For example I read about the work of Dr. Alexei Dmitriev, near 10 years ago... His work was confirmed by report of voyager space probe since...then discussion about the real causes of climate changes are not news to me at all...I can go on but the attention span of news papers readers tend to be short...And the climate changes ask for many articles, books, and thinking...
At the times ostriches can deny easily reality without being stupid... "Times are changing" says I dont remember who...
For the influences of the sun on world population, I will pick an old paper(1918), by William James Sidis, a man no one dare to call stupid, who in a short study show some evidences...This is fun to read, and if you dont know him, his life is stuff for science fiction books only...
If you linked Dr. Dmitriev study with the Sun cycles influences on climate and people, showed By Sidis you will know why people are crazier than ever now...Because of these coming changes...
But the real news is this one and this one is no more a theory like Sidis or Dmitriev but hard scientific measured fact that gives confirmation to Sidis and Dmitriev:

«The strength of Earth’s magnetic field in the past, recorded by rocks and sediments, provides a proxy for past flux of ultraviolet radiation (UVR) to Earth’s surface due to the role of the field in modulating stratigraphic ozone. About 40,000 years ago, mammalian fossils in Australia and Eurasia record an important die‐off of large mammals that included Neanderthals in Europe. In the Americas and Europe, a large mammalian die‐off appears to have occurred ~13,000 years ago. » to be continued in the link just on top
Climate on earth and crowds ostriches psychology is unexplainable out of this link to the sun and to the general condition of the solar system...
