Murky pattern of temperature keeps confusion alive
The ENSO (El Niño-Southern Oscillation) cycle plays a crucial role in shaping global weather patterns, particularly the Indian monsoon. However, recent anomalies in sea surface temperatures (SST) and wind patterns in the Pacific Ocean have created uncertainty regarding whether 2025-26 will be an El Niño or La Niña year. This ambiguity raises concerns about the reliability of monsoon forecasts, which are critical for […]

How does La Niña affect India’s climate
Context: La Niña is significantly influences global weather, particularly in India, where it impacts the monsoon and winter seasons. Relevance: GS 1 (Geography ) , GS 3 (Climate Change) La Niña is a climate phenomenon that occurs when the ocean surface temperatures in the central and east-central equatorial Pacific cool periodically. The term “La Niña” is Spanish for “little […]
Global and Local Implications of Landscape Fire Pollution
Context: According to a study published in The Lancet journal, over 90 per cent of the global deaths per year linked to air pollution from landscape fires were in low and middle-income countries, including India. The study covers all kinds of fires in any natural of cultural landscapes like fires in forests, grasslands, vegetated areas […]
NASA Data Shows Significant Decline in Earth’s Freshwater Levels
Context: Recent observations from NASA and the German Aerospace Center’s GRACE (Gravity Recovery and Climate Experiment) satellites indicate a concerning trend: a significant decline in Earth’s total freshwater levels since 2014. This decline points to pressing global water security issues, highlighting the impacts of climate change and increased water usage on freshwater resources. Relevance: GS […]
