Limiting global warming to 1.5℃ is very likely to positively impact GDP per capita across Africa. Increasing economic damage forecasts under high emissions diverge from low emission pathways by 2030. Inequalities between African countries are projected to widen with increased warming. Across nearly all African countries, GDP per capita is projected to be at least 5% higher by 2050 and 10-20% higher by 2100 if global warming is held to 1.5℃ compared with 2℃.
