These two graphs show the same data: about a .7-degree rise from 1.3-2.0 in the time from the start of the industrial revolution through now. I just made these numbers up as examples, but you can manipulate a graph like this with whatever numbers you select. Somewhere there's probably a tool specifically made for zooming in and zooming out and getting the graph to look like a hockey stick or a baseball bat, depending on which "look" benefits your fake cause more.
But anyway, don't litter, okay? And check your mufflers.
