My take is that the tug of war over what's causing today's telegenic heat waves, floods, tempests — and even Arctic sea - ice retreats — distracts from the high confidence scientists have in the long - term (but less sexy) picture: that more CO2 will lead to centuries of climate and coastal changes with big consequences for a growing human population (for better and worse in the short run, and likely mostly for the worse in the long run).

«What is generally required [for proving solar forcing of climate change] is a consistent signal over a number of cycles (either the 11 year sunspot cycle or more long term variations), similar effects if the timeseries are split, and sufficient true degrees of freedom that the connection is significant and that it explains a non-negligible fraction of the variance.»

Heat capacity that is «used» over a longer period of time (penetration of temperature change through the depths of the ocean and up to regions of upwelling) would leave a more persistent residual imbalance, but the effect would only just stall the full change to equilibrium climate, not change the long term equilibrium sensitivity.)

There are as many different definitions for that term, and for «climate change,» as there are factions in the national and global disputes over this issue.
