These are the ice core temperatures from Greenland. Global Warming is the uptick at the left. Please, note that it is less than the peak 1000 years ago, which is when Vikings were populating Greenland. Please, note, too, that the temperatures since the last ice age have for the most part been higher than the current temperatures. These higher temperatures are known as the Holocene Optimum, which you don't hear much about from the Warmistas. It clearly illustrates with data that man-made global warming is a ploy to grab government funds--and not related to anything scientific. That's technical for "AGW is BS!"

The graphic has an indicator called the 8.2 Kiloyear Event. It was not part of the point I was making, but it is where I obtained the graph. For those interested, more information can be obtained:
