Palmer Drought Index from 1895 to present, are reported by NOAA: 'Severe droughts have occurred well before 1960 and the large influx of human CO2 emissions. The droughts of 1930's & 1950's were worse than 2011/12 drought. The 30-year drought average indicates little in the way of extreme climate change - in fact, current drought conditions are well within the bounds of natural climatic variation over last 100+ years'
