Vulnerable nations face mounting climate crisis despite minimal contribution to emissions

Climate change keeps causing serious hardships worldwide, but the impacts are far from evenly spread. A detailed review, pulling insights from trusted sources like the Notre Dame Global Adaptation Initiative and the Germanwatch Climate Risk Index, makes it clear that the countries most vulnerable to climate effects generally contribute very little to global emissions yet face the worst consequences. Looking back from 1993 to 2022, extreme weather events have claimed over 765,000 lives and caused damages totaling approximately $4.2 trillion. These devastating impacts highlight just how urgent and necessary targeted climate actions are.

At the core of climate vulnerability are three main factors: first, exposure—meaning how much a country faces risks like floods, droughts, storms, or rising sea levels; second, sensitivity—the degree to which populations, economies, and ecosystems are affected; and third, adaptive capacity—the ability of a nation to respond effectively through institutions, innovative technology, and available resources. Countries that are highly exposed and sensitive but have weak adaptive capacity tend to be the most at risk. Interestingly enough, wealthy nations like Australia and the U.S., despite facing serious climate threats, tend not to be classified as highly vulnerable because they typically have better resources and measures in place. On the flip side, many developing countries are suffering greatly due to poverty, fragile infrastructure, weak healthcare systems, reliance on climate-sensitive sectors like agriculture, limited social safety nets, and political instability.

The ten countries sitting at the top of the vulnerability list—such as Chad, Somalia, Syria, the Democratic Republic of Congo (DRC), Afghanistan, South Sudan, Central African Republic (CAR), Sudan, Yemen, and Nigeria—depict a grim picture of intertwined climate, social, and political crises. For example, Chad, identified as the most vulnerable, is trapped in a paradox where severe droughts are worsened by destructive floods, leading to widespread agricultural breakdown—affecting around 80% of its population—and deep political unrest. Somalia’s situation is equally dire; five consecutive failed rainy seasons have devastated livestock, caused crop failures, displaced over a million people, and driven massive food insecurity, all compounded by ongoing conflict and a fractured governance system.

In Syria, the longest-running conflict of the 21st century intersects dangerously with climate shocks. Drought conditions preceding the 2011 war created social and economic strain, and the 2023 earthquake further damaged already fragile water and farming infrastructure, making displacement issues even worse. The Democratic Republic of Congo faces armed conflict, repeated flooding disasters—like the one in May 2023 that killed more than 500 people—and widespread food insecurity affecting nearly 26 million. Afghanistan is also struggling—its worst drought in thirty years is hitting as the country’s economy shrinks by roughly 35%, increasing humanitarian needs, especially under current sanctions restricting aid.

South Sudan is experiencing extreme temperatures—more than twice the worldwide average—and recent floods have affected almost a million people, destroying crops and increasing displacement. Ongoing civil war hampers effective aid and recovery efforts. Meanwhile, the Central African Republic faces resource conflicts caused by water and land shortages, along with health crises driven by climate-sensitive diseases and long-standing governance issues. Sudan is fighting desertification as the Sahara pushes southward, paired with unpredictable rainfall and stalling agriculture. Yemen’s climate struggles are layered on top of a severe humanitarian crisis, worsened by war, infrastructure damage, groundwater depletion, and hunger affecting about 17 million. Nigeria, the most populous country in Africa, suffers from severe floods, widespread damage to farming, and rising food insecurity, all intensified by regional conflicts exacerbated by climate pressures.

Regionally, hotspots like the Sahel are experiencing rapid temperature increases and desertification, while the Horn of Africa faces its worst drought in over forty years—leading to displacement and hunger. Small island nations are on the frontlines of sea-level rise, coastal erosion, and the collapse of marine ecosystems. Central America’s Dry Corridor has seen prolonged droughts paired with hurricanes, pushing millions into food insecurity and prompting migration. South Asia, home to nearly two billion people, contends with erratic monsoon patterns, dangerously high temperatures, massive flooding (such as in Pakistan in 2022), and melting Himalayan glaciers threatening water supplies.

The human toll is staggering. Every year, around 21.5 million people are forced to move internally because of climate disasters. This displacement also fuels migration across borders and sometimes permanent relocations. Food security faces serious challenges, as changing climate patterns reduce crop yields and mess with supply chains. Water scarcity, contamination, and over-extraction of aquifers are worsening problems, alongside glacier melting and saltwater intrusion. As urbanization continues rapidly, billions of city dwellers will soon live in areas highly vulnerable to climate hazards—by 2050, that number is expected to grow significantly.

One point that’s impossible to ignore in all this is the appalling inequality framing the crisis. The 50 most vulnerable countries—collectively—contribute only 0.28% of global CO2 emissions, yet they bear the brunt of the impacts. Meanwhile, developed nations—mainly responsible for most emissions—have emitted about 79% since 1850. To put it simply, the average American’s carbon footprint is around 100 times that of a citizen in Chad. The role of corporations is stark too; just 100 companies are responsible for 71% of industrial emissions. And despite commitments to climate finance, the actual flow of funds remains insufficient. While in 2022, the promised $100 billion for climate adaptation was finally surpassed with $115.9 billion, estimates indicate that between $194 and $366 billion annually will be needed by 2030 just to support adaptation efforts. The “loss and damage” fund established at COP27 faces hurdles—such as difficulties in getting binding commitments and operational challenges—that slow down timely assistance to those most in need.

The gender aspect adds another layer of complexity. Women and girls are disproportionately affected—they often work in climate-sensitive sectors, shoulder additional care responsibilities during crises, and are more exposed to violence under stressful conditions. Moreover, their voices are underrepresented in climate decision-making processes, which hampers efforts to create equitable solutions.

But it’s not all bleak—there are positive examples of resilience giving hope. For instance, early warning systems in Bangladesh have dramatically reduced cyclone-related fatalities, and ecosystem restoration projects in places like Costa Rica and Senegal help protect communities and biodiversity. The Netherlands has developed innovative “Room for the River” initiatives, which combine flood defenses with nature-based solutions. To replicate and scale these successes, we need to ramp up climate finance dramatically—to around $2.4 trillion annually by 2030—and foster the transfer of technology, strengthen institutions, and offer debt relief to the most vulnerable nations. Digital innovations and community engagement can also play pivotal roles in early warnings, saving lives and cutting economic losses.

Looking to the future, climate models warn us that impacts will likely intensify unless major action is taken. By 2030, we could see global warming reaching 1.5°C, pushing an additional 100 million people into extreme poverty and displacing about 216 million more. Crop yields could decline by as much as 10%, and by 2050, two billion people might face serious water shortages. One billion could be affected by coastal flooding, and the economic damages could total up to $23 trillion worldwide.

For regions like the UAE and the larger Gulf, which sit at a crossroads of economic and geopolitical influences, these insights underscore urgent priorities. Boosting renewable energy, developing climate-resilient infrastructure, and fostering international cooperation are key strategies. Transitioning to solar power and clean technologies doesn’t just help cut emissions—it also strengthens the capacity of these regions to adapt to extreme heat and water scarcity. As climate change continues to unfold as one of the defining challenges of this century, the global community must act decisively. Bridging the gap between those who’ve caused the most damage and those suffering its consequences is crucial—no nation can do it alone.

Ultimately, responding effectively means more than raising alarms—it requires real, tangible steps: increasing climate finance, ensuring equity, implementing proven adaptation strategies, and supporting vulnerable countries. Every fraction of a degree of warming we avoid, and every effort we make to build resilience, could be the difference between survival and catastrophe for millions. This is a shared crisis that transcends borders and demands a unified, sustained global effort; after all, no one should be left behind.
