Islamabad/Gilgit, Mar 06: Thirty-six glacial lakes in various valleys of Gilgit-Baltistan have been declared dangerous. At least seven of them pose a major threat to the people, said a survey by Focus Pakistan, an NGO. After conducting the survey, experts attending a seminar in Islamabad said Gilgit-Baltistan is highly vulnerable to climate change. The surge of the Khurdopin Glacier in Shimshal Valley, Hunza, and the formation of a lake, has emerged as a major cause of concern for geologists and local residents.
