One example that I wasn't previously aware of, were the climate events of 536 AD — «dry fogs», crop failures, «dim suns» and yellow snow etc. — features consistent with a large volcanic eruption, possibly near the site of Krakatoa — and which correlates with evidence of a sulphate peak in the North GRIP ice core at the same time.

The long timescales (even ignoring the «Earth system» responses like ice sheets and vegetation) are not easy to get at in the instrumental record or by studying «abrupt forcing» events like volcanic eruptions.

(For those «coming in in the middle» — assuming any such are still reading — this subthread began with a link I provided discussing the vulnerability our complex society bears WRT to very large volcanic eruptions, in the context of the robustness of some Stone Age populations who «thrived» during the event — albeit at a considerable distance!)

Volcanic events and ENSO are natural thermodynamic cycles, and at their conclusion the net heat exchanged with surface is zero.

Some commentators have responded to those questions with bewilderment and — at least partial — resignation, as if rightwing populism and hatred are unavoidable socio - political events, much like volcanic eruptions or earthquakes.

We do not know enough to determine under what circumstance CO2 is a forcing or a feedback relative to temperature sometimes it maybe both sometimes over large areas it may even be a coolant e.g. if you think it is the main driver (which I don't) you would have to say it acted as a coolant for several thousand years from the Holocene climate optimum to the LIA — see Fig 6 in the last post at http://climatesense-norpag.blogspot.com I quoted the end Permian Siberian traps as a possible example of CO2 as a forcing but even here CO2 was rising rapidly before the volcanic event.

While its not entirely fair to remove a modeled event from the record, it's also not at all fair to compare skill over such a short time frame, when volcanic and other effectively random events can skew either path (observational or modeled) so greatly.
