also, the entire idea of global temperature is just not useful the precession of the earth is what matters on earth why are there so many stone monuments that point to the 22K year cycle ? and they could have pointed to any point on that cycle, so why point to our point in time now ? and why do archaeologists keep finding a 10500 year extinction cycle that also lines up with our time now as the next one ? not to hard to figure out... this is why the idea that global temperature matters is a scam. one hemisphere or the other is warmer, this is what matters. when the ice melts in one half and moves to the other half, the entire earth shifts just a bit... just enough to wipe out entire civilizations. no wonder why they build monuments to the next transition date in stone around the globe.
