Historical facts: The winter of 1942 was the coldest on record across all Europe. This was the time when the Russians were getting the upper hand against the German invaders. The Germans Army was not prepared for this type of cold.

The Summer of 1943 set records for extreme heat all across Europe. 

The point here is that you have to go back several tens of thousands of years to determine the average temperature of the earths climate. The record breaking hot and cold temperatures in 1942-43 were only fluctuations in the climate. As others have noted, radical Left wing politicians who want to impose a World Government run out of Brussels  is the real driver behind this man made climate change scam.
