Dr Zaigham Habib, a renowned hydrologist said the main reason behind the change in weather patterns was warming of seas and melting of snow at the glaciers, which has increased vaporization across the globe.

“We already have less water in rivers and more rains in catchment areas”, she said and predicted that Punjab may soon see a drastic cut in its river water coming from India. “Late snow melting may also cause flash floods in the country,” she warned and said the government’s approach was to manage a disaster whereas it should be averting a disaster. Dr Habib further said that most of the coastal areas of the world were witnessing excess rains. Disasters occurred once in a blue moon but when it started occurring every year it was not called a disaster, she said.
