is it too late to curb global warming?

Not yet.  But it will be before we get around to doing anything about it.  I don't think human beings have evolved quite enough yet to have a large capacity to plan ahead very far.  When it comes down even to our own survival, we're still very short-sighted, reactive and, worst of all, combative with one another.  And that's not going to change quickly enough to allow us to undertake the large-scale efforts that would be necessary to avert a continuation down the road we have put ourselves on where global warming is concerned.
