I don't know the answer to that, but I can say that you and I are likely to be long gone before any explosion in biodiversity will occur. It won't happen for many tens of thousands of years (probably many millions).
People often seem to think the whole climate change is worrying about the earth and all the animal life. The earth will be fine, individual animals will hardly notice (they have much more immediate concerns most of the time, like being eaten).
It's humanity that is going to suffer, with the risk of many of our highly optimised systems becoming unsuited to task (think many cities and food production needing to shift, leading to starvation/conflict).
