I would guess that they are saying so called because most people who say 'climate change' assume that human-created c02 is the major driver of climate, when all of the detailed measurements taken since the forming of the IPCC have shown that the sensitivity is far lower. Each IPCC report has increased the confidence of the impact of human emissions, but lowered the effect. So the science says that we are more certain now than before, but that the sensitivity is much lower than understood before. This is great news but most people haven't realized that the scare stories of 10-15 years ago no longer apply. The term 'climate change' is pretty debased though, because it can mean anything from 'natural climate change' to 'Himalayan glaciers are going to melt in 20 years'. But the wording from this group is silly, there is no doubt.
