I’m listening to the Real Science Climate Conference in Paris and I was particularly interested in this graph from Dr Soon:
This suggests the the large 60year cycle which I’ve previously mentioned are based on orbital changes of the Sun. As such:
- This now explains the largest change in Climate in the 20th century and now means that unexplained variation (that could be attributed to CO2) is now insignificant. As such (if this work holds up) from asserting “no evidence 20th century warming was human”, I will be able to say “there is strong evidence it was not human”.
- If this work holds up, it suggests the future global temperature is predictable – unfortunately Dr Soon did not provide a direct comparison graph instead I spotted this:
Note the sharp decrease in summer temperature from 2000!! Unfortunately it doesn’t show the 60 year cycle – but it does suggest relatively sharp cooling of northern summers!

Kepler knew about 400 years ago that Jupiter-Saturn conjunctions return to almost the same position after every three, which is nearly 60 years.

We don’t seem to have advanced very much since then in understanding solar-planetary cycles 🙁
