The Centre for Science and Environment (CSE) released a comprehensive report in November 2025 documenting extreme weather events across India throughout the year. The report revealed alarming findings: extreme weather events occurred on 99% of days in 2025, underscoring the deepening climate crisis gripping the country.

Key statistical findings from the report include the loss of 4,064 lives due to various extreme weather events. Agricultural devastation was equally severe, with 9.47 million hectares of crops affected across multiple states. Infrastructure damage was extensive, with 99,533 houses destroyed during the year.

The types of extreme weather events documented span the full spectrum of climate-related disasters. Heat waves and cold waves occurred at unprecedented frequencies, reflecting the widening temperature extremes India now experiences. Floods inundated vast swathes of agricultural and residential land, while lightning strikes claimed hundreds of lives, particularly in rural areas of eastern and central India.

The report highlights that no region of India remained unaffected. From the Himalayan states experiencing cloudbursts and glacial lake outburst floods to peninsular India facing cyclones and unseasonal rainfall, the geographic spread of climate-related disasters has widened dramatically.

CSE researchers attributed this intensification to anthropogenic climate change, citing rising global temperatures, disrupted monsoon patterns, and increased moisture in the atmosphere. The report calls for urgent policy action including early warning systems, climate-resilient agriculture, and greater investment in disaster preparedness infrastructure.

This data is critical context for India's climate negotiations at COP30 in Belém, where India must balance development imperatives with the urgent need to reduce vulnerability to climate extremes that are already costing thousands of lives and billions in agricultural losses annually.
