Fact #21

IPCC models have overstated warming up to three times too much.

A detailed examination by John Christy, a distinguished climatologist at the University of Alabama at Huntsville and Alabama State Climatologist, provides a stark assessment of the validity (or non-validity) of the models that are used in support of imagined apocalypse. His testimony in February 2016 to the U.S. House Committee on Science, Space & Technology included remarkable charts that document just how much the models overestimate temperatures. The red line in the chart shows the average of 102 climate model runs completed by Christy and his team at the University of Alabama at Huntsville using the models on which the IPCC itself relies. Also shown on the chart are the actual, observed temperatures. The models exaggerate warming, on average, two and a half times the actual temperature (or three times over in the climate-crucial tropics).

The Great Climate Change Debate is one of the “hottest” issues before the public and policy makers today. How much to you know about the subject? Or possibly, the real question is one attributed to American humorist Will Rogers:

“It ain’t what you don’t know that gets you into trouble. it’s what you know for sure that just ain’t so.”
