“Climate change is a major threat to the existence of many developing countries.” (Narendra Modi)
Muzamil Arif
Climate change stands as the defining existential challenge of the 21st century a crisis forged by human activity that now threatens the very foundations of civilization, biodiversity, and planetary stability. Once dismissed as a distant scientific warning, it has become an immediate and harsh reality marked by record-shattering temperatures, devastating extreme weather events, and cascading ecological disruptions. As of August 2026, the world has already crossed critical thresholds. The past eleven years (2015–2025) rank among the warmest on record, with global mean temperatures hovering around 1.42–1.44°C above pre-industrial levels. This relentless warming, driven primarily by greenhouse gas emissions, demands urgent and collective global action. For a country like India, with its diverse geography, massive population, and developing economy, the stakes are extraordinarily high.
SCIENTIFIC BASIS AND GLOBAL CURRENT SCENARIO
The scientific consensus remains unequivocal: human activities — primarily the burning of fossil fuels, deforestation, intensive agriculture, and industrial processes — have unequivocally caused the observed warming. Atmospheric concentrations of carbon dioxide, methane, and nitrous oxide continue to rise, pushing Earth’s energy imbalance to historic highs. Ocean heat content reached new records in 2025, while sea levels continue their steady rise. Glaciers are retreating rapidly, and Antarctic sea ice remains at alarmingly low levels.
Recent reports, including the “10 New Insights in Climate Science 2025/2026,” highlight accelerating groundwater depletion, declining land carbon uptake, and signs that warming may be accelerating. Extreme weather events — heatwaves, floods, droughts, wildfires, and intensified cyclones — have become more frequent and severe. In 2025 alone, such events caused trillions of dollars in economic losses and claimed thousands of lives worldwide. Ocean acidification and marine heatwaves have triggered widespread coral bleaching, threatening entire ecosystems. Biodiversity loss is accelerating at rates far exceeding natural baselines, while food systems face mounting stress from shifting rainfall patterns and extreme heat.
IMPACTS ON INDIA.
India confronts these challenges with acute vulnerability. As a tropical nation with a 7,500 km coastline, the fragile Himalayan ecosystem, and over 1.4 billion people, it ranks among the most climate-vulnerable countries. In 2025, extreme weather events affected the country on more than 330 days, resulting in significant loss of life and massive economic damage. Prolonged heatwaves, with temperatures frequently crossing 40–45°C, have disrupted agriculture, reduced labour productivity, and strained public health infrastructure. February 2025 was recorded as India’s hottest in 125 years.
Erratic monsoon patterns have led to devastating floods in urban centres like Mumbai, Kolkata, and Chennai, while other regions face prolonged droughts. Rising sea levels threaten coastal communities and low-lying islands. Himalayan glaciers are melting at an accelerated pace, endangering the water security of hundreds of millions who depend on the Ganges, Indus, and Brahmaputra river systems. Agriculture, which employs nearly half of India’s workforce, faces compound risks including new pests, soil degradation, and yield losses. Vector-borne diseases are spreading to new areas, and urban air pollution often compounds climate-induced health risks. Economically, climate change is estimated to erode 4–6% of India’s GDP annually through lost productivity, infrastructure damage, and higher adaptation costs.
INTERNATIONAL EFFORTS AND PERSISTENT CHALLENGES
Globally, the Paris Agreement continues to serve as the central framework, yet collective progress remains insufficient. At COP30 held in Belém, Brazil in 2025, countries submitted updated Nationally Determined Contributions (NDCs), but current policies still project warming of 2.3–2.8°C by 2100 — well above the 1.5°C safe limit. The emissions gap remains wide, and the remaining global carbon budget is being exhausted rapidly.
Key challenges include slow fossil fuel phase-out, inadequate climate finance for developing nations, and geopolitical tensions that hinder cooperation. While renewable energy deployment has seen remarkable growth worldwide, with costs falling dramatically, hard-to-abate sectors and political resistance continue to slow the transition. Equity remains a core issue: nations least responsible for historical emissions suffer the most severe consequences. Technological solutions such as carbon capture, green hydrogen, and advanced energy storage are progressing but scaling too slowly to match the urgency of the crisis.
INDIA’S RESPONSE AND INITIATIVES
Despite these challenges, India has demonstrated both ambition and pragmatism. The country achieved its target of 50% non-fossil fuel installed power capacity five years ahead of the 2030 deadline set under the Paris Agreement. By early 2026, renewable energy capacity surpassed 270 GW, with solar and wind leading the surge. India now ranks among the world’s fastest-growing renewable energy markets and remains firmly committed to reaching 500 GW of non-fossil capacity by 2030 and net-zero emissions by 2070.
Flagship initiatives such as the National Solar Mission, International Solar Alliance, National Green Hydrogen Mission, and LiFE (Lifestyle for Environment) movement reflect India’s proactive stance. The country is also advancing its carbon credit trading scheme and investing heavily in electric mobility, grid modernization, and climate-resilient infrastructure. Community-led adaptation programmes, agroforestry, watershed management, and promotion of climate-smart agriculture are yielding encouraging results at the grassroots level. India’s approach seeks to balance rapid economic development and energy access for all with responsible climate action — a model that could inspire the Global South.
THE WAY FORWARD: SOLUTIONS AND HOPE
Addressing climate change requires a comprehensive, multi-pronged strategy. Mitigation demands deep and rapid decarbonisation: phasing down fossil fuels, scaling renewable energy with robust storage solutions, enhancing energy efficiency, and preserving forests through nature-based solutions. Adaptation measures — including early warning systems, climate-resilient crops, sustainable urban planning, and protective infrastructure — are equally vital.
International climate finance, technology transfer, and capacity building must flow adequately to developing countries. Behavioural change, circular economy models, and youth-driven climate action will play decisive roles. For India, priorities include peaking emissions at the earliest, electrifying transport, decarbonising hard-to-abate sectors, and building resilience in agriculture and coastal zones.
CONCLUSION
Climate change is not merely an environmental issue; it is a civilizational challenge encompassing justice, security, equity, and long-term survival. The choices made in this decisive decade will determine the fate of generations to come. While the situation is grave and temporary exceedance of the 1.5°C threshold appears likely, hope lies in human ingenuity, falling costs of clean technologies, growing public awareness, and demonstrated policy momentum.
India has the opportunity to pioneer a model of inclusive, sustainable, and green growth that balances development with planetary health. The time for incremental half-measures has passed. This generation must rise to the challenge with determination, solidarity, and transformative action. Only through collective wisdom and urgent execution can we ensure that future generations inherit a habitable, thriving, and equitable Earth.
