Global warming is causing the polar ice caps to melt and This triggers a rise in sea level. There are many coastal cities that, if the sea level continues to rise, they will be left without any coastline. People who have to move or migrate to other areas due to this rise in sea level or for other causes related to the increased frequency and intensity of extreme weather events (such as hurricanes, floods, droughts ...) they are called climate refugees.
It is estimated that by the year 2100, some two billion people (this will be one fifth of the world's population by then) could become climate refugees, mainly due to the rise in the level of the oceans.
Climate change and refugees
Millions and millions of people live in coastal cities that are increasingly threatened by extreme weather events such as hurricanes, floods, and rising sea levels caused by climate change. These people who have their life, their family, friends, work and so on, they are forced to move to other safer and more habitable areas of the interior for a longer time.
A study has been conducted at Cornell University that states that we are going to have more and more people in a world with less land and that this will happen sooner than we think.
With rising sea levels, all the people living in coastal areas will have to migrate to safer areas inland. On the other hand, the world's population is only growing every year. So all this leads to having to house more and more population in less habitable territory. Charles geisler Emeritus Professor of Developmental Sociology at Cornell University, he explains that future sea level rise is not going to develop progressively, but may start to rise very quickly. Despite these increasingly accurate predictions from the scientific community, politicians are not taking stock of the significant barriers to entry that coastal climate refugees, Like other refugees, they will find them when they migrate to higher ground.
Future predictions
According to United Nations reports, the world population is expected to increase to 9.000 billion people by 2050 and 11.000 billion by 2100. However, we will have less arable land, less space to develop the population, and rising sea levels will destroy many arable areas, such as river deltas, fertile areas, etc. And all this will lead people to have to look for new places to live.
Approximately, 2.000 billion people could be climate refugees by 2100. The colliding forces of human fertility, submerging coastal areas, residential retreat and impediments to resettlement inland are a huge problem. By then there will be many large-scale problems such as climate refugees, wars for natural resources, a decrease in the productivity of the planet, areas will be needed to store greenhouse gases that compensate for the melting of permafrost and deforestation, etc. The predictions are somewhat grim for the future that awaits present generations.
The document outlines tangible solutions and proactive adaptations in places like Florida and China that coordinate coastal and inland land use policies in anticipation of climate-induced population changes. Florida has the second longest coastline in the entire United States and there has been a coastal exodus that is reflected in the State's Comprehensive Planning Law.
It is not only the elevation of the sea that is of concern, but also other extreme phenomena such as hurricanes or tropical storms can push sea water inland. Historically, humans have devoted considerable effort to reclaiming land from the oceans, but now they live with the opposite: the oceans reclaim the land spaces of the planet
