Let's be clear about what the IPCC actually says, so we can go on towards marginalizing ********MOD*******EDIT**************
From the IPCC report "Climate Change 2013: Physical Science Basis":
Is CO2 important?
Page 121: "Unequivocal evidence from in situ observations and ice core records shows that the atmospheric concentrations of important greenhouse gases such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) have increased over the last few centuries."
Does CO2 effect the climate?
Page 297: "Both anthropogenic climate change and anthropogenic ocean acidification are caused by increasing carbon dioxide concentrations in the atmosphere."
Does CO2 effect glacial cycles?
Page 400: "Such close linkages between CO2 concentration and climate variability are consistent with modelling results suggesting with high confidence that glacial–interglacial variations of CO2 and other GHGs explain a considerable fraction of glacial–interglacial climate variability in regions not directly affected by the NH continental ice sheets (Timmermann et al., 2009; Shakun et al., 2012)."
On Radiative Forcing, the capacity of a factor to influence the climate:
Page 56: "Forcing by CO2 is the largest single contributor to the total forcing during the Industrial Era and from 1980–2011."
Later, same page: "Carbon dioxide is the largest single contributor to historical RF from either the perspective of changes in the atmospheric concentration of CO2 or the impact of changes in net emissions of CO2."
