Global Climatic Variations And Its Impct

Globally changing climatic conditions have shown direct and indirect impact worldwide. In Indian continent drast changes have been recorded in hydrological conditions, Himalayan glaciers, agriculture production and water resources. As per the IPCC studies the amount of energy reaching the earths atmosphere every second on a surface area of one square meter facing the sun during daytime is about 1370 Watts and the amount of energy per square meter per second averaged over the entire planet is one quarter of this. In one of the most productive regions of India i.e., Ganga Plain approximately 250 million people are f Climate warming and anthropogenic pressure has greatly threatened the meteorological conditions, agricultural production and causing large hydrological variations in different parts of India and surrounding Prominent changes have been recorded in the drainage morphology, crop production and precipitation patterns. These changes are modifying the land use and land cover pattern, cropping pattern, drainage pattern and over exploitation of water resources are modifying the hydrological cycle. The frequency of floods and drought and its intensity has increased manifold. About 65% population of India is agricultural based and in the long run climate change will affect the quantity and quality of the cro already high food inflation in the country. The aim of this study is to understand the globally changing climatic conditions and its impact worldwide and on Indian continents and come up wi solutions effective it address the problem of water and food scarcity in future.
