Changing Climate of Uttarakhand, India

Ashutosh Mishra

India has a unique climate system dominated by the monsoon, and the major physiographic features that drive this monsoon are its location in the globe, the Himalayas, the central plateau, the western and Eastern Ghats and the oceans surrounding the region. The country is considered highly vulnerable to climate change, not only because of high physical exposure to climate-related disasters, but also because of the dependency of its economy and majority of population on climate-sensitive sectors (e.g. agriculture, forests, tourism, animal husbandry and fisheries). The Himalayan Region comprises of the highest mountain system of the world, the Himalayas and the North- Eastern hill states. Being the home of some very large and important glaciers (viz. Gangotri, Ponting, Milam, Pindari etc) the state of Uttarakhand has remained in centre of climate change discussions since over three decades. In addressing this debate and to eliminate confusions, the paper examines emerging climate trend scenarios in the region by measuring temperature and rainfall variabilities during the past century. The results indicate unanimous warming of the entire region but are more critical in mountainous parts. On the other hand the plain areas have received more rainfall, while it has declined in hilly districts.
