India to witness 43% rise in extreme rainfall by 2030, 2.5-fold surge in heatwave days: Study

  
By Rajiv Shah 
A groundbreaking study released by IPE Global and Esri India has warned that India is on course to experience a 43% increase in the intensity of extreme rainfall events and a 2.5-fold rise in heatwave days by 2030. Titled "Weathering the Storm", the study paints a stark picture of the country becoming simultaneously hotter and wetter due to the accelerating impacts of climate change.
The research, launched at the International Global-South Climate Risk Symposium in New Delhi, reveals that metropolitan cities including Mumbai, Chennai, Delhi, Surat, Thane, Hyderabad, Patna and Bhubaneswar will see a twofold increase in heatwave days. Extended heat conditions are expected to drive more frequent and erratic rainfall events, with eight out of ten Indian districts likely to face such extremes by the end of the decade.
Data from the study indicates that between 1993 and 2024, India witnessed a 15-fold increase in extreme heatwave days during the March-to-September period, with a 19-fold increase recorded in the past decade alone. The monsoon season, too, has shown signs of transformation, marked by prolonged summer-like conditions and greater unpredictability in rainfall.
Lead author Abinash Mohanty, Head of Climate Change and Sustainability at IPE Global, stressed that climate extremes are set to intensify further with tier-I and tier-II cities bearing the brunt. "Around 72% of these urban centres are likely to face increased heat stress and rainfall extremes, accompanied by storm surges, lightning, and hailstorms. We must adopt hyper-granular risk assessments and establish climate-risk observatories to safeguard our agriculture, industry, and infrastructure,” he said.
The study identifies Gujarat, Rajasthan, Tamil Nadu, Odisha, Uttarakhand, Himachal Pradesh, Maharashtra, Uttar Pradesh, Meghalaya, and Manipur as particularly vulnerable, with over 80% of districts in these states projected to suffer from both heat stress and extreme rainfall events. Coastal districts are also at high risk, with 69% likely to experience extended summer discomfort by 2030, a figure expected to rise to 79% by 2040.
Ashwajit Singh, Founder and Managing Director of IPE Global, noted that the findings echo the recent global warnings on extreme heat. “Nearly all countries of the Global South, including India, must now grapple with improving living standards while urgently addressing climate threats. This study is a clarion call to act—leveraging innovation and preparedness to turn risk into resilience.”
The study also found a clear linkage between areas experiencing frequent heatwaves and those witnessing incessant rainfall, especially in the JJAS season. Many of these districts are undergoing a 63% change in land use and land cover, driven by microclimatic disruptions such as deforestation, mangrove loss, and wetland encroachment.
Agendra Kumar, Managing Director of Esri India, highlighted the critical role of geospatial tools in addressing climate challenges. “The intensifying climate extremes are no longer anomalies—they are now patterns. Geographic Information System (GIS) technology enables data-driven planning, infrastructure resilience, and public preparedness. We are committed to helping India and its institutions build a sustainable, climate-adaptive future.”
The study proposes several strategic interventions, including the establishment of a Climate Risk Observatory (CRO) for real-time monitoring and forecasting of chronic and acute heat and rainfall risks. It also recommends the development of risk-financing instruments and the appointment of heat-risk champions within district disaster management authorities to localize and accelerate mitigation efforts.
Offering a first-of-its-kind district-level assessment of heat and rainfall extremes in India, the study argues for more localized climate risk modeling. Global models alone, it says, are insufficient to address the complex and non-linear dynamics of climate change on the ground.
Using a dynamic ensemble of climate models and spatial analyses, the research presents projected scenarios for 2030 and 2040, offering empirical evidence of exposure to extreme events across India. It underscores that identifying, monitoring, and managing climate risks at a hyper-local level is not just a scientific imperative, but a developmental one.

Was Netaji forced to alter face, die in obscurity in USSR in 1975? Was he so meek?

