Probably not much, is the short answer.

A recent UN report claims that “up to a million species of plants and animals are declining at a rate previously unseen in human history.” Well, that’s hardly surprising. It’s being blamed on climate change. Again, hardly surprising. “Human history” barely registers an eyeblink on the scale of the Earth’s history. Mass extinctions, however, are common occurences.
While there have been lesser extinction events (close of the last Ice Age for eg.), To the best of our knowledge there have been five Mass Extinction Events at fairly regular intervals in the Earth’s past. Humanity wasn’t around to witness them.
Many scientists believe the sixth Mass Extinction is actually in progress right now. Climate played a big factor in the previous five, (despite a deficit of handy humans to blame) along with other mechanisms. Currently the weakening of the Earth’s magnetosphere is clearly a factor. Exactly how much human activity currently contributes to climate change is an uncertain and contentious issue, despite the UN and IPCC propaganda to the contrary. Perhaps a more valid issue might be: Are we ourselves part of Nature’s schedule for extinction this time around?
Here’s a list of “The Big Five” ELE’s:
End Ordovician, 444 million years ago, 86% of species lost
Late Devonian, 375 million years ago, 75% of species lost
End Permian, 251 million years ago, 96% of species lost
End Triassic, 200 million years ago, 80% of species lost
End Cretaceous, 66 million years ago, 76% of all species lost
Makes the UN alarmism seem rather insignificant. While it’s sad that we may lose species to the Earth’s natural changes, there isn’t much humanity can do to halt Nature’s progress (except by geo-engineering, the consequences of which could be far more catastrophic than the natural process itself!).
This is an entirely different matter than extinction and endangerment due to poaching, unsustainable land use, destruction of environment etc, which IS caused by human mismanagement and CAN be addressed by the UN and the big corporations, if they can look up from signing climate accords and start taking some real responsibility, rather than blaming carbon!
