As the reconstruction of the climate’s development in the past by proxy data shows, there’s a series of temperature cycles that appear to be unknown, or ignored by many climate scientists. Among these are the larger climate cycles of 150 million to 180 million years (see Part 1 and Part 2), but also the shorter and for us the more important following cycles:

1000 years (900-1100)    Suess cycle with +/-  0.65°C
230 years (230-250)        deVries cycle with +/-  0.30°C
65  years (60-65)              Ocean cycles with +/- 0.25°C
