The bottom line is, we are still in the Quaternary. (No one has presented any real physical evidence to the contrary!) The Quaternary is a geologic age characterized by cyclic continental glacial ice sheets. The last glaciation ended roughly 22,000 years ago. Its coming back, its just a matter of when. There is nothing we can do about it other then do what man did the last time! Migrate to warmer climes!
No, I'm afraid this report isn't 'crying wolf'. The data has been confirmed by real climatologists and even astrophysicists going back a quarter century.
The impending cold era is what's called a grand solar minimum. These periods of intense cold occur about every 400 years and can last from thirty to seventy years.
The coming solar minimum even has an official name. It's called the Eddy Minimum, in honor of the climatologist who first predicted it.
