“Glacier melting has no effect on river flow. Rivers do not dry out,” said a new study. However, several studies in the past have suggested that glaciers are melting. Glaciers have been melting since the last ice age ended 11,700 years ago, but have been receding.
Surprisingly most glaciers were stable between 2001-2011 under ISRO satellite monitoring. But some are moving forward in regression. Of the 2,018 glaciers monitored by ISRO, 1,752 were found to be stable, 248 to recede and 18 to move forward.
“Scientists are often concerned about the melting of the Gangotri Glacier, the holiest of the Hindus. The 30 km long glacier is the second largest in the Himalayas. It will take 3,000 years, ”the paper said.
The media and environmentalists have exaggerated the speed and consequences of the glacial recession. It is noteworthy that the IPCC later withdrew this statement.
Co-author VK Raina studies show that glacial recession has been declining in recent years despite rising temperatures. ‘People who issue warnings that glaciers are melting are actually playing games,’ the authors were incensed. No study carried out so far has been able to distinguish between ice, glacier melting and rainfall for river flows.
However, the latest study explains this for the first time. ‘Glacier melting is only one per cent of the Indus flow .. even lower than the Ganges and the Brahmaputra. 94% of the rainfall contributes to the flow of the Ganges. The study suggests that the area covered by winter snow is much larger than glaciers and contributes many times more.
