Looking back through the lens of human history, the 1931 China Central Plains floods at the top of this list epitomize the sheer destructive power of nature. Estimates of the death toll range widely from hundreds of thousands to nearly four million; even using conservative figures, the scale of loss is equivalent to erasing an entire medium-sized city. A striking comparison: the disaster affected over 25 million people—roughly one-twentieth of China's total population at the time—exerting an impact on society that far surpassed many contemporary wars. While modern advancements in disaster mitigation and warning systems have reduced the frequency of such 'mass casualty' events, the destructive nature of extreme climate change is now shifting toward causing 'precision-strike' levels of economic and infrastructure damage.
