“The Great Climate Migration Has Begun”

June 15, 2021 by 2050kids in Climate Change, Displacement and Migration

In 1990, the Intergovernmental Panel on Climate Change (IPCC) noted that the greatest single impact of climate change could be on human migration—with millions of people displaced by shoreline erosion, coastal flooding, and agricultural disruption. Since then various analysts have tried to put numbers on future flows of climate migrants (sometimes called “climate refugees”)—the most widely repeated prediction being 200 million by 2050. Migration and Climate Change. IPCC

While estimates on the number of climate refugees by 2050 range from 25 million to 1 billion, the United Nations number — 200 million — is most frequently cited.

The New York Times Magazine last year produced a three-part interactive detailing in vivid detail individual people from around the world who have already been forced to migrate due to the impacts of climate change. The Great Climate Migration, a collaboration with Pro Publica and supported by The Pulitzer Center noted: “As their land fails them, hundreds of millions of people from Central America to Sudan to the Mekong Delta will be forced to choose between flight or death. The result will almost certainly be the greatest wave of global migration the world has seen.”

Even as hundreds of thousands of Guatemalans fled north toward the United States in recent years, in Jorge’s region — a state called Alta Verapaz, where precipitous mountains covered in coffee plantations and dense, dry forest give way to broader gentle valleys — the residents have largely stayed. Now, though, under a relentless confluence of drought, flood, bankruptcy and starvation, they, too, have begun to leave. Almost everyone here experiences some degree of uncertainty about where their next meal will come from. Half the children are chronically hungry, and many are short for their age, with weak bones and bloated bellies. Their families are all facing the same excruciating decision that confronted Jorge.

The odd weather phenomenon that many blame for the suffering here — the drought and sudden storm pattern known as El Niño — is expected to become more frequent as the planet warms. Many semiarid parts of Guatemala will soon be more like a desert. Rainfall is expected to decrease by 60 percent in some parts of the country, and the amount of water replenishing streams and keeping soil moist will drop by as much as 83 percent. Researchers project that by 2070, yields of some staple crops in the state where Jorge lives will decline by nearly a third.

In March, Jorge and his 7-year-old son each packed a pair of pants, three T-shirts, underwear and a toothbrush into a single thin black nylon sack with a drawstring. Jorge’s father had pawned his last four goats for $2,000 to help pay for their transit, another loan the family would have to repay at 100 percent interest. The coyote called at 10 p.m. — they would go that night. They had no idea then where they would wind up, or what they would do when they got there.

From decision to departure, it was three days. And then they were gone.

In a Brookings Institute report The climate crisis, migration, and refugees, the authors outline the major challenges the world faces due to climate change:

  • Large-scale human migration due to resource scarcity increased frequency of extreme weather events, and other factors, particularly in the developing countries in the earth’s low latitudinal band
  • Intensifying intra- and inter-state competition for food, water, and other resources, particularly in the Middle East and North Africa
  • Increased frequency and severity of disease outbreaks
  • Increased U.S. border stress due to the severe effects of climate change in parts of Central America

However, they project that “the scope and scale of human migration due to climate change will test the limits of national and global governance as well as international cooperation.”

In 2018, the World Bank estimated that three regions (Latin America, sub-Saharan Africa, and Southeast Asia) will generate 143 million more climate migrants by 2050. In 2017, 68.5 million people were forcibly displaced, more than at any point in human history. While it is difficult to estimate, approximately one-third of these (22.5 million to 24 million people) were forced to move by “sudden onset” weather events—flooding, forest fires after droughts, and intensified storms. While the remaining two-thirds of displacements are the results of other humanitarian crises, it is becoming obvious that climate change is contributing to so-called slow onset events such as desertification, sea-level rise, ocean acidification, air pollution, rain pattern shifts and loss of biodiversity. This deterioration will exacerbate many humanitarian crises and may lead to more people being on the move.

The NYT/ProPublica project finds:

People are already beginning to flee. In Southeast Asia, where increasingly unpredictable monsoon rainfall and drought have made farming more difficult, the World Bank points to more than eight million people who have moved toward the Middle East, Europe and North America. In the African Sahel, millions of rural people have been streaming toward the coasts and the cities amid drought and widespread crop failures. Should the flight away from hot climates reach the scale that current research suggests is likely, it will amount to a vast remapping of the world’s populations.
