What This Article Covers

1.An IITM-Pune study projects India's living forest carbon will rise from 7.74 kgC/m² historically to 13.67 kgC/m² under high emissions by 2100.

2.Rainfall variability is the dominant national-scale driver of forest carbon changes, with effects lagging by 2-4 years, while temperature has a stronger regional influence.

3.The study warns that apparent carbon gains may mask deeper ecological stresses, raising concerns about forest stability and the risk of large carbon releases.

The Big Picture
Prelims · HighMains · High

An IITM-Pune study projects that carbon stored in India's living forest vegetation will increase by 35% to 97% by 2100, but the gains will be uneven. This is crucial for understanding India's carbon sink capacity and climate resilience, a key topic for Environment and Ecology in UPSC Prelims and Mains.

EVs Account for 10.6% of India's Vehicle Registrations in 2026, Three-Wheelers Lead at 60.5% - FADA Data

India's vehicle registration data for 2026 shows a historic fuel crossover: petrol/diesel share dropped to 83.5% while EVs reached 10.6%. However, the shift is lopsided—two-wheelers and three-wheelers drive EV adoption, while cars prefer CNG/LPG. This data is crucial for understanding India's energy transition and can be tested in Prelims for exact percentages and FADA's role.

Parliamentary Panel Urges Geostationary Satellite for 24x7 Himalayan Forest Fire Monitoring

A parliamentary standing committee has flagged critical gaps in forest fire monitoring in the Himalayas, where 17% of India's landmass accounts for 57% of fire incidents. It recommends launching an Indian geostationary satellite for round-the-clock monitoring, setting up NDRF regional response centres, and formulating a national pine-needle policy. This is crucial for prelims (data, institutions) and mains (environmental governance, disaster management).

Western Himalaya Warming 7.18°C by 2100, Snow Loss Triple Under High Emissions: Study

A new study reveals that the Western Himalaya is warming faster than the central and eastern parts, with winter temperatures projected to rise by over 7°C by 2100 under high emissions. This will lead to severe snow loss, threatening water security for 1.5 billion people dependent on glacier-fed rivers like the Indus, Ganges, and Brahmaputra.
