More than 95 % of the 5 yr running mean of the surface temperature change since 1850 can be replicated by an integration of the sunspot data (as a proxy for ocean heat content), departing from the average value over the period of the sunspot record (~ 40SSN), plus the superimposition of a ~ 60 yr sinusoid representing the observed oceanic oscillations.

There is no evidence that anything unusual happened from the added CO2 in the second half of the 20th century... and the average temperature has barely changed so far in the 21st century, especially if you ignore the 2015 / 2016 El Nino peak, which has nothing to do with CO2.

I also used my implementation to break up a quick land response from a slow ocean response to see if the change in sign of the derived temperature derivative coming at a place where it is not intersecting the instantaneous temperature might be explained by the derived temperature being an average.

Starting from an old equilbrium, a change in radiative forcing results in a radiative imbalance, which results in energy accumulation or depletion, which causes a temperature response that approahes equilibrium when the remaining imbalance approaches zero — thus the equilibrium climatic response, in the global - time average (for a time period long enough to characterize the climatic state, including externally imposed cycles (day, year) and internal variability), causes an opposite change in radiative fluxes (via Planck function)(plus convective fluxes, etc, where they occur) equal in magnitude to the sum of the (externally) imposed forcing plus any «forcings» caused by non-Planck feedbacks (in particular, climate - dependent changes in optical properties, + etc.).)

So the intensity of radiation (at some frequency and polarization) changes over distance, such that, in the direction the intensity is going, it is always approaching the blackbody value (Planck function) for the local temperature; it approaches this quickly if the absorption cross section density is high; if the cross section density is very high and the temperature doesn't vary much over distance, the intensity may be nearly equal to the Planck function for that location; otherwise its value is a weighted average of the Planck function of local temperature extending back over the path in the direction it came from.

... Conclusions Since 1950, global average temperature anomalies have been driven firstly, from 1950 to 1987, by a sustained shift in ENSO conditions, by reductions in total cloud cover (1987 to late 1990s) and then a shift from low cloud to mid and high - level cloud, with both changes in cloud cover being very widespread.
