India's RE Capacity Crosses 200 GW, Solar & Green Hydrogen Lead Clean Energy Transition

India's renewable energy capacity crossed 200 GW (45% of total installed capacity), driven by solar and wind. Key schemes like PM Surya Ghar, PM-KUSUM, National Green Hydrogen Mission, and International Solar Alliance highlight India's climate leadership. This is exam-relevant for prelims data and mains analysis on energy transition, government schemes, and India's climate commitments.

Copernicus C3S: August 2026 Warmest on Record, Breaches 1.5°C Paris Benchmark

August 2026 recorded the highest global-average surface air temperature ever, at 16.96°C, breaching the 1.5°C Paris Agreement benchmark for the first time since November 2025. This data from Copernicus C3S signals accelerating climate change and has direct implications for climate policy, disaster preparedness, and international negotiations.

India's Next Energy Transition: Electrifying Industrial Heat for MSMEs, Manufacturing Competitiveness

India's next energy transition phase targets electrifying industrial heat, especially for MSMEs, to boost manufacturing competitiveness, energy security, and decarbonisation. The article draws a parallel with the solar PV revolution and calls for a coordinated ecosystem of policies, financing, and cluster-level planning to scale the transition.

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.

UK Met Office Forecasts Record El Nino >3°C; 2027 Likely Hottest Year on Record

The UK Met Office has forecast the strongest El Nino in over a century, with Pacific sea surface temperatures rising over 3°C above normal. This unprecedented event could make 2027 the hottest year globally, impacting global weather patterns including drier conditions in India and severe droughts in South America and the West Pacific.

18th BRICS Summit New Delhi Declaration: RSSC Expansion, Space Debris, PAROS Working Group

The 18th BRICS Summit adopted the New Delhi Declaration, underscoring progress in expanding the BRICS Remote Sensing Satellite Constellation (RSSC) to include new space agencies, strengthening space debris mitigation efforts, and advancing discussions on the Prevention of an Arms Race in Outer Space (PAROS) via an open-ended working group. This highlights deepening BRICS cooperation in space technology and security, a key area for UPSC International Relations and Science & Technology segments.
