IMD Issues Orange Alert for Heavy Rain; Western Disturbances Explained for Rabi Crops & Climate

NOAA Projects 69% Chance of Historic El Niño Since 1950; IMD Reports Below-Normal Monsoon

A potentially historic El Niño is developing in the Pacific, with NOAA projecting a 69% chance it will exceed the strongest events since 1950. For India, the impact may lag by 40-45 days, likely after the southwest monsoon's official withdrawal, though the current monsoon is already 12% below normal.

WMO Warns 'Very Strong' El Nino Till Feb 2027; Threat to Monsoon & Winters

The World Meteorological Organization (WMO) warns of a 'very strong' El Nino that will persist until February 2027, with potential to disrupt global weather patterns, including India's monsoon and winter. This is a critical update for exam aspirants as it links to geography, climate, and agriculture.

Climate Impact Lab Report Projects 15,800 Additional Heat Deaths in India Due to Super El Nino

The Climate Impact Lab projects 15,800 additional heat-related deaths in India between Sept 2026 and Feb 2027 due to the ongoing 'Super El Niño'. Globally, 451,000 excess deaths are expected in the first six months. The report warns that this El Niño is a 'postcard from the future', bringing temperatures typical of 20 years from now without adaptation.

Western Ghats ESA: Gadgil and Kasturirangan Reports, 5 Draft Notifications, State Opposition

The Western Ghats Ecologically Sensitive Area (ESA) notification has been in limbo since 2010, with two major committee reports (Gadgil and Kasturirangan) offering contrasting approaches. With five draft notifications issued between 2014 and 2026 and states like Karnataka opposing the move, this issue is a classic UPSC case study on balancing conservation with livelihoods, federalism, and scientific decision-making.

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.

Climate Change Study: 0.01°C/yr Temp Rise, 3.97mm/yr Rain Decline in Nilgiri Biosphere Reserve

A study reveals that climate change is disrupting the phenology of forests in the Nilgiri Biosphere Reserve, with a 0.01°C annual temperature rise and 3.97 mm annual rainfall decline from 1950 to 2018, leading to altered growing seasons and threatening endemic species. This data is critical for understanding climate impacts on biodiversity hotspots, a recurring theme in UPSC environment and geography questions.

Myristica Swamps in Western Ghats: 500-Million-Year-Old Ecosystem at Risk, Only 53 Patches Remain

Myristica swamps, ancient freshwater wetlands in the Western Ghats with 500 million years of genetic history, are down to just 53 patches in Kerala. They are vital for flood control, groundwater recharge, and biodiversity but face extinction from agriculture, logging, and past plywood exploitation. Urgent conservation is needed.

Nepal Demands Climate Compensation from US, China, India After Glacial Flood Kills 1,200

Nepal, emitting only 0.1% of global GHGs, is demanding direct compensation from the top three emitters (US, China, India) after a glacial collapse killed 1,200+ people. This shifts the climate debate from charity to legal liability, testing the limits of adaptation and the principle of climate justice.
