At http://phys.org/print304594532.html … some new discoveries on foraminifera, the tiny shells of sea creatures such as plankton that are an important prop of Ice Age theory – and palaeo climate history in general. These shells hold clues about the composition of the sea water they lived in and Science (Nov 22nd) and Biogeoscience (Oct) provide the necessary news. Sediment cores are used to reconstruct prehistoric climate – and in the oceans of the world this involves the innocuous remains of foraminifera (plankton) shells. For example, oxygen levels in the shells are thought to show up clearly the 100,000 year Milankovitch cycle – a long cool period and a short warm period – the latter being the interglacial. This is supposed to have happened as regular as clockwork for several millions of years. It was presented as a incontrovertible fact of the consensus – you couldn't argue with the oxygen isotopes (or so we were told). It seems it was was all hooey and other factors come into play. The ups and downs are much more complex than envisaged. However, don't expect the consensus to admit the findings undermine the grand scheme – that will never happen. Never in a million of years. Pun intended.
