IT is always dangerous to use a proxy measure to make assumptions about a relationship. At popular blog The Blackboard, Zeke has used the Irish population as a proxy for the population of Leprechauns …given that Leprechauns are invisible thus cannot be counted accurately.
“After retrieving the historic population of Ireland from Wikipedia which, despite its obvious pro-AGW bias due to the efforts of that disreputable scallywag William Connelley, has good data on other subjects. I plotted Irish population and GISS temperature data from 1930 to present, and the results were astounding!”
Yes, the chart shows a good correlation between the proxy for the number of Leprechauns and global temperatures. But hey, correlation is not causation, so maybe Leprechauns don’t cause global warming.