  By Rajiv Shah   This should sound almost hilarious. Not only did Subhas Chandra Bose not die in a plane crash in Taipei, nor was he the mysterious Gumnami Baba who reportedly passed away on 16 September 1985 in Ayodhya, but we are now told that he actually died in 1975—date unknown—“in oblivion” somewhere in the former Soviet Union. Which city? Moscow? No one seems to know.

Love letters in a lifelong war: Babusha Kohli’s resistance in verse

By Ravi Ranjan*  “War does not determine who is right—only who is left.” Bertrand Russell’s words echo hauntingly in our times, and few contemporary Hindi poets embody this truth as profoundly as Babusha Kohli. Emerging from Jabalpur, Madhya Pradesh, Kohli has carved a unique space in literature by weaving together tenderness, protest, and philosophy across poetry, prose, and cinema. Her work is not merely artistic expression—it is resistance, refuge, and a call for peace.

Swami Vivekananda's views on caste and sexuality were 'painfully' regressive

Asbestos contamination in children’s products highlights global oversight gaps

By A Representative   A commentary published by the International Ban Asbestos Secretariat (IBAS) has drawn attention to the challenges governments face in responding effectively to global public-health risks. In an article written by Laurie Kazan-Allen and published on March 5, 2026, the author examines how the discovery of asbestos contamination in children’s play products has raised questions about regulatory oversight and international product safety. The article opens by reflecting on lessons from the COVID-19 pandemic, noting that governments in several countries were slow to respond to early warning signs of the crisis. Referring to the experience of the United Kingdom, the author writes that delays in implementing protective measures contributed to “232,112 recorded deaths and over a million people suffering from long Covid.” The commentary uses this example to illustrate what it describes as the dangers of underestimating emerging threats. Attention then turns...

Echoes of Vietnam and Chile: The devastating cost of the I-A Axis in Iran

​ By Ram Puniyani  ​The recent joint military actions by Israel and the United States against Iran have been devastating. Like all wars, this conflict is brutal to its core, leaving a trail of human suffering in its wake. The stated pretext for this aggression—the brutality of the Ayatollah Khamenei regime and its nuclear ambitions—clashes sharply with the reality of the diplomatic landscape. Iran had expressed a willingness to remain at the negotiating table, signaling a readiness to concede points emerging from dialogue.

The kitchen as prison: A feminist elegy for domestic slavery

By Garima Srivastava* Kumar Ambuj stands as one of the most incisive voices in contemporary Hindi poetry. His work, stripped of ornamentation, speaks directly to the lived realities of India’s marginalized—women, the rural poor, and those crushed under invisible forms of violence. His celebrated poem “Women Who Cook” (Khānā Banātī Striyāṃ) is not merely about food preparation; it is a searing indictment of patriarchal domestic structures that reduce women’s existence to endless, unpaid labour.

Authoritarian destruction of the public sphere in Ecuador: Trumpism in action?

By Pilar Troya Fernández  The situation in Ecuador under Daniel Noboa's government is one of authoritarianism advancing on several fronts simultaneously to consolidate neoliberalism and total submission to the US international agenda. These are not isolated measures, but rather a coordinated strategy that combines job insecurity, the dismantling of the welfare state, unrestricted access to mining, the continuation of oil exploitation without environmental considerations, the centralization of power through the financial suffocation of local governments, and the systematic criminalization of all forms of opposition and popular organization.

The price of silence: Why Modi won’t follow Shastri, appeal for sacrifice

By Arundhati Dhuru, Sandeep Pandey*  ​In 1965, as India grappled with war and a crippling food crisis, Prime Minister Lal Bahadur Shastri faced a United States that used wheat shipments under the PL-480 agreement as a lever to dictate Indian foreign policy. Shastri’s response remains legendary: he appealed to the nation to skip one meal a day. Millions of middle-class households complied, choosing temporary hunger over the sacrifice of national dignity. Today, India faces a modern equivalent in the energy sector, yet the leadership’s response stands in stark contrast to that era of self-reliance.
