LAST month at the South by Southwest (SXSW) Music Festival, Al Gore said that we should “punish climate-change deniers.”

Since then “accepted science” appears to have a bit of a problem.  It seems that global warming is indeed man-made.

That is, men–scientists actually–made it appear with a few slight edits of raw sensor data.  They configured a few inconvenient warmer data points from the 1950s downward. Not to mention tweaking a few inconvenient cooler data points in the 2000s upward.

This article by the London Telegraph’s Christopher Booker provides some excellent examples of data chicanery with before and after charts.
