It's never too late to stop making things worse. And if we don't change our emissions it's going to get much worse.
I don't know, we could already be stuck in a positive feedback loop with no hope of reversing the trend until the pendulum swings back in another 10k years. That's the difficulty with climate science, there are so many variables and the system is so complex that analysis is extremely difficult.
EDIT: Just to be clear, I'm not saying we can't do ANY analysis or that we can't see the larger trends... just that the devil is in the details and we can't predict exactly what's going to happen or when.
There are large costs associated with changing what we're doing and in absence of being able to actually control the climate, those resources would be better spent on dealing with the outcome.
If you're standing downhill from an avalanche that you set off when you clapped your hands, making sure no one claps will not be your chief concern.
But we're definitely going to have to adapt because even if we stop it we've already changed things somewhat. The question is who, where, how much. And how much the adaptation will cost, and whether people can afford it, and and and.
How exactly is the climate worse today? The planet is greener than ever. Warming isn't intrinsically bad, as people are more likely to die from cold rather than heat.
Indeed it is.

Those are projections for the future. The implications of the GP was that the climate is worse today already. Where's the evidence for that? It's warmer, of course, but that doesn't imply "worse".
