Read here and here. Despite what climate models and climate alarmist scientists predict, global warming regimes experience less climatic variation (less floods, less droughts, less severe weather events, etc.). Nor does increased levels of CO2 cause more erratic and violent weather. The principal driver of more severe weather and climatic conditions is the temperature difference between polar and tropic areas. Global warming reduces the temperature difference between these two geographical regions.
The climate and weather stability of warmer periods, relative to colder periods, was further documented by extensive research of Chinese historical documents and reports. (click image to enlarge)
"Flood and drought histories of the past thousand years in China's Yangtze Delta were developed, according to the authors, "from local chronicles, old and very comprehensive encyclopaedia, historic agricultural registers, and official weather reports." Thereafter, "continuous wavelet transform was applied to detect the periodicity and variability of the flood/drought series" -- which they describe as "a powerful way to characterize the frequency, the intensity, the time position, and the duration of variations in a climate data series"...."Contrary to climate-alarmist contentions that warmer temperatures lead to more frequent and intense floods and droughts, this evidence from China suggests just the opposite. In addition, the proxy temperature records employed by Zhang et al. indicate that the warmest 50-year periods of the past millennium occurred during the Medieval Warm Period and not during the 20th century in both temperature histories, which is also just the opposite of what climate alarmists typically contend for most of the world."
