Impact of Changing Climate on the Cryospheric Region and Glacier Retreat in the Himalayan Region

The concentration of greenhouse gases in the air is gradually rising because of human activity and industrialization, leading to global warming and climate change. Climate change and global warming will affect temperature and other factors, including precipitation intensity and amount, cloud shelter, breeze, and radiation. The melting of ice sheets and glaciers throughout the planet is a sensitive and obvious sign of the global average temperature rise scenario. Sea-level rise (SLR), mountain-fed river hydrology, the freshwater balance of the seas, natural catastrophes, and even the Earth’s physical attributes (rotational behaviour and shape) are just a few examples of processes that may be directly impacted. The faster pace of retreat compels us to consider the other elements influencing it right now, even if glacial evacuation is a natural occurrence caused by the earth’s transition to a warmer phase. This chapter discusses the impact of changing climate on the Cryospheric Region and the glacier retreat in the Himalayan Region. The chapter highlights the immediate and long-term consequences of glacier retreat, including rising sea levels, water availability changes, and threats to local communities and ecosystems. The chapter also presents case studies from the Himalayan region, including the Dokriani, Chhota Shigri, Satopanth and Bhagirath Kharak, and Milam glaciers, to illustrate the influence of climate change on glaciers and the surrounding areas. Finally, the chapter concludes that immediate and concerted action is essential to mitigate the special effects of climate change on glaciers in the Himalayan region and ensure the sustainability of the natural resources and communities.
