I don't think anyone denies that the sun matters for climate, but the question is whether the variability of the sun in recent history has had the impact that we project from greenhouse gases over the next 100 — and there, I think, a majority of your «AGW» ers» would think the evidence suggests that changes in human forcing will likely be several times (at least) larger than any solar variability we've seen in a thousand years or more.

A larger mystery than either missing carbon or the influence of clouds / water vapor on climate change models is why the physical and life science community and the (in theory) science - based climate change advocates have not taken the time to adequately consult the evidence or experts (albeit exceptions certainly do exist) on communication about environmental issues, risk, or environmental and health literacy.

In other words, a DO event (brought on this time by anthropogenic global warming) should be seen as larger and more rapid climate change than anthropogenic global warming.

As we discussed at the time, those results were used to conclude that the Earth System Sensitivity (the total response to a doubling of CO2 after the short and long - term feedbacks have kicked in) was around 9ºC — much larger than any previous estimate (which is ~ 4.5 ºC)-- and inferred that the committed climate change with constant concentrations was 3 - 7ºC (again much larger than any other estimate — most are around 0.5 - 1ºC).

The IPCC range, on the other hand, encompasses the overall uncertainty across a very large number of studies, using different methods all with their own potential biases and problems (e.g., resulting from biases in proxy data used as constraints on past temperature changes, etc.) There is a number of single studies on climate sensitivity that have statistical uncertainties as small as Cox et al., yet different best estimates — some higher than the classic 3 °C, some lower.
