There’ve been 20 periods of glacial advance ~ we are about 5,000 years overdue for the 21st period.

Until someone can explain to me about the Medieval warm period, the time when the coast of Greenland was green, it’s hard to believe all this crapola. Greenland became much more icy after medieval times. Are we to believe that the Medieval warm period was due to the Vikings driving SUVs around Greenland??????

Haven’t we been in a long term warming period since the end of the last ice age?

Did Neanderthals and Cro-Magnon man drive SUVs and have coal fired power plants?

Since so many climate changes happened before the Industrial Revolution, the global warming pushers have lots to explain. And we know how they explain things. They falsify the climate records to “prove” whatever they want to prove.

Would you be kind enough to share the data source of “20 periods” and “5,000” years. Thanks....

"There’ve been 20 periods of glacial advance ~ we are about 5,000 years overdue for the 21st period." From what I have read ice ages happen about every 100,000 years and interglacials last about 11,500 years. It's been right about 11,500 years since the beginning of the current interglacial so I am expecting the next ice to start any time.
