Jo Nova has a history of making really, big earth shattering claims on her blog that “demolish” the “myth of AGW”. This week, she uses an old National Geographic article to show how climate data must have been “doctored”:
“Frank Lansner has found an historical graph of northern hemisphere temperatures from the mid 70’s, and it shows a serious decline in temperatures from 1940 to 1975. It’s a decline so large that it wipes out the gains made in the first half of the century, and brings temperatures right back to what they were circa 1910. The graph was not peer reviewed, but presumably it was based on the best information available at the time. In any case, if all the global records are not available to check, it’s impossible to know how accurate or not this graph is…”
Nova has an interesting point, and in the fine tradition of her reasoning I can now prove – yes prove – the Sun goes around the Earth! Apparently astronomers in the 16th Century had a very good idea of how the solar system was actually arranged:
What else are those scientists hiding! Demand the truth! Question everything!
Yes Jo, because the methodology of science and collection of data have not changed since the 1970’s. Is that the best the denial movement can do? I mean, really?
It’s like they’re not even trying anymore.
File this under hunting for anomalies.
