Deniers of the idea of Global Climate change citing the greater number of cold weather events ought to be given this analogy.
A refrigerator requires electricity (heat) to run the motor. That motor produce exhaust. To prove this to yourself stand behind your refrigerator. The cold generated by the heat is a compensation effect. Our Earth is encountering this phenomenon.
So the next time you encounter an “unbeliever” just tell them to go stand behind a refrigerator. And when they complain about the heat, just remind them that the hotter it gets, it will get colder soon enough!
