Originally uploaded to https://www.youtube.com/watch?v=ulWvj49kef4 by Tony Heller US temperature graphs released by government agencies, bear no resemblance to the underlying thermometer data. These graphs are released without warnings or disclaimers that the data has been altered. There is an error at 7:50. I showed the wrong graph for a few seconds, though I doubt anyone would notice or care if I didn't point it out.
