I agree with Milankovic except that he assumes the sun is static. The sun is far from static. The sun goes through cycles like it is breathing. We are entering a long solar minimum, like the end of an exhale. The next solar maximum will be in 2024. Sunspot activity is increasing. The Schumann Resonance is doubling and tripling intermittently with increasing frequency.
I am 50 years old. When I was young the sun was yellow, now it is white and I burn faster.
I included some links for further review.
