Singh et al. (2016) published a geochemical record of sediment compositions from the
flood plain of the Ghaggar River in western India and use the changing provenance,
particularly as traced by Nd isotope composition, to reconstruct how erosion patterns
have changed over the past 100 k.y. In doing so they propose a link between climate
change and erosion, and they argue for more erosion from the Higher Himalaya during
warmer interglacial periods and more from the Lesser Himalaya during glacial intervals.
While we support the concept of erosion patterns being climatically modulated we here
take the opportunity to compare the data presented by Singh et al. (2016) to relevant published records within the region greater Ghaggar region and to open a balanced
discussion on how climate and erosion are coupled in the western Himalaya.
