Abstract
nThe study provides an overview of the relation between climate change and its harsh consequences, and thereby revealing evidence of extremes conditions such as drought. Lake Mead of USA is one such example which is a readily contracting lake. The reason is fast temperature increment, human exploitation, etc. therefore leading to jeopardized and devastating effects on life structure. GIS and Remote Sensing has emerged as an extraordinary key instrument for generating worldwide scientific information identified with different geo-environmental issues. Multi-temporal Landsat satellite imageries and meteorological data of 1987, 1997, 2007 and 2020 are adopted in the study. The Modified Difference Water Index (MNDWI) is taken into consideration. Reported reasons behind the shrinkage are the tenacious dry season and overusing the lake water. The average precipitation of the lake during 1985–2015 is 1.4mm, and average annual temperature of Arizona is 33.34 °C and the temperature can go up to 40°C; extreme temperature and less rainfall leading to drought. The water inflow Colorado River has been less while the lake’s outflow has been more, as most of the water evaporates due to high temperature. The consequences of overcharged water, intensified by the effects of climate change, are starkly visible in the “bathtub ring” of white minerals on the shores of Lake Mead, showing its decline from its highest water levels. If not looked into the matter, the temperature of the region would increase by 3°C. Protection of a lake from pollution or degradation is a major aspect of development as concluded.
