Refugee displacement can commonly be attributed to causes including war, persecution, and natural disasters. In the rapidly changing Anthropocene, a new reason may join that list: climate change. More specifically, its catastrophic impacts can destroy communities, infrastructure and agricultural land, forcing people to flee their homes in search of safer environments. In some cases, entire regions may become unsuitable for safe human living, leading to mass migrations and the creation of climate refugees. Deadly natural disasters occur more frequently and strike harder as a result of climate change. In November 2020, two Category 4 hurricanes hit Guatemala, Honduras and El Salvador, displacing thousands. Several phenomena can lead to the creation of climate refugees, including agricultural hardships, rising sea levels and natural disasters. Climate change dramatically impacts agriculture and can lead to bad harvests. Rising global temperatures can disrupt rainfall patterns, and increase the frequency and intensity of extreme weather events, such as droughts, floods, and heatwaves. These effects can disrupt the natural processes and lead to good shortages. Variability in weather patterns disrupts the delicate balance that farming relies on, causing difficulty for farmers to predict when to plant and harvest their crops. These unpredictable conditions can result in diminished agricultural productivity, threatening food security and economic stability in many regions across the globe. Farmers who rely on their crops being sold will often face financial hardship, food shortages, and poverty. In turn, these conditions can force people to abandon their homes and migrate for better opportunities and resources. Additionally, it can trigger social unrest and conflicts over scarce resources, further destabilizing regions. Climate refugees will only continue to increase as the number of agricultural issues does.
Another example of an effect of climate change is rising sea levels. From 1993 to 2020, the rate of global mean sea level rise was approximately 3.7 millimeters (0.15 inches) per year. While this may seem low, its effects are far more significant. Some countries most vulnerable to rising sea levels include the Maldives, Tuvalu, Indonesia, and even non-island countries such as India, Bangladesh, and China. Low-lying coastal areas and islands risk being submerged, causing mass migrations of those who live there. Rising sea levels can also erode land around the coast, causing more floods, which can destroy homes, damage infrastructure, and much more. In late 2022, Pakistan was hit by floods that killed over 1,000 people, marking it as the world’s deadliest flood since the 2020 South Asian floods. People living in these affected areas, which are often densely populated, will have to move in large numbers to higher land and other countries. This issue will only worsen if something isn’t done about the dangerous rise of sea levels.
Natural disasters were already a common cause of refugees having to migrate. Still, climate change has simply exacerbated the issue, leading to more and more tornadoes, floods, and hurricanes. For instance, the warming of sea surface temperatures in the Atlantic Ocean has been linked to the increasing intensity of storms. This is exemplified by Hurricane Katrina in 2005 and Hurricane Harvey in 2017, which caused widespread devastation. Natural disasters may very well be the most significant cause of the creation of climate refugees because of how the Anthropocene’s effects help contribute to their increase. They can easily wipe out entire cities and populations, destroying homes and resources and causing large numbers of people to move. This causes many social, political, and economic issues as well. Many neighboring countries are simply not equipped to deal with large numbers of climate refugees.
On a political level, the influx of displaced people can cause social strain. Competition for limited resources in host countries can lead to tensions and conflicts, potentially fueling political unrest and violence. Economically, hosting climate refugees can burden local economies. The demand for housing, healthcare, education, and social services increases, putting pressure on insufficient resources. This can lead to pressure on public finances, potentially resulting in reduced investments in infrastructure. Addressing the root causes of climate change and developing complete procedures for climate-induced migration is crucial to mitigating these political and economic challenges.
The era of the Anthropocene has profound implications for the increase of climate refugees. As humans continue to alter the Earth, the consequences of this change are increasingly evident. Rising sea levels, extreme weather events, droughts, and resource scarcity drive societies from their homes, and the number of climate refugees is likely to grow in the coming years. The Anthropocene urges us to recognize our role in climate change, protect vulnerable populations, and address the root causes of climate-induced migration. The global community must come together to support those affected and work towards a more sustainable, resilient future that mitigates the factors contributing to the creation of climate refugees.
