And very old.
Himalayan glaciers melting for 400 years, finds BSIP study.
We should probably retreat to a pre-Copernican understanding of the solar system, too, just to be safe. Because Himalayan glaciers.
Melting of glaciers is not only caused due to industrialization and global warming but natural factors like oceanic currents and total solar irradiance (TSI), which means total sun energy coming to earth, are equally responsible. Oceanic currents affect monsoon and since glaciers are dependent on monsoon precipitation in the form of snow, any change in it affects glaciers. TSI affects temperature and other climatic factors which affect glaciers.
A study by a team of nine scientists from Birbal Sahni Institute of Palaeosciences has unfolded the health status and behaviour of Himalayan glaciers over a period of four centuries.
The scientists used tree ring data of around 400 years from Himalayan conifers in the glaciated valleys of Uttarakhand, Himachal Pradesh and Kashmir for research.
The study has been published in the prestigious international journal ‘Scientific Reports’ of Nature group.
“Glacier melting has been an area of great concern, as glaciers are huge water reservoirs and a source of fresh water. Our study highlights the loss in volume of the Himalayan glaciers and shows that even when European glaciers were expanding, Himalayan glaciers were shrinking,” said senior scientist Parminder S Ranhotra.
Ranhotra added that there is no instrument to measure glacier health over such a long period of time.
Huh. It's almost as though we don't even know all the things we don't know.
But we'd better ban and tax the hell out of some stuff, just to be safe.
