Abstract
This chapter describes the nexus of Glacier Lake Outburst Flood (GLOF) and Climate change with special reference to Himalaya-Karakoram-Hindukush (HKH) region. The spatial and temporal analysis of GLOF is marked as one of the indicators to quantify the magnitude of global warming and climate change. The increase in surface temperature accelerates melting of glaciers and as a result increases the formation of glacial lakes and probability of GLOF occurrence. The HKH region that falls in Pakistan hosts numerous small and large glaciers. It is glacier milk that feed the Indus River System and support more than 200m population. In the HKH region, due to the changing climate scenario, an anomaly in glacier behavior and formation of glacial lakes has been detected that often trigger GLOF. In this chapter, Multi-Spectral Remotely Sense data have been used to detect the spatial distribution of glacial lakes, its spatial extent and the volume of water it holds during past three decades. Parallel to this, the chapter highlights the GLOF events in changing climate scenario.
