The World’s Newest Type of Migrants: Climate Refugees

With climate change rendering entire countries uninhabitable, people are forced to leave their homes and seek refuge elsewhere.

In recent years, there have been growing concerns and conversations about climate change’s effects on the Earth. With warmer summers, retreating coastlines and record-breaking natural disasters, it is clear that the Earth is changing, and quickly. However, one aspect of the issue that is often overlooked is the displacement it causes among residents in climate change hot spots. As climate crises happen all over the world, more and more people—often called climate refugees—are forced to leave their homes to find a safe living environment elsewhere. 

In 2019, around 8.5 million people fled their homes for another part of their country because of violence and conflict. That same year, almost 25 million were internally displaced due to extreme weather and natural disasters caused by climate change. People are not only being internally displaced, however. In some cases, it is necessary for them to cross borders. 

One country facing drastic climate change problems is Kiribati, an island nation in the Pacific. Since the islands are extremely low-lying, rising sea levels are a major concern. So far, the elevated sea levels have caused coastal erosion, flooding and freshwater contamination. Because of this, one native, Ioane Teitiota, gathered his family and moved to New Zealand for a better life. 

Once climate refugees are forced to leave their countries, they face one main obstacle: legally, they are not “refugees” at all. Under the 1951 Refugee Convention, a refugee is a person who has fled their country due to persecution. Under international law, those migrating due to weather and climate change do not meet this criteria. Therefore, when people leave their country for climate reasons, they find themselves legally vulnerable and unable to claim the rights and protections provided to refugees. In most cases, their only option is to apply for some sort of temporary protection. 

In Teitiota’s case, he and his wife only received work visas, which expired in four years. Facing deportation, Teitiota applied for protection in New Zealand, arguing that his family was at risk back home in Kiribati due to the destruction climate change had caused to the islands. New Zealand rejected his plea and, in January 2020, the United Nations backed the decision.

The number of climate refugees is increasing, and there are projected to be 200 million displaced due to climate change by 2050. With this urgency, human rights activists are fighting for some sort of policy on the rights and protections of climate refugees, especially because countries that contribute the least to global climate change are often the ones hit hardest by its effects.

Teitiota was eventually deported to Kiribati. Still, experts still see a silver lining in his case. When reviewing New Zealand’s decision to reject Teitiota’s appeal, the U.N. reasoned that although the rising sea levels will “render Kiribati uninhabitable … the time frame of 10 to 15 years could allow for intervening acts by Kiribati, with the assistance of the international community, to take affirmative measures to protect and relocate its population.” 

The reason the U.N. committee provided for the rejection is that climate change’s threat to Teitiota’s life is not imminent enough—there is still time to help Kiribati. For the first time, the U.N. also declared that in life-threatening situations, countries should not send climate refugees back home. Although the ruling denied Teitiota’s claim to protection in New Zealand, it paves the way for other climate refugees to receive it. The ruling is not internationally binding, but is a step toward bettering the situations of climate refugees.

While governments and international organizations are making strides to put adequate structures in place, many think much more work needs to be done. There are people like Teitiota fleeing their climate change-ravaged countries every single day.
