Climate change in Africa

Graph showing temperature change in Africa between 1901 and 2021, with red colour being warmer and blue being colder than average (The average temperature during 1971–2000 is taken as the reference point for these changes.)

Climate change in Africa is an increasingly serious threat as Africa is among the most vulnerable continents to the effects of climate change.[1][2][3] Some sources even classify Africa as "the most vulnerable continent on Earth".[4][5] Climate change and climate variability will likely reduce agricultural production, food security and water security.[6] As a result, there will be negative consequences on people's lives and sustainable development in Africa.[2]

Over the coming decades, warming from climate change is expected across almost all the Earth's surface, and global mean rainfall will increase.[7] Currently, Africa is warming faster than the rest of the world on average. Large portions of the continent may become uninhabitable as a result of the rapid effects of climate change, which would have disastrous effects on human health, food security, and poverty.[8][9][10] Regional effects on rainfall in the tropics are expected to be much more spatially variable. The direction of change at any one location is often less certain.

Observed surface temperatures have generally increased by about 1 °C in Africa since the late 19th century to the early 21st century.[11] In the Sahel, the increase has been as much as 3 °C for the minimum temperature at the end of the dry season.[11] Data for temperature and rainfall shows discrepancies from the norm, both in timing and location.[12][2][13]

For instance, Kenya has a high vulnerability to the impacts of climate change. The main climate hazards include droughts and floods as rainfall will likely become more intense and less predictable. Climate models predict that temperatures will rise by 0.5 to 2 °C.[14] In the informal urban settlements of Nairobi the urban heat island effect adds to the problem as it creates even warmer ambient temperatures. This is due to home construction materials, lack of ventilation, sparse green space, and poor access to electrical power and other services.[15]

The African Union has put forward 47 goals and corresponding actions in a 2014 draft report to combat and mitigate climate change in Africa.[16] The International Monetary Fund suggested in 2021 that $50 billion might be necessary to cover the costs of climate change adaptation in Africa.[17][18][19]
