The walls at Saifullah’s northern Jakarta home are shaped like tree rings. They indicate how high floodwaters have reached each yearly — some 4 feet above the damp dirt floor.

When the water level is too high, Saifullah sends his family to stay with their friends. In the event that the pump fails, he either uses a bucket, or waits for the water to recede.

“It’s normal here,” Saifullah (73), said. “

Jakarta is the world’s fastest-sinking major city. The Indonesian government plans to relocate its capital 1,240 miles (2,200 kilometers) to the island of Borneo. It will also move 1.5 million civil servants.

This is a major undertaking that forms part of the mass movement expected to increase in the coming years.

An astonishing 143 million people are likely to be displaced by rising seas and droughts over the next 30 year, according to the Intergovernmental Panel on Climate Change report, published Monday by United Nations.

Governments in Asia are already trying to address it.

One third of all migrants to the world are from Asia. With megacities like Jakarta and rural villages becoming less viable, scientists have predicted that migration flows will continue to grow.

The report stated that under all levels of global warming, certain regions that are densely populated now will become uninhabitable or unsafe.

According to one estimate, 40 million South Asians may have to relocate in the next 30 years due to drought, crop failures, and other natural disasters.

Rising temperatures are of particular concern to Chris Field, an environmental scientist at Stanford University who also chaired previous U.N. reports.

He said that there are very few places that are too hot for people to live in right now. “

There is no nation that offers asylum or any other legal protections for people who have been displaced by climate change. However, the Biden administration studied the issue.

People move away from their homes for many reasons, including poverty and violence. But what’s happening to Bangladesh is a clear demonstration of the impact climate change has on people, according to Amali Tower, the founder of Climate Refugees.

Scientists have predicted that 2 million people may be forced from their low-lying countries by rising sea levels by 2050. More than 2,000 migrants are already arriving in Dhaka, the capital, every day, many fleeing to coastal areas.

Tower stated that you can see the movement of people. The increasing number of disasters is tangible.

Migration flows can be slowened if countries such as the United States and European countries act now to reduce their greenhouse gas emissions to zero. Other countries believe richer countries should grant humanitarian visas to those from disproportionally affected countries.

The U.N. report states that dealing with climate migrants will be a key policy issue in Sub-Saharan Africa, Latin America, and Latin America over the next few decades. In Asia, where nearly two-thirds could live in cities in the next 30 years,

“It’s basically people migrating out of rural areas and then possibly squatting somewhere,” Abhas Jha, a manager at the World Bank’s Climate Change and Disaster Risk Management program in South Asia, said.

Migration doesn’t need to be a crisis. Vittoria Zanuso is the executive director of The Mayors Migration Council. This global group includes city leaders.

Officials are creating shelters for climate migrants in Dhaka’s northern capital. Zanuso stated that they are also working with smaller cities to become “climate havens” which welcome migrants.

She said that the influx of new workers gives smaller cities an opportunity to grow economically. “

She said that in the coming years, it will be crucial to prepare cities for the influx. “
