New Interpretation of Antarctic Ice Cores: Prevailing Theory on Climate History Expanded

ScienceDaily (Mar. 8, 2011) â€" Climate researchers at the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association (AWI) expand a prevalent theory regarding the development of ice ages. In the current issue of the journal Nature three physicists from AWI's working group "Dynamics of the Palaeoclimate" present new calculations on the connection between natural insolation and long-term changes in global climate activity. Up to now the presumption was that temperature fluctuations in Antarctica, which have been reconstructed for the last million years on the basis of ice cores, were triggered by the global effect of climate changes in the northern hemisphere.

The new study shows, however, that major portions of the temperature fluctuations can be explained equally well by local climate changes in the southern hemisphere...

Research reveals a baseline cyclic climate change model.

The basic cyclical model is all that existed for global climate change prior to man's influence.  This does not refute the argument that man is warming the Earth.

It's not supposed to, that point is dealt with in the last paragraph of the article.
