In other words: the

One issue is how to represent accurately the range of reasoned views on critical questions like the sensitivity of climate to greenhouse gases (basically, how
warm the world will get from a particular rise in gas concentrations); how
fast and far
seas will rise; how ecosystems will, or won't, respond.
First, there is still a lot of uncertainty about the extent and pace of

Second, as Gavin pointed out, the land - ocean temperature index tends to underestimate the truth because it's based on

As I've written before, while 20 years of intensifying inquiry has greatly reinforced confidence that humans are influencing climate in ways that could profoundly disrupt human and natural affairs, it has not substantially clarified climate outcomes that matter most: how
