Wow. Rivers froze. That is nothing compared to what is coming. No country has ever survived a full blown ice age.
Who is claiming an imminent ice age?
What is being claimed is an imminent, like starting today, Maunder-like minimum (aka, Eddy minimum, aka ManBearPig minimum) and lasting thru the next 75-150 years.
The next ice age is probably on schedule, to hit in about 10,000 years.
