Such outbursts may take place when glacial lakes caused by melting glaciers form behind moraines and ice dams. Meltwater from shrinking glaciers is creating vast lakes that could eventually pose an enormous flooding threat, says newly published research. Global warming is speeding up melting and disrupting weather patterns that can bring too much or too little rain to the mountains. glaciers are retreating at a startling rate in the Himalayas and the major causal factor has been identified as climate change (Ageta and Kadota, 1992; Yamada et al., 1996; Fushinmi, 2000).

This region is the source of 10 major river systems, including the Brahmaputra, Ganges, Indus and Mekong, which are economic engines of the region. The UN climate panel said in a landmark 2019 report the high mountain glaciers in the Hindu Kush Himalaya region, which provide water for about two billion people, are melting quickly and this could accelerate unless mankind makes deep cuts in greenhouse gas emissions. Rapid melting of glaciers has resulted in the formation and expansion of moraine-dammed lakes, creating a potential danger from glacial lake outburst floods (GLOFs). Answer: the relationship is between melting of glaciers in floodwaters because when the ice melt it turn into water and conduct floods. redistributed or derived from. As glacier ice melts, it can collect in large glacial lakes, which are at risk of bursting their banks and creating deadly flash floods downstream in places like Hassanabad. He termed melting glaciers a severe threat to the local population and issued necessary instructions to relevant authorities for tackling any such situation. Last year, Greenland set a new record for ice loss, shedding the most mass from its giant ice sheet in any year since at least 1948. Now, their relationship is unraveling as pollution and global warming cause the Ultar glacier to melt and form unstable lakes that could burst their icy banks at any moment.
