Any which way you look at global drought measures in the last 120 years this is not the CO2 doom scenario of the IPCC prophesies either in rainfall patterns or in water supplies. The graphs below show rainfall trends shifting slightly due to unknown forces and looking for all the world, like CO2 is irrelevant. Despite the scare campaigns about floods and droughts, and the threats of climate wars over dwindling rivers, there has been no trend in hydrological droughts since the Wright Brothers first flew a plane.
Kenneth Richards at NoTricksZone reported on Shi et al, a paper which looked at trends from 1902 to 2014 in all nine climate zones of the world.
The first graph shows a mixed bag of trends in Meteorological Droughts, none of which are obviously linked to human emissions of CO2. Remember, half of all human emissions since we crawled out of caves has been emitted after 1995. According to CDIAC fully 250,000 Mt of CO2 was emitted up to that year, then we have doubled that in the years since then. If CO2 was a planet transforming molecule, surely we’d see something in the last 25 years?
