IQ & Global Inequality

What struck me is I have finally found evidence that northern climates are correlated to intelligence, better education, greater wealth. For every degree north, temperature falls by 0.885 degree celsius. National IQ rises by 0.677, quality of life as measured by QHC increases by 0.659, GNI per capita up 0.528, adult literacy rate up 0.482, tertiary enrollment ratio up 0.718, life expectancy at birth up 0.505.
