So the 3.7 W m - 2 calculation for global radiative forcing could be refined perhaps by an improved experimental design (not necessarily by improved radiative transfer models) running RT models at each grid cell over the globe, over the diurnal cycle and the annual cycle for say 30 years, for the two different CO2 concentrations, such a detailed calculation would refine the 3.7 value.

We need to be careful focussing upon «trends» — it can lead to serious errors of context — and this underlies the entire «global warming» thesis which relies upon computer models with entirely false (i.e. non-natural) notions of an equilibrium starting point and calculations of trend — this conveniently ignores cycles, and it has to because a) there are several non-orbital cycles in motion (8 - 10 yr, 11, 22, 60, 70, 80, 400 and 1000 - 1500) depending on ocean basic, hemisphere and global view — all interacting via «teleconnection» of those ocean basins, some clearly timed by solar cycles, some peaking together; b) because the cycles are not exact, you can not tell in any one decade where you are in the longer cycles.

Combining Zwally's calculations with recent evidence from Greenland, sea level models driven by global warming should reveal a decreasing rate of sea level rise.

Some examples from energy balance model calculations indicate that: (1) solar variability has a near - global response, with the amplitude of response slightly larger over land; (2) volcanism has a proportionately larger amplitude of response over land than over ocean; and (3) the most oft - cited mode of internal variability, changes in the North Atlantic thermohaline circulation, has a hemispheric asymmetry in response.
