I can easily imagine a couple of steeply rising trends on a decadal scale between now and 2100 (after all, we had 2 of those in the 20th century), but those still only gave us an overall temperature trend of around 1 degree or so.

(i) Were there any tipping points last century? If you want to argue that the two major rising trends over that period were tipping points of a sort, that's fine. But it means you'll have to explain WHY tipping points going forward will, of necessity, be many times greater than those experienced to date, in order to reach that 3 or 4 degrees "prophecy" by century's end.

(ii) On the other hand, if the tipping points are to be of a magnitude the likes of which we have not yet seen, that's also fine. But you'll have to explain HOW you arrive at those magnitudes.

Either way, it boils down to faith.
