However, this in itself is not enough to define what level of warming is «dangerous,» especially since the projections of actual impacts for any level of warming are highly uncertain, and depend on further factors such as how quickly these levels are reached (so how long ecosystems and society have had to respond), and what other changes are associated with them (eg: carbon dioxide concentration, since this affects plant photosynthesis and water use efficiency, and ocean acidification).

I suppose that if all uncertainties are resolved in the direction of lower risk, we just might get away with BAU for the next few decades without a complete disaster (though continued sea level rise, ocean acidification and 2 degrees Celsius actually sound pretty risky to me, and the risk that there are other factors in play seems to be reinforced by paleo data on glacial - interglacial transitions).
