Heatwaves in India

Syllabus: Disaster Management

Source: TH

Context: India witnessed severe heatwaves in March 2025 — 20 days earlier than in 2024 — highlighting the urgent need for short-term and long-term strategies to tackle heat stress and its cascading impacts.

About Heatwaves:

Definition: A heatwave is a prolonged period of excessively hot weather, often accompanied by high humidity, significantly impacting human health, agriculture, and ecosystems.

Key Features: In India, a heatwave is declared when maximum temperature exceeds 40°C in plains and 30°C in hilly areas. It is intensified by factors like humidity, wind speed, and urban heat islands. Global warming and climate change are major contributors to the increased frequency and intensity.

• In India, a heatwave is declared when maximum temperature exceeds 40°C in plains and 30°C in hilly areas.

• It is intensified by factors like humidity, wind speed, and urban heat islands.

• Global warming and climate change are major contributors to the increased frequency and intensity.

Impacts of Heatwaves:

Health Impacts: Causes heat stress, affecting kidneys, liver, brain, and can lead to death. Vulnerable groups: elderly, women, outdoor workers, poor communities.

• Causes heat stress, affecting kidneys, liver, brain, and can lead to death.

• Vulnerable groups: elderly, women, outdoor workers, poor communities.

Economic and Livelihood Impacts: Reduces agricultural productivity, kills livestock. Lowers work hours, especially among informal sector workers. Estimated loss: 3%–5% of GDP; in 2023, 6% of India’s work hours were lost due to heat stress.

• Reduces agricultural productivity, kills livestock.

• Lowers work hours, especially among informal sector workers.

• Estimated loss: 3%–5% of GDP; in 2023, 6% of India’s work hours were lost due to heat stress.

Social Inequity: Disproportionately affects marginalized sections, migrants, women, and the elderly.

• Disproportionately affects marginalized sections, migrants, women, and the elderly.

Challenges associated Heatwave are:

Inadequate Implementation: Heat Action Plans (HAPs) exist but face poor execution.

Lack of Comprehensive Data: Incomplete heat-related morbidity and mortality statistics.

Urban Vulnerabilities: Confined spaces, dense housing amplify risks in poor neighbourhoods.

Infrastructure Gaps: Insufficient cooling shelters, public water points, and ORS availability.

Limited Awareness: Public education on heat safety remains patchy.

Way Ahead:

Short-Term Measures: Strengthen HAPs: Update State and city-level plans factoring in humidity and local vulnerabilities. Early Warning Systems: Adopt Heat Health Alert (HHA) systems using both day and night temperatures. Immediate Public Health Actions: Ensure availability of drinking water, ORS, staggered work hours. Targeted Advisories: Provide localized and socially contextual heat advisories.

Europe is Warming Faster

Syllabus: Environment

Source: IE

Context: The 2024 European State of the Climate Report revealed that Europe is warming about twice as fast as the global average, intensifying extreme weather events across the continent.

What is Europe Warming?

• Europe’s average annual temperature has risen by 2.4°C above pre-industrial levels, compared to the global average of 1.3°C.

• This accelerated warming has led to unprecedented heatwaves, floods, and shorter cold periods across the continent.

Reasons Behind Europe’s Faster Warming:

Arctic Proximity: A significant part of Europe lies close to the Arctic, which is warming 3–4 times faster than the global average due to ice melt and reduced albedo.

Reduction in Aerosols: Cleaner air in Europe due to reduced aerosol emissions decreases sunlight reflection, allowing more solar energy absorption and higher temperatures.

Changes in Atmospheric Circulation: Increased frequency of summer heatwaves due to shifts in atmospheric patterns.

Higher Sea Surface Temperatures: Warming oceans around Europe add to the atmospheric temperature rise.

Urban Heat Island Effect: Expanding urban areas trap more heat, worsening local temperature extremes.

Melting of Glaciers: Similar to Arctic ice loss, glacier melting enhances heat absorption.

Consequences of Europe’s Accelerated Warming:

Severe Heatwaves: Longer and more intense, impacting human health, agriculture, and biodiversity.

Increased Flooding and Rainfall Variability: Higher temperatures lead to heavier precipitation events and flooding.

Economic Strain: Damage to infrastructure, agriculture, and tourism sectors.

Reduced Cold Days: Fewer freezing days, impacting ecosystems reliant on cold conditions.

Biodiversity Threats: Altered habitats and species migration patterns across Europe.

Way Ahead:

Strengthen Climate Action: Accelerate EU Green Deal targets and promote carbon neutrality initiatives.

Adapt Urban Planning: Expand green spaces, cool roofs, and sustainable infrastructure to counter urban heat islands.

Enhance Early Warning Systems: Improve forecasting and disaster preparedness for heatwaves and floods.

Promote Renewable Energy: Reduce dependence on fossil fuels and invest in solar, wind, and hydropower.

Strengthen International Cooperation: Collaborate globally to limit warming below 1.5°C, as set under the Paris Agreement.

Conclusion:

Europe’s alarming rate of warming demands urgent, bold, and collaborative action on both mitigation and adaptation fronts. A proactive, sustainable strategy is critical to safeguard the continent’s ecosystems, economies, and communities.
