What an ingenious way to show the difference between how global warming deniers look at temperature trends versus how climate scientists look at the info (h/t Climate Denial Crock of the Week):
I also always love this one from Skeptical Science, too:
Berkeley Earth Surface Temperature (BEST) land-only surface temperature data (green) with linear trends applied to the timeframes 1973 to 1980, 1980 to 1988, 1988 to 1995, 1995 to 2001, 1998 to 2005, 2002 to 2010 (blue), and 1973 to 2010 (red).
And, hey, while we’re at it, why not one more on the subject (from the same Skeptical Science page):
Temperature data (with a 12-month running average) before and after the short-term factor removal
