It is always baffling to me that the ignoramuses, despite having it explained to them many times, somehow are incapable of understanding the simple concept of average global temperature. Global warming means that this very average global temperature is evidentially (as in, HAS BEEN FUCKING MEASURED) rising. It does not mean that it gets warmer everywhere at the same rate, because the complexity of climate means that the rise of the global average temperature can wreak havoc in different parts of the world and cause local spikes in either direction.
