But what's the alternative? Ignoring the fact that our data is based on wrong assumptions? Act as if nothing has changed?
Sure, this is not good in the short time. But this is already a smoking gun for climate change deniers; if we were to put this under the rug for another decade, it would become a smoking nuke. And imagine the impact of that.
We know the assumptions are incorrect. Based on that, do we change course or not?
My understanding is that we are reducing emissions faster than predicted and will hit our politically agreed targets sooner than we expected. The political decision to change targets at any given point will be revisited based on what we understand at that time.
