking at ice cores from up to 800,000 years ago scientists have found a link between ice melt and C02 abundance in the atmosphere. There has been a 40 per cent increase of C02 in the atmosphere since the last glaciation - and this can largely be attributed, it is being said, to changes in the circulation of oceanic waters surrounding Antarctica.

Meanwhile, at www.physorg.com/print196074751.html there is a piece on the Ocean Conveyor Belt System which is thought to transport deep polar water towards the equator or warm equatorial water to the poles - along a narrow system of currents. In the June 18th issue of Science an oceanographer suspects the conveyor belt system requires a rethink as it is out of date - new findings mean it requires an overhaul. The current model, somewhat surprisingly, ignores the role of wind above the waves - and what else might it ignore?
