The unequal cost of survival: Climate change’s burden falls heaviest on the poor

By Vikas Meshram 

Climate change has emerged as one of the greatest challenges of our time, profoundly affecting the global economy, ecosystems, and human life. Yet the burden of this planetary emergency is not shared equally. The crisis is more than environmental; it is social, economic, and moral. Its harshest consequences fall on those who contributed the least—poor and developing nations.

Across the world, the frequency and intensity of natural disasters are rising. But these disasters do not strike all countries or communities with equal force. Socially and economically vulnerable populations suffer the most, while wealthy nations—historically responsible for the bulk of greenhouse gas emissions—possess the technological and financial resources to cope and recover. This inequity makes the call for climate justice urgent and unavoidable. Those most affected must be placed at the centre of policy, negotiation, and investment.

Fueled by unchecked industrialization and profit-driven models of development, greenhouse gas emissions have escalated, pushing Earth’s average temperature to dangerous levels. As a result, extreme weather, rising seas, melting glaciers, and ecosystem collapse are becoming daily realities. Climate justice demands that responsibility for mitigation and adaptation be shared fairly and that communities on the frontlines are protected. Countries like Bangladesh and the Maldives face the imminent threat of drowning seas, while many African nations confront worsening drought, hunger, and displacement.

International efforts such as the Green Climate Fund and negotiations under the United Nations framework seek to support adaptation and mitigation. But the gap between promise and practice remains wide. Every individual has the right to live in a healthy and safe environment. Without immediate and effective action, future generations will inherit a world defined by extreme weather, resource scarcity, and irreversible ecological loss.

India illustrates both the severity of the threat and the urgency of action. In the financial year 2023 alone, more than 2,100 people died from extreme weather events— the highest recorded since 2014. In 2022, ten major climate-related disasters cost the country nearly USD 87 billion. The World Risk Report 2024 ranks India third among 193 countries in disaster risk exposure. Human rights—from access to water and food to health and survival—are increasingly endangered. In response, India has launched initiatives such as the National Solar Mission and the Green India Mission, expanding renewable energy, afforestation, and sustainable farming as models of resilience.

But domestic efforts are not enough. True climate justice requires a global partnership. Public awareness, international collaboration, technology-sharing, and finance must flow toward vulnerable countries and communities. The principle of “common but differentiated responsibilities” remains unfulfilled. Developed countries that have grown rich by burning fossil fuels must support those now bearing the consequences.

The crisis is also reaching beyond Earth. Scientists warn that global warming is disrupting even the orbital space surrounding the planet. Warming near the surface and cooling in the upper atmosphere are reducing atmospheric drag, slowing the decay of space debris and shrinking safe orbital zones. Research from MIT and data from The Aerospace Corporation suggest that without swift emission reductions, low-Earth orbit could lose up to 82 percent of usable space by the end of the century. The growing accumulation of debris threatens satellites essential for communication, weather forecasting, and navigation—proof that climate change now jeopardizes not only life on Earth but our technological future.

Climate change is already transforming food systems, water supplies, public health, biodiversity, and human settlement. Over the past seven decades, climate-related disasters have increased eightfold. Scientists understood the danger more than a century ago, warned governments in the 1970s, and issued unmistakable alerts in the late 1980s. Yet global emissions continue to rise, and 2024 stands as the hottest year on record. The window for incremental progress has closed. What is needed now is immediate, collective, and ethical action—grounded in equity and human dignity.

If the world fails to limit emissions and protect vulnerable societies, climate change will not merely reshape the environment; it will redefine human existence itself.
