The True Price of a Melting Planet: Counting the Economic Cost of Climate Change

As we navigate through this decade, climate change is no longer a distant threat confined to the future - it is here and now, unraveling our economies and upending the way we live. Images of raging wildfires, devastating floods, and relentless hurricanes have become all too familiar. Then why aren't we acting?

Many leaders argue that aggressive climate policies can hurt industries like coal, oil, and manufacturing, leading to job losses and economic challenges. But is it true? Is it practical?

Behind every dramatic image of nature’s wrath lies an economic story - one of mounting costs that ripple through industries, governments, and societies. The reality is stark: climate change is not just an environmental problem. It is a financial catastrophe in the making, and the price tag is climbing faster than we might realise.

But the real issue runs deeper - until the environment is treated as an integral part of finance, we will continue to follow the historical blunder of a capitalist development model.

A model, where coal, and many other critical resources, have no ecosystem value associated with them. This disconnect perpetuates a system where environmental destruction remains external to economic considerations, perpetuating unsustainable growth.

It’s more than just the damage to infrastructure or the price of rebuilding communities. A report from the World Economic Forum indicates that since the year 2000, the world is paying $16 million per hour for climate-related damage. That works out at $143 billion every year, since then.

This data was released by the scientists at Victoria University of Wellington in New Zealand. They also analysed 185 extreme weather events from 2000 to 2019 using an approach called 'extreme event attribution. As per the WEF, the global cost of climate change damage is estimated to be between $1.7 trillion and $3.1 trillion per year by 2050.

The true cost of this is buried in the long-term disruptions that impact everything from food production to healthcare to the insurance premiums we pay.

Counting the Cost: Direct and Indirect Economic Impacts

At first glance, calculating the economic cost of climate change seems straightforward—simply add up the damages from extreme weather events like hurricanes, floods, and wildfires. For instance, as per the reports by National Weather Service, the aftermath of Hurricane Katrina in 2005, considered as the costliest hurricane to ever hit the United States, resulted in over 1,833 fatalities and nearly $108 billion in damages in the country. The recent Hurricane Helena is also estimated to cost nearly $35 billion. 

Yet, how do we account for the increased vulnerability of communities and ecosystems around these events? The economic cost alone fails to capture the long-term impacts on people's lives and the fragile ecosystems that support them. While it's tempting to focus on financial losses, can we truly measure the cost of lost livelihoods, displaced communities, and broken ecosystems? This is a question we must ask ourselves as we face an uncertain future - how do we quanitify what cannot easily be measured?

Extreme weather events, such as prolonged droughts and erratic rainfall patterns, directly impact crop yields, forcing governments, like the Indian government, to pay compensation to farmers for destroyed crops. This has a cascading effect on economies dependent on agriculture, impacting rural livelihoods and increasing the burden on state finances.

Indirect costs, on the other hand, are harder to quantify but equally disruptive. Disruptions in transportation and supply chains, due to climate-related damages to infrastructure, can hinder production and trade. Extreme weather events like heatwaves also cause power disruptions, which in turn affect the manufacturing sector, leading to production delays and increased costs.

How Climate Change is Reshaping the Global GDP

According to a study by the Swiss Re Institute, the global GDP could shrink by 18% over the next 30 years if no action is taken to mitigate climate change. This decline is driven not only by the physical damage to infrastructure but also by shifts in productivity, resource availability, and human health. Countries in the global south, which often lack the resources to adapt to these changes, are projected to suffer the most. In sub-Saharan Africa and South Asia, the economic impact could reduce GDP by up to 25%, plunging millions further into poverty.

One key driver of this economic decline is the loss of labour productivity. As temperatures soar, outdoor workers in sectors such as agriculture and construction are forced to reduce their working hours, leading to lower productivity and higher costs for businesses. It’s estimated that by 2030, extreme heat could result in over $2 trillion in lost productivity worldwide, a number that will only increase as global temperatures continue to rise.

Over time, rising sea levels and frequent storm surges could submerge coastal cities, leading to a significant reduction in real estate values and tourism. For instance, a report from Business Standard (2019) estimates that nearly 80% of South Mumbai's prime wards could be submerged by 2050. Given that Mumbai is India’s financial hub, this could disrupt businesses, reduce property values, and displace large populations, adding to economic instability.

Similarly, cities like Jakarta, Bangkok, and Ho Chi Minh City face similar threats, risking trillions of dollars in real estate and infrastructure damages. As these cities are economic centers for their respective countries, the impacts would ripple through their national economies, affecting GDP growth and business operations.

The Economic Burden of Health Impacts

Climate change isn’t just wreaking havoc on the environment; it’s also taking a significant toll on public health, which in turn carries a hefty economic burden.

