Remove run massively due to climate change

Global warming is forcing hundreds of millions of people to leave their habitats. If that situation continues, we will have to witness the biggest migrations in human history.

A report by the International Organization for Migration (IOM) predicts at least 200 million people will leave their homes for environmental reasons from now until 2050. In the worst case scenario, that number could up to 700 million.

CARE International and Columbia University (USA) interviewed more than 2,000 migrants in 23 countries on why they left their homes. The results show that environmental issues are causing a population shift.

192 countries are negotiating to reach an agreement on global warming. The dark scenario of the largest migration phenomenon in human history due to natural disasters and environmental pollution may be included in this agreement. The draft document calls for countries to prepare plans to adapt to mass migrations caused by climate change.

According to IOM, people living in the deltas of major rivers in the world can suffer from the consequences of melting. Residents living near the desert will face increasing drought, while those living on islands may lose land because of rising sea levels.

Researchers do not evaluate conflicts related to climate change. But they stressed that one of the factors that caused the war in Sudan's Darfur region was the dispute over water and grassland . Concerns about the risk of water-related conflict outbreaks are increasing day by day in many parts of the world.

The IOM report predicts 40 island nations may disappear (partially or completely) if the sea level rises by 2 meters. The Maldives - made up of 1,200 islands in the Indian Ocean, plans to abandon some islands and build dams on the remaining islands. In addition, the island nation also considered the possibility of bringing all 300,000 people to another country.

The melting of the Himalayas could lead to frequent floods in the Ganges, the Mekong, the Yangtze and the Yellow River. These 4 rivers provide 1.4 billion people (nearly a quarter of the global population) in India, Southeast Asia and China. After the flood will be drought because there is no ice to supply water to the rivers.

In Mexico and Central America, severe droughts and typhoons have caused major migrations since the 1980s . The situation here will get worse in the coming decades. 'Natural disasters only cause short-term migration, which means that people only leave their homes for a certain period of time. Most migration will take place within national boundaries, from rural areas to cities , 'said Charles Ehrhart, a researcher at CARE International.
