We are not facing a distant environmental threat. We are living through the sixth mass extinction. It’s not a prediction anymore—it is a present reality, unfolding at an unprecedented pace and scale. Climate change is no longer a topic reserved for academic debates or remote research papers. It has arrived, loud and destructive, disrupting economies, livelihoods, ecosystems, and lives. The question is not whether we can adapt but whether we are even willing to acknowledge what’s happening before us.
The Human and Economic Cost of Climate Change
Climate change is not just about rising temperatures or melting glaciers—it’s about survival, livelihoods, and social stability. Every aspect of life is now under assault, from agriculture to infrastructure, from public health to national defense. In India, where more than half the population is dependent on agriculture, the damage is catastrophic. Crops are increasingly failing due to erratic rainfall, unrelenting heatwaves, and prolonged dry spells. Think of the insect responsible for pollination—will it survive these extremes? If not, what happens to our crops and food systems?
When climate impacts food security, it unleashes a domino effect. With no food, people migrate—this isn’t just “mass migration,” but total displacement. Tens of millions moving due to famine, droughts, and floods. Such movements will strain urban centers, spike unemployment, and unravel the service economy. Who will eat in restaurants, take taxis, or travel to tourist destinations when people are struggling to survive?
Service industries are especially vulnerable. They rely on disposable income, but when the agricultural and manufacturing sectors collapse, so does consumer spending. The economic system is not immune—it is highly interdependent. The idea that the economy can flourish while the environment collapses is a dangerous delusion.
Cities at the Frontline
India’s financial capital, Mumbai, is already experiencing sea level rise. So are Chennai and Kolkata. These aren’t subtle changes; they are existential threats. “Vulnerability” is too soft a term. When sea levels rise, they don’t merely inconvenience a few coastal neighborhoods—they swallow cities. Entire urban centers, home to millions, risk becoming uninhabitable. What happens then?
And it’s not just coastal flooding. Inland cities like Delhi are facing record-breaking heat waves. April 2025 saw temperatures spike 5–8°C above average across North India. Such extremes are not only deadly but also strain energy systems, affect worker productivity, and lead to widespread health crises.
The Public Health Emergency
Climate change is also a public health nightmare. It exacerbates every type of disease—from lifestyle ailments like heart disease and cancer to infectious ones like TB and vector-borne viruses. With increasing temperatures, new viruses—previously dormant in permafrost or ice—are beginning to emerge. These pathogens are ancient, with no known immunity among humans. If COVID-19 brought the global economy to its knees, imagine the havoc that multiple such unknown viruses could create.
This is not science fiction. It’s science fact. Melting glaciers in the Alps have already begun exposing long-lost aircraft wreckage and, with it, the potential for biological surprises buried in ice for decades. This phenomenon is happening in other polar and mountainous regions too. And yet, we continue to live as if this reality is optional.
Denial, Deception, and Dangerous Optimism
Despite overwhelming evidence—from record-breaking wildfires in California and Australia to the 32°C heatwaves in Southeast England—we continue to indulge in climate denial or, worse, blind optimism. Climate deniers often dismiss these events as anomalies. But the frequency and intensity of such anomalies have made them the new normal.
The belief that humanity will simply “adapt” is unfounded. Adaptation requires resources, planning, and, most importantly, time—none of which are abundant. Hoping that human ingenuity will overcome fundamental physical laws is like believing ice won’t melt at 50°C just because you wish it wouldn’t. It’s not belief that will save us—it’s action.
India: The Greatest Risk, the Least Prepared
Tragically, India, one of the countries most at risk from climate impacts, also ranks among the lowest in climate awareness. Our voter priorities rarely reflect environmental concerns, and consequently, our policies don’t either. While the world urges its citizens to “vote green,” environmental consciousness remains peripheral in Indian politics.
We have more to lose than most. Our economy heavily relies on the informal sector, agriculture, and natural resources—all of which are climate-sensitive. Even the manufacturing sector, already small, depends on climate-resilient infrastructure and raw materials. How many of these industries are insulated from heatwaves, water scarcity, or floods?
Meanwhile, our emissions continue to rise. The Paris Agreement aimed to cut emissions to 44% below 2019 levels by 2030. Instead, we are on track to exceed 2019 emission levels. That’s not progress—it’s regression.
A Crisis of Character, Not Just Climate
Climate education isn’t difficult. Even a 10th grader can understand the science. What’s missing is not knowledge but honesty. We are pretending to be asleep because waking up would require uncomfortable choices. Our education system may be producing smart individuals, but not necessarily honest or responsible ones. One can be a climate scientist and still deny climate change—if one lacks the courage to face truth.
This is not pessimism. This is realism. If realism feels pessimistic, it’s only because the truth is terrifying. But acknowledging it is the first step toward change.
The Final Warning
This is the Anthropocene—an era defined by human activity reshaping the Earth. We are the most powerful species to have ever lived, but also possibly the most foolish. More than 75% of wildlife has been wiped out in the last 50 years. The future, if it exists, will look back and wonder: How could they be so blind?
We still have a chance. But only if we act now—individually, politically, economically, and morally. Climate education must be compulsory. Climate action must be urgent. And climate truth must be non-negotiable.
Because the alternative is not just economic stagnation or discomfort.
It is extinction.
