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

September global temperature falls 0.08C from August

Global temperatures for September 2018 were 0.61C based on merging GHCNV3 with HadSST3 and using spherical triangulation. This is a fall of  0.08C since August. The baseline for temperature anomalies is always 1961-1990. The annual average so far (9 months) … 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
