Environment Scorching futuristic vision and the inevitability of migration Early 21st century

In the early to mid-21st century, humanity faces two enormous trends. One is a rapidly growing population, and the other is accelerating global warming. The world's population exploded in the second half of the 20th century, already surpassing six billion in the early 2000s. The United Nations estimates that the population will reach nearly nine billion by 2050, and it is becoming clear to all that the Earth's limited resources are under pressure. At the same time, carbon dioxide emissions from our continued dependence on fossil fuels since the Industrial Revolution are steadily causing temperatures to rise, and the 2001 IPCC Third Assessment Report predicts that the average global temperature will rise 1.4 to 5.8 degrees Celsius by the end of the 21st century, warning that this will radically alter the conditions for future human existence.

Emerging against this backdrop is the shocking prediction that billions of people will be locked out of the climatic conditions that humanity has always found comfortable. Human civilization has long adapted to average temperatures in the range of 13 to 25 degrees Celsius. Agriculture, cattle raising, and urban activities have been built on this environment. However, as warming temperatures combine with population pressures, this climatic zone will shift northward, transforming vast areas of existing habitation into harsh environments. Studies suggest that one to three billion people could be pushed out of their comfort zone, and if they refuse to migrate, one-third of the world's population could be left behind in a harsh land of average temperatures of 29°C or higher. Today, only 0.8% of the Earth's land mass meets these conditions, and most of it is confined to the Sahara Desert. In the future, however, this environment is expected to engulf billions of people.

This prediction is more than just an academic warning. Rising sea levels and flooding threaten Bangladesh, and droughts are worsening in the Sahel region of Africa. Since the epicenter of population growth is precisely in these regions, the combination of environmental crisis and population pressure makes the scenario of mass migration from uninhabitable places a real possibility. In addition, conflicts over labor migration and refugee admissions are shaking up politics in European countries, and the question of billions of people being forced to move globally is perceived as shaking up international politics and security, as well as the economic order itself.

Thus, the "billions of people could become uninhabitable" projection symbolizes a sense of crisis at the intersection of two currents: population explosion and global warming. If humanity refuses to migrate, a third of the population will be left behind in a scorching hot environment. This realistic vision of the future sharply confronts the world with both global climate change countermeasures and migration policies.
