IMD Forecasts 92% Below-Normal Monsoon Rainfall Amid Rising Extreme Rainfall Events Linked to Climate Change

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 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.

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.

Black Carbon Crisis: 1/3 Himalayan Glacier Loss Linked to 32-42% Brick Kiln Soot Emissions

A new Systemiq report titled 'A Resilient Himalaya' links about one-third of Himalayan glacier mass loss to South Asian black carbon, with brick kilns contributing 32–42% of the deposition. Since black carbon is a short-lived pollutant, reducing kiln emissions can simultaneously improve local air quality and slow glacier melt — a rare fast-win climate action for India.

Monsoon Revival: Rainfall Deficiency Drops to 11.5%, Kharif Sowing Gap Narrows to 2.9%

The monsoon has revived significantly, reducing cumulative rainfall deficiency from 22.8% to 11.5% and narrowing the kharif sowing gap from 20.8% to 2.9%. However, El Niño is strengthening into a 'very strong' event, posing a serious threat to the upcoming rabi season. Proactive supply-side management will be crucial for food security.

1996 India-Bangladesh Ganges Treaty Expiry: Climate Change, Farakka Barrage, and 'Safe Operating Space'

The 1996 India-Bangladesh Ganges Water Treaty is expiring, and the next treaty must address ecological health beyond water allocation. Climate change, Farakka Barrage impacts, and declining river flows threaten biodiversity and livelihoods. The concept of 'Safe Operating Space' (SOS) is proposed for sustainable river management. This is critical for UPSC IR, Environment, and Disaster Management.

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.
