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.
The good news is we still have real scientists... the bad news is they're telling the truth.
