New paper shows no correlation between CO2 and rainfall: ‘Another tenet of AGW theory bites the dust in the face of real-world data’
'AGW theory proposes that increased CO2 levels lead to increased water vapor in atmosphere (despite empirical data which shows the opposite). A paper published in Nature Climate Change February 2012 studied rainfall over Indian subcontinent 1813-2006 & finds rainfall has decreased since 1930s as CO2 emissions markedly increased. The data instead shows a natural, cyclical variability in mean annual rainfall that peaked in 1870s and 1930s with absolutely no correlation to levels of CO2'
