“…In the Western Himalaya, analyses of peat-lake sediment from small lake sited on a moraine from the Chandra valley in India indicated prominent cold-dry event at 1303-1609 CE (Rawat et al, 2015). On the Tibetan Plateau, analysis of the timing of lake formation and drying and the southward migration of trees and grassland indicate generally wetter-than-present conditions during the LIA, followed by drying during the 20th Century greater than at any time since 1200 CE (Putnam et al, 2016).…”

Northern Hemisphere cooling between 1400 and 1900 in the Common Era (CE) resulted in the expansion of glaciers during a period known as the 'Little Ice Age' (LIA). Early investigation of recent advances of Himalayan glaciers assumed that these events were synchronous with LIA advances identified in Europe, based on the appearance and position of moraines and without numerical age control. However, applications of Quaternary dating techniques such as terrestrial cosmogenic nuclide dating have allowed researchers to determine numerical ages for these young moraines and clarify when glacial maxima occurred. This paper reviews geochronological evidence for the last advance of glaciers in the Himalaya. The 66 ages younger than 2000 years (0-2000 CE) calculated from 138 samples collected from glacial landforms demonstrate that peak moraine building occurred between 1300 and 1600 CE, slightly earlier than the coldest period of Northern Hemisphere air temperatures. The timing of LIA advances varied spatially, likely influenced by variations in topography and meteorology across and along the mountain range. Palaeoclimate proxies indicate cooling air temperatures from 1300 CE leading to a southward shift in the Asian monsoon, increased Westerly winter precipitation and generally wetter conditions across the range around 1400 and 1800 CE. The last advance of glaciers in the Himalaya during a period of variable climate resulted from cold Northern Hemisphere air temperatures and was sustained by increased snowfall as atmospheric circulation reorganised in response to cooling during the LIA.

“…Evidence suggests that the upper Satluj valley (higher and trans-Himalaya) experienced large landslides and LLOFs, during extreme precipitation events, around 14-7; 7-5, and ~3 ka (Bookhagen et al, 2005;Anoop et al, 2012;Draganits et al, 2014). Also, in present times the terrain witnesses landslides and LLOFs during extreme precipitation events (Sharma, 2006;Gupta andSah, 2008a, 2008b).…”

Despite a large number of dated glacial landforms in the Himalaya, the ice extent during the global Last Glacial Maximum (LGM) from 19 to 23 ka is only known to first order. New cosmogenic 10Be exposure ages from well‐preserved glacially polished surfaces, combined with published data, and an improved production rate scaling model allow reconstruction of the LGM ice extent and subsequent deglaciation in the Chandra Valley of NW India. We show that a >1000 m thick valley glacier retreated >150 km within a few thousand years after the onset of LGM deglaciation. By comparing the recession of the Chandra Valley Glacier and other Himalayan glaciers with those of Northern and Southern Hemisphere glaciers, we demonstrate that post‐LGM deglaciation was similar and nearly finished prior to the Bølling/Allerød interstadial. Our study supports the view that many Himalayan glaciers advanced during the LGM, likely in response to global variations in temperature.
