Kolkata, June 19, 2026: A new report by Azim Premji University has sounded a stark warning about the rapidly escalating climate crisis along India’s 11,000-km coastline, revealing that major environmental changes are expected within the next 14 years.
Titled “Indian Coastal Region: Climate Projections 2021-2040”, the study uses high-resolution district-level data to map climate shifts across coastal India, highlighting rising temperatures, dangerous heat stress, intensified monsoons, sea-level rise, and growing cyclone risks.
Key Highlights
Temperatures Rising Fast
- India’s average temperature is projected to increase by 1.5°C.
- Around 40 coastal districts may witness summer temperatures rise by more than 1°C.
Dangerous Heat Conditions Ahead
- Coastal regions of Kerala and Tamil Nadu are expected to experience wet-bulb temperatures nearing 31°C, levels considered highly dangerous for human health.
- Ernakulam is projected to record the highest increase in summer temperatures at +1.3°C.
Stronger Monsoons on the West Coast
- Coastal Maharashtra and Gujarat are likely to receive significantly higher rainfall.
- Surat could witness a 23% increase in Southwest Monsoon rainfall.
- Suburban Mumbai may experience nearly an additional week of heavy rainfall annually.
Sea-Level Rise and Coastal Erosion
- Global sea levels could rise by 15 cm by 2050, accelerating coastal erosion.
- Parts of Odisha’s Ganjam district face the risk of becoming “ghost villages” due to land loss and displacement.
Cyclone Threat Intensifying
- Rising sea-surface temperatures, increasing at 0.27°C per decade, are expected to fuel more powerful tropical cyclones.
West Bengal Under Pressure
The report identifies South 24 Parganas and Purba Medinipur among the vulnerable districts, with summer temperatures projected to rise by 1°C. Northeast monsoon rainfall in Purba Medinipur could increase by up to 11%, adding pressure on already fragile coastal ecosystems.
In the Sundarbans, repeated embankment breaches are worsening groundwater salinity, affecting agriculture, public health, and livelihoods. Women-led mangrove restoration initiatives are emerging as a crucial defense against coastal erosion and climate impacts.
Experts Warn of a Narrow Window for Action
“Climate change is not a distant future challenge—it is today’s reality,” said Anurag Behar, CEO of Azim Premji Foundation, stressing the urgent need to redesign infrastructure and governance systems for climate resilience.
Harini Nagendra, Director of the School of Climate Change and Sustainability at Azim Premji University, said the findings demonstrate that climate change is now a “hyper-local and immediate” challenge, requiring a shift from reactive mitigation to proactive adaptation.
Bottom Line
The report delivers a clear message: India’s coastal communities are already experiencing the early impacts of climate change, and the next decade will be critical for building resilience, protecting livelihoods, and safeguarding ecosystems from escalating climate risks.
