In the seventies it was global cooling
We are in the midst of a Maunder Minimum. Expect a mini ice age
a BIG ten four.
Real climatologists are fully aware of the fact that the sun is entering a quiet phase, that will bring about a strong cooling trend, also known as a solar minimum.
The impending minimum is already in progress, but the most visible effects won't become apparent for another year or two.
It even has a name. It's called the Eddy Minimum.
