Cities like Kolkata, Shanghai and Dhaka are highly vulnerable to rising sea level due to climate changes as they are located in the coastal areas, said RK Pachauri the chairperson of the Intergovernmental Panel of Climate Change (IPCC) in Kolkata on Saturday.
"These cities, with huge population, are mega deltas, and they are likely to face the impact of climate change," Pachauri told media persons on the sidelines of the convocation at the Indian Institute of Management-Calcutta.
He said the matter has to be taken up in all seriousness. "Scientific factors are evident. We cannot keep our eyes shut." he said.
Earlier, delivering his convocation address, Pachauri said: "Partial loss of ice sheets on polar land could imply metres of sea level rise, major changes in coastline, and inundation of low lying area, with greatest effects in river deltas and low-lying areas".
