What happens to Africa if climate change goes unchecked?

Via Susan Comrie, I came across this alarming map of what the world will look like if global temperatures rise by 4°C.  The outlook for Africa is extraordinarily grim.  (The blue dots north of the Sahara reflect potential for solar energy installations, and the red bits are coastline permanently lost to sea level rise.)

A map showing that Africa will mostly be desert at 4 degrees Celsius of global warming, with a bit of greenery in the Sahel

According to Our World in Data, the world’s current set of climate policies will lead to warming of 3.1-3.7°C relative to pre-industrial temperatures by 2100.  That’s not too far off the future depicted in this map.

There’s a desperate need for the countries which emit the most carbon — primarily China, the US, and the European region — to put better policies in place.  African countries also need to plan for climate change mitigation, although it’s unclear exactly how much can be done in the face of 4°C of warming.
