As anyone who has read my posts knows, I am a critic of the science backing the Hansen Hypothesis that Anthropomorphic CO2, if unabated, is going to cause catastrophic global warming. I strongly favor joining the Paris Accord and alternative energy research for reasons other than the Hansen hypothesis.
I have said rather unkind things about Hansen, which I believe are well deserved. He , as a scientist should know better, and I think he owes all of us an apology for his very non-scientific conduct.
The paper linked to above presents what in my opinion is the best hypothesis so far advanced to explain long term climate fluctuations on planet Earth. Unlike the Hansen Hypothesis, it is at least, so far, consistent with all observations. A single observation that is inconsistent with an hypothesis must be either proved incorrect or the hypothesis must be rejected. Numerous observations, and theoretical considerations too, are inconsistent with the Hansen Hypothesis.
If Shaviv's hypothesis becomes widely accepted as correct he will no doubt share the Nobel Prize with his colleague, and it will be well deserved.
Every now and then a bright creative scientist breaks with conventional thinking to establish new scientific frontiers. It would seem Shaviv is such a scientist. I have known of his work for several years but this 2015 paper makes it somewhat accessible to the general public.