Rising temperatures and changing precipitation patterns expand the range of disease vectors such as mosquitoes, which thrive in warmer climates. This has led to the spread of diseases like malaria and dengue into new regions, putting a strain on healthcare systems. The economic cost of treating these health conditions, combined with a less healthy workforce, adds a complex layer to the overall economic burden of climate change.

For example, malaria, historically restricted to tropical and subtropical areas, is being reported in parts of the United States due to warmer climates that support the breeding of malaria-carrying mosquitoes.

According to a report by VaccinesWork (2023), the United States had issued a health alert after cases of locally-transmitted malaria were identified in the states of Florida and Texas. And, it was the first time in 20 years that the disease had spread locally in the country.

Extreme weather events also increase the risk of injury, heat-related illnesses, and psychological health concerns due to added stress from environment-related problems, such as flooding, deforestation, and air pollution. For instance, after Hurricane Katrina, many survivors faced long-term health issues exacerbated by the poor living conditions in temporary camps and the increase in respiratory illnesses due to mold contamination and air pollution. These patterns have been observed globally in disaster-prone regions, indicating that climate change can amplify the health impacts of environmental stressors.

These health impacts translate into increased healthcare costs, reduced labour capacity, and lower overall productivity. The World Health Organization estimates that by 2030, climate change could cause an additional 250,000 deaths per year, primarily from malnutrition, malaria, and heat stress. The economic cost of these health impacts is projected to reach between $2 to $4 billion per year by 2030.

Agriculture: The Disappearing Harvest

Agriculture is one of the sectors most vulnerable to climate change. Shifting weather patterns, extreme heat, and water scarcity are all contributing to reduced crop yields and lower food production. For farmers, this means lower incomes, higher debt, and an increased risk of bankruptcy. For consumers, it means rising food prices and increased food insecurity.

According to the CEEW report (2015), the climate change results in significant losses for India in the agricultural sector among other sectors. In India, the production losses in rice, wheat, and maize alone could go up-to $208 billion and $366 billion in 2050 and 2100, respectively.

Climate Migration: The Rising Tide of Economic Strain

Rising sea levels, desertification, and extreme weather are driving an increase in climate-induced migration. As per the World Bank, by 2050, it’s estimated that over 216 million people could be displaced by climate change. This mass migration will place immense pressure on economies and also impact the health sector, as overcrowded refugee camps increase the risk of disease transmission, particularly in urban areas as displaced populations seek refuge in cities.

The lack of adequate healthcare facilities and sanitation can lead to the spread of water-borne and respiratory diseases, while the psychological burden of displacement and loss can result in long-term mental health issues among displaced populations.

The economic cost of climate migration is multifaceted. It includes the direct costs of relocating and housing displaced individuals, the strain on local infrastructure, and the loss of productivity as people leave their jobs and homes behind. For receiving regions, there is the additional challenge of integrating these populations into the workforce, providing social services, and maintaining social cohesion.

The Economic Fallout of Ecosystems

 Ecosystems provide services such as pollination, water purification, and soil fertility, all of which are crucial for economic stability. As climate change disrupts these ecosystems, the cost of maintaining agricultural productivity, water quality, and other ecosystem services increases.

For instance, the decline in bee populations due to rising temperatures and habitat loss has already cost the agriculture industry billions in lost pollination services. Similarly, the degradation of coral reefs, which act as natural barriers against storms and provide habitat for fisheries, has increased the vulnerability of coastal economies to climate-induced damage.

Investing in Resilience: The Economic Case for Climate Action

While the economic cost of climate change is daunting, investing in resilience and adaptation can yield significant economic benefits. A 2019 report by the Global Center on Adaptation found that investing $1.8 trillion in climate resilience measures by 2030 could generate $7.1 trillion in economic benefits. These investments include infrastructure upgrades, improved water management, and the development of early warning systems.

For businesses, embracing sustainable practices isn’t just about mitigating risk; it’s about seizing new opportunities. According to the United Nations' report, the transition to a low-carbon economy is expected to create $26 trillion in economic value and generate over 65 million new low-carbon jobs by 2030.

The Path Forward: Turning Crisis into Opportunity

The economic cost of climate change is a clarion call for urgent action. The price we pay today will pale in comparison to the cheque of inaction coming due tomorrow. But with every crisis comes opportunity. By investing in climate resilience, embracing sustainable practices, and transforming our economies, we can not only avert the worst financial impacts of climate change but also unlock a wealth of new economic opportunities.

It’s time to recognize that the true cost of climate change isn’t just measured in the billions of dollars lost to disasters or the percentage points shaved off GDP. It’s measured in the resilience of our communities, the health of our ecosystems, and the stability of our economies. By acting now, we can build a future where the price of a melting planet is never paid again.
