Climate change and its impacts are originating overall the world; especially its impact on developing countries can measure clearly. It is perilous for life of the Earth that average temperature of the Earth is slowly increasing, about 010c is increasing after 30 years. Current average temperature of the earth is 150c but between 1961 and 1990, the annual average temperature of the globe was14.0°C.(Clark,. et, al., 2004) Key impact of climate change is melting of Glaciers and it related problem is sea level rise. It is not problem of pacific, Atlantic or Indian Ocean, but almost enormous water bodies of the world are connected to each other, so that all oceans are facing this problem. Glaciers are spread on 10% area of the world and their dominancy is able to see on the peaks of Mountains. The best evidence of the melting Glacier is Mountain Kilimanjaro in Africa; it is near the Equator and highest peak of any continent at equator as shown in (Fig. 1)
The climates of coastal areas of Thatta, Badin and Indus plain greatly affect the lives of people living there because this climate provides suitable environment as well as employment opportunity to the people lives there. These coastal areas are the trade center where ships from other countries came with the trade products which increases the opportunity of jobs for the people there so that's why we can see large population on these coastal areas due to their climate and employment opportunities.
