Global warming could lead to extreme temperatures, particularly after 2050. The resulting heatwaves would pose major risks, especially to vulnerable regions across the tropics.
The countries most susceptible to the impacts of global warming are primarily developing nations[1], such as those in the Sahel[2], the Middle East[3] and the Mediterranean, which naturally have hot climate. Rising temperatures could turn these regions into desert, destroy livestock, and push them toward the temperature threshold of human habitability in the coming decades[4].
Many of these nations already face challenges such as limited resources and political instability, which hinder their ability to adapt quickly to climate change. As a result, their populations may be forced to migrate toward cooler northern regions, potentially leading to border conflicts and guerrilla warfare.
