While climate change is increasing the frequency of extreme weather events, traditional system of flood management through lakes and connected water channels has been forgotten. This makes flood and devastation inevitable.
The floodwaters devastating large parts of the Himalayan state of Jammu and Kashmir caught the people and the government unawares, it is said. But why should this be so? We know every year, like clockwork, India grapples with months of crippling water shortage and drought and then months of devastating floods. This year offers no respite from this annual cycle but something new and strange is afoot. Each year, the floods are growing in intensity. Each year, the rain events get more variable and extreme. Each year, economic damage increases and development gains are lost in one season of flood or severe drought.
Scientists now say conclusively that there is a difference between natural variability of weather and climate change, a pattern brought about by human emissions that is heating up the atmosphere faster than normal. Scientists who study the monsoons tell us that they are beginning to make that distinction between normal monsoon and what is now showing up in abnormal extreme rain events. Remember, the monsoons are known to be capricious and confounding. Even then scientists can see the change.
