Climate change threatens to increase global poverty, especially in developing countries. As the earth warms, developing nations experience greater economic losses from more frequent natural disasters, averaging 13.4% of GDP annually. By 2020, climate change may increase the proportion of the world's poor from 53% to 70%. Poor communities are most vulnerable to climate change because they depend most on natural resources and have less ability to withstand climate variability. Overall, climate change exacerbates poverty worldwide, particularly in developing nations.
