The post-IPCC AR6 (Assessment Report 6) update is a peer-reviewed scientific study.
It provides the latest assessment of India’s observed and projected climate changes.
It builds on the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6) by using new observational data and advanced climate models specific to India.
The report notes that India’s average temperature increased by nearly 0.9°C during 2015–2024 compared to the period 1901–1930.
The hottest day of the year in Western and Northeast India has warmed by 1.5–2°C since the 1950s, leading to more frequent and intense heatwaves.
Southwest monsoon rainfall has become erratic, with a decline in the Indo-Gangetic plains and the Northeast.
Extreme rainfall events have intensified in central India and coastal Gujarat.
The tropical Indian Ocean is warming at 0.12°C per decade.
This warming is causing marine heatwaves to increase from 20 days per year in recent decades to nearly 200 days by 2050, threatening coral reefs and fisheries.
The Hindu Kush Himalaya glaciers, known as Asia’s “water towers,” are melting rapidly.
Glacier volume is projected to reduce by 30–50% by 2100 under 1.5–2°C of global warming.
Arabian Sea tropical cyclones have become stronger, with maximum cyclone intensity increasing by 40% in recent decades.
