If the world is 7°C warmer, there will be more forests and grasslands and less deserts. You would expect deserts to expand but actually deserts will shrink. Ice caps and tundras will be covered with temperate forests, with the exception of a small part of antarctica which will be cold enough to sustain a taiga (boreal forest). The Sahara desert will heat so much in summer that it pushes the African monsoon much farther north. Most of Sahara will be tropical rainforest with some tropical monsoon forests and savannas. The cold currents causing desert climate in west coasts of South America and Africa will no longer be cold, so they will be covered with tropical rainforests. The central Asian deserts will mostly be short grass savannas. The center will retain some of the desert and the outer edges will be covered with tall grasslands savannas. Extreme outer edges will be covered with subtropical forests in the northern edges, and tropical rainforests and monsoon forests in the southern edges. Most of Antarctica will be covered with temperate forests, with some boreal forests. The center of the continent will be covered with grasslands, tall and short grass. Australia will be covered with tropical rainforests, tropical monsoon forests and grasslands in the most inland areas.
In this new world, the most common biomes arranged in descending order are:-
1. Tropical rainforests
2. Subtropical forests
3. Tropical monsoon forests.
4. Temperate forests.
5. Deserts
6. Boreal forests
With no tundras and ice caps.
