Global warming, or heating, or whatever, is only one part of a continuing cycle to climate change, both up and down in the temperature scale.
The cycle includes global cooling, or even global deep freezes, as well.
And none, NONE, of it could in any be attributed to the presence or the activities of the species Homo Sapiens.
Indeed. And the next cooling cycle (predicted to be much worse than the "Little Ice Age") is scheduled to begin in 2020!
Professor Valentina Zharkova Breaks Her Silence and CONFIRMS “Super” Grand Solar Minimum
Professor Valentina Zharkova gave a presentation of her Climate and the Solar Magnetic Field hypothesis at the Global Warming Policy Foundation in October, 2018. The information she unveiled should shake/wake you up.
Zharkova was one of the few that correctly predicted solar cycle 24 would be weaker than cycle 23 — only 2 out of 150 models predicted this.
Her models have run at a 93% accuracy and her findings suggest a Super Grand Solar Minimum is on the cards beginning 2020 and running for 350-400 years.
