Climate change in India

India is ranked fourth among the list of countries most affected by climate change in 2015. India emits about 3 gigatonnes (Gt) CO_2eq of greenhouse gases each year; about two and a half tons per person, which is less than the world average. The country emits 7% of global emissions, despite having 17% of the world population. Temperature rises on the Tibetan Plateau are causing Himalayan glaciers to retreat, threatening the flow rate of the Ganges, Brahmaputra, Yamuna and other major rivers. A 2007 World Wide Fund for Nature (WWF) report states that the Indus River may run dry for the same reason. Heat waves' frequency and intensity are increasing in India because of climate change. Severe landslides and floods are projected to become increasingly common in such states as Assam. The climate change performance index of India ranks eighth among 63 countries which account for 92% of all GHG emissions in the year 2021.

Temperatures in India have risen by 0.7 °C (1.3 °F) between 1901 and 2018.

According to some current projections, the number and severity of droughts in India will have markedly increased by the end of the present century.
