Towards an understanding of Ice Ages

An Ice model driven by NH insolation but adjusted for dust albedo does a pretty good job at reproducing the last 8 glacial cycles. Details are described below. Prior to the Mid Pleistocene Transition (MPT) roughly one million years ago,  … Continue reading

The Milankovitch Puzzle

The main focus in understanding Glacial cycles has been on the maximum summer insolation at 65N, yet prior to MPT (Mid Pleistocene Transition) all glaciations simply followed the obliquity cycle. To understand why obliquity is the underlying metronome, we need … Continue reading

Ice Age insights

The discussion on the ‘dust’ theory of ice age termination at Judith Curry brought a couple of other interesting papers to light. This has started me thinking again about how recent deep glaciations terminate. Such glacial cycles apparently now only … Continue reading
