India was ranked seventh among the list of countries most affected by climate change in 2019.[1] India emits about 3 gigatonnes (Gt) CO2eq of greenhouse gases each year; about two and a half tons per person, which is less than the world average.[2] The country emits 7% of global emissions, despite having 17% of the world population.[3] The climate change performance index of India ranks eighth among 63 countries which account for 92% of all GHG emissions in the year 2021.[4]
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.[5] Severe landslides and floods are projected to become increasingly common in such states as Assam.[6] Heat waves' frequency and intensity are increasing in India because of climate change.[7] Temperatures in India have risen by 0.7 °C (1.3 °F) between 1901 and 2018.[8]
According to some current projections, the number and severity of droughts in India will have markedly increased by the end of the present century.[9]
