What will our planet Earth look like in around 100million years?

Presuming that the rate of global warming remains constant (not possible) and temperatures rise rapidly and cause ice caps to melt, sea levels to rise, blah blah blah, we might face an extinction of the human race and get wiped off the surface of the planet. However, our mother Earth has its own ways of recovering itself from seemingly irreparable damage, (presuming that it is still intact) it might return to its prime and pristine state as before we got all our machines out. Then, there might be a new sort of sentient life form that dominates the planet like we did and repeat our mistakes. That though, would takeat least 250 million years. Therefore, in 100 million years from now, the Earth would most likely look normal from outer space, but its seas and oceans and land are a desolate, bare and uninhabitable place, with only that select few being able to adapt and survive.
