The startling increase in extreme weather deaths in India has exposed a hazardous new climate reality. Up to 4,064 deaths were recorded in just the first nine months of 2025, according to the Climate India 2025 report by the Centre for Science and Environment (CSE). This represents a startling 48% increase from four years prior. The increasing vulnerability of India’s population and agricultural systems is highlighted by these deaths, which are brought on by heatwaves, cold spells, storms, severe rainfall, floods, and landslides. India is experiencing a period marked by climate instability, record-breaking temperatures, and unprecedented destruction, with at least one extreme weather event occurring on 99% of days between January and September.

What is Driving the Sharp Rise in Extreme Weather-Related Deaths?

The dramatic rise in extreme weather deaths in India is linked to several climate and environmental factors that have intensified in recent years. Disasters are becoming more common and severe due to a combination of changing monsoon behavior, rising air temperatures, and shifting rainfall patterns.

Key reasons behind the increase:

• Monsoon volatility: In India, the monsoon season remains the most deadly; in 2025 alone, 3,007 of 4,064 fatalities occurred during the monsoon.
• Record-breaking temperature extremes: September had one of the highest mean temperatures ever recorded, while February 2025 was the warmest month in 124 years.
• Persistent climate extremes: 18 states and UTs reported more extreme weather days than they had in 2022.
• Geographical spread: The extent of exposure was evident in the eight months of nonstop harsh weather that affected at least 30 states and UTs.
• Underlying warming trend: Extreme heat, heavy rains, storms, and landslides are becoming more frequent and intense due to rising CO₂ emissions.

The intensity of the effects can no longer be viewed as isolated catastrophes, as they are now part of a broader climate pattern directly related to global warming.

Which Regions and Sectors Have Suffered the Most Damage?

According to the analysis, there is an unequal distribution of extreme weather deaths in India, with some states facing a disproportionate burden. The effects go well beyond human mortality; infrastructure, livelihoods, and agriculture have all suffered significant losses.

Worst-hit regions and sectors:

• Out of all the states, Madhya Pradesh had the most fatalities.
• With 8.4 million hectares of agricultural land devastated, Maharashtra had the greatest impact.
• Crop loss in agriculture as a whole increased fourfold from 2022.
• With 2,440 fatalities, heavy rain, floods, and landslides were the deadliest incidents, followed by lightning and storms.
• Data gaps persist, especially in agriculturally vital areas such as West Bengal and Andhra Pradesh, suggesting that actual losses may be substantially higher.

India’s agricultural industry has become a hotspot of climate-related vulnerability, particularly in rain-fed areas.

How Does 2025 Compare to Earlier Years, and What Climate Records Were Broken?

A critical reason extreme weather deaths in India rose so sharply is that 2025 set multiple climate records, creating conditions that enabled widespread destruction.

Climate records for 2025:

• The seventh driest month since 1901 was January.
• In 124 years, February was the warmest month.
• One of the warmest overnight temperatures ever recorded occurred in September.
• From January through September, 99% of the days had extreme weather.
• Since monitoring began in 2022, Himachal Pradesh has experienced the most extreme weather events in 2025.

Sunita Narain, director general of CSE, claims that, as adaptation is insufficient to address catastrophes of this scale, India must now focus on mitigation.

What Types of Events Are Causing Most of the Deaths?

Understanding the distribution of extreme weather impacts helps explain why extreme weather deaths in India continue to rise.

The dominance of rainfall-related disasters shows the shifting nature of India’s climate: more moisture, more intense storms, and more unpredictable monsoon cycles.

What Needs to Happen Now?

The sharp increase in extreme weather deaths in India underscores the necessity of a two-pronged strategy: rigorous adaptation to safeguard vulnerable populations and extensive mitigation to slow down global warming.

Priority actions:

• Boost early warning systems for heatwaves, storms, floods, and lightning.
• Climate-proof agriculture using insurance, water-efficient techniques, and adaptable crop varieties.
• Urban planning changes to lower the risk of flooding in growing cities.
• Invest in local climate adaptation, particularly in rural and tribal areas.
• CSE has called for international cooperation to cut CO₂ emissions because adaptation on its own is no longer enough.

India needs to prepare for a future when extreme weather will be the norm rather than the exception.

Frequently Asked Questions (FAQs)

Q1. Why are extreme weather deaths increasing so rapidly?

Because of increased monsoon rainfall, temperature extremes, and atmospheric instability driven by climate change, storms, landslides, and lightning are occurring on a scale never before seen.

Q2. Which extreme weather events are the most dangerous in India?

The most significant causes of fatalities are landslides, floods, and heavy rains, followed by lightning and storms. Although they cause fewer fatalities, vulnerable people are disproportionately affected by heatwaves.

Q3. Can India reduce the impacts of extreme weather in the future?

Yes. India can drastically lower future losses with improved disaster preparedness, early warning systems, climate-resilient agriculture, and national and international carbon reductions.
