In 25 million years future the world is 1 degree hotter than 2010, and rain forests cover the equator but Africa-like savannas are dominant. In the sea dolphins hold their niche but seals filter feed and otters have taken the role of seals and the ambush predator niche north of the equator, where they can't compete with the better adapted crocodilians. An order of primates descended from the Hamadryas baboon start to compete with carnivora for the niche of apex predators.
California has separated and drifted north west, and is covered in lush forests.
--Biomes: California Forest.
North America has
separated from South America (though
not by much) and moved slightly North, causing huge taiga in the North,
forests around the current U.S.-Canadian border and around the coasts,
huge prairie in the center, in Central America is a rainforest, and the
south-eastern corner of the U.S. (around Florida to Louisiana, north to
Southern Missouri (due to Mississippi river) and north to South
Carolina) is a huge swamp.

Forest, Taiga, Swamp.
South
America has drifted slightly northward, causing the entire Northern 2/3
to be covered in rain forest, and the southern third to be covered in
savannah.
--Biomes: Savanna, Rain Forest.
Africa has crashed into Gilbratar, blocking off the Mediterranean and causing it to dry out, forming a huge salt desert. The northern half of Africa is dry savannah with Acaica plants littering the landscape, similar to todays African Savannah.
--Biomes: Rain
Forest, Savanna.
Europe’s
western and northern side is covered in forest, the southeastern side is
covered in prairie.
--Biomes: Grassland,
Forest.
Asia is covered in rain forest to the
south-east, the center of Asia in a huge strip is covered in forest, and
now-Russia is covered in taiga. There is also a huge desert in the area
of the Gobi desert today.
--Biomes: Desert, Forest, Rain Forest,
Taiga.
Australia has moved northward to the
equator and crashed into Papua New Guinea, it is now covered in rain
forest everywhere except for the central savannah, not too different
from Africa’s savannah.
--Biomes: Rain Forest, Savanna.
Africa
east of the Nile has broken off
and formed East Africa (AKA Lemuria) and is covered in rain-forests. It
is called Lemuria now.
--Biomes: Savanna.
Madagascar
has drifted farther from Africa, and is still covered in rain forest.
The primary herbivores are lemurs, the primary carnivores are tenrecs,
which are very diverse, resembling hedgehogs, otters, weasels, rats,
etc...
