co2 and C14

4 October 2011
Climate change

Sediment cores off the coast of Oregon have revealed that the NW Pacific was not a huge reservoir of co2 during the last Ice Age and could therefore not have hastened the rate of warming – see www.physorg.com/print236864292.html. The paper, published in Nature Geoscience, is somewhat baffling, it claims, as the Pacific,nowadays, is thought to be rich in carbon. Indeed, a recent paper alleged that the missing heat was hiding in the oceans – especially in the Pacific. Whilst it was painfully obvious to many that this theory was an attempt to keep the CAGW meme on track rather than a realistic situation, this study therefore is of interest as the deep Pacific does not seem to have been a sink for co2 during the last glacial. In addtion, the research discovered that organisms living on the sea floor have older C14 ages than organisms living near the surface, even though both came from the same sediment sample and are of the same true age. Different sources of co2 have different ages – it would seem. Undersea volcanism may have contributed to the older C14 dates – and Douglas Keenan is on record as suggesting old carbon from the Thera eruption may have contributed to older C14 dates across the eastern Mediterranean and Near East. However, this is conjecture and is as yet unproven – if anyone has actually attempted to, so far. In this instance, the difference is said to derive from isolation from the atmosphere. It is speculated that co2 rose dramatically at the end of the Ice Age giving rise to further warming – but where did it come from if not from the oceans?
