Global temperatures have increased at an unprecedented pace in the past 40 years and significant further warming could occur. All countries will feel the direct negative effects of unmitigated climate change, but this paper finds that the economic costs of temperature increases will likely fall disproportionately on countries with hot climates, such as most low-income countries. Sound domestic policies and institutions can help reduce the adverse consequences of weather shocks, but only to a limited degree. The international community must play a key role in supporting low income countries’ efforts to adapt to climate change. Only continued international cooperation and a concerted effort to stem greenhouse gas emissions can limit the long-term risks of climate change.
