Florence
It’s no coincidence that there is a new natural disaster in the news every day around the world — the earthquake and tsunami that just hit Indonesia; Typhoon Mangkhut in East Asia; Hurricane Florence in the Carolinas; monsoon flooding in Bangladesh; and Hurricane Michael in the Florida Panhandle are just a few of the storms that saturate our daily media sources.

Scientists agree that rising sea levels and sea temperatures as a result of climate change are increasing the frequency and intensity of such disasters. Research shows that climate-change-related natural disasters will disproportionately affect the world’s poorest countries and citizens. These environmental events are just one example of the many ways that sea changes are hurting the world’s poor.

Rising Sea Levels Hurt Agriculture

According to a 2015 World Bank report, “agriculture is one of the most important economic sectors in many poor countries. Unfortunately, it is also one of the most sensitive to climate change, given its dependence on weather conditions: from temperature, sun and rain, through climate-dependent stressors (pests, epidemics, and sea level rise).” This effect is felt by farmers — usually the poorer citizens of poor countries — who find their livelihoods threatened by natural disasters and the heavy flooding that wipes out their crops.

When agriculture suffers, the price of food skyrockets. This change then leaves families who already struggle to acquire adequate nutrition in an even more dire situation. Statistics show that poor families already spend a huge percentage of their income on food, and the World Bank predicts there may be 73 million people pushed into extreme poverty by 2030 from the rising costs of food alone.

Rising Sea Temperatures Breed Disease

The World Bank report says a small rise in sea temperatures “could increase the number of people at risk for malaria by up to 5 percent, or more than 150 million more people affected. Diarrhea would be more prevalent, and increased water scarcity would have an effect on water quality and hygiene.”

People who don’t have access to clean water, generally people living in poverty, would be at the greatest risk of developing diseases and they often lack the resources to treat infectious or bug-borne diseases once a family member is infected. The report, which called for climate-informed development, concludes by saying that poverty reduction and climate change can’t be treated separately, as the two go hand-in-hand.

Refugees

There are over 1600 confirmed deaths in Indonesia after an earthquake and tsunami hit the island of Sulawesi on October 5th, 2018. In fact, the U.N. stated that over 190,000 people are in need of urgent help — aftershocks have caused the destruction of 2,000 homes due to mudslides and makeshift refugee camps are being set up. At the most basic level, these events are pushing already poor people into extreme poverty through the destruction of their homes, forcing them to resettle elsewhere.

A 2017 Cornell study found that rising seas could cause 2 billion refugees by the year 2100 (these are truly climate change refugees).  This means that around one-fifth of the world’s population will be made homeless by climate change. The effects will be felt most strongly by people living on coastlines, and those in the world’s poorest countries will suffer the most.

As the seas warm and rise, research shows that the frequency and intensity of these disasters will rise as well, forcing more and more people to abandon their homes.

Sea Changes and the Poor

Rising sea temperatures are a result of global warming’s effects on ocean habitats and the human communities that depend on them.

The authors of an article about how poor countries and fisheries are the most negatively impacted by warming seas found that, “despite having some of the world’s smallest carbon footprints, small island developing states and the world’s least-developed countries will be among the places most vulnerable to climate change’s impacts on marine life.”

Actions for the Future

Andrew King, a climate researcher at the University of Melbourne in Australia and the author of a study from the AGU on global warming, argues that: “The results are a stark example of the inequalities that come with global warming…the richest countries that produced the most emissions are the least affected by heat when average temperatures climb to just 2 degrees Celsius [3.6 degrees Fahrenheit] while poorer nations bear the brunt of changing local climates and the consequences that come with them.”

There are ideas for how to better protect these places in the future to be prepared for these sea changes. Long term, the solution will be tackling climate change head-on.

Climate Change Refugees
Given the contemporary discussion about refugees, which focuses primarily on those who have been forced from their homes because of conflict or persecution, it is important to evaluate other push factors for refugees around the world. Here are five facts you should know about Vanuatuan refugees — the first climate change refugee.

  1. Officially, Vanuatu has no refugees, either ingoing or outgoing.
    According to the 1951 Convention Relating to the Status of Refugees, which provides the international legal definition of refugee and establishes states’ responsibilities to them, Vanuatu is not home to any refugees. Vanuatu’s official refugee population reached a high in 2010, with a total refugee population of four.
  2. However, Vanuatu is home to the world’s first “climate change refugees.”
    In 2005, the U.N. Environment Programme reported the forced inland movement of nearly 100 villagers in the province of Tegua in northern Vanuatu, citing the people as the world’s first climate change refugees. People in Vanuatu inhabit 65 of the 80 islands in the archipelago, and many live in coastal cities or villages.
    Because most of the infrastructure of small island nations is located along shallow coasts, countries like Vanuatu are vulnerable to rising sea levels and ever-increasing tropical storms. Since 2005, thousands of Pacific islanders, such as those from Kiribati, have been forced to move to larger islands like Fiji, where they often experience difficulty integrating into society.
  3. This may be just the beginning.
    A 2013 report by the Intergovernmental Panel on Climate Change revealed that climate change could cause sea levels to rise by as much as 3 feet by 2100. For low-lying island nations, this change could be catastrophic. In Vanuatu, a rise in sea level of this proportion would require the forced relocation of thousands. And Vanuatu wouldn’t be alone; its population of 277,000 represents just a small portion of the hundreds of millions of people around the world who live along coasts.
  4. Open-Source data provides hope and information for potential climate change refugees. Collaboration between the U.N. Framework Convention on Climate Change and the governments of Vanuatu, Tonga, Samoa and Papua New Guinea created The Vanuatu Globe. This open-source data platform maps low-lying coastal areas to help citizens and governments alike identify areas facing the greatest risk of coastal flooding from rising sea levels.
    Over 1,000 people accessed the data set within days of Tropical Cyclone Pam in 2015. The platform aided recovery efforts and initiatives to improve infrastructure and prevent future devastation.
  5. Work is being done to prepare in Vanuatu and elsewhere.
    The Capacity Building for the Development of Adaptation Measures in Pacific Island Countries Program, established in 2002, represents just one of many initiatives working with island nations to reinforce infrastructure and make sound development decisions under the looming threat of climate change. Capacity-building programs such as this, complemented by expanded access to mapping data, will help citizens and leaders prepare for large-scale environmental shifts.
