In Senate testimony, and then in numerous presentations, Dr. Michaels claimed that the actual pace of global warming was falling far short of Dr. Hansen’s predictions. As evidence, he presented a chart supposedly taken from a 1988 paper written by Dr. Hansen and others, which showed a curve of rising temperatures considerably steeper than the trend that has actually taken place.
In fact, the chart Dr. Michaels showed was a fraud – that is, it wasn’t what Dr. Hansen actually predicted. The original paper showed a range of possibilities, and the actual rise in temperature has fallen squarely in the middle of that range. So how did Dr. Michaels make it seem as if Dr. Hansen’s prediction was wildly off? Why, he erased all the lower curves, leaving only the curve that the original paper described as being “on the high side of reality.”
