1 When designing the Norwegian Earth System Model (NorESM), instead of starting from scratch, the modeling groups took the atmosphere model (called CAM) from the climate model called CESM, an ocean model originating from the MICOM model and the carbon cycle model HAMOCC from GerModel (NorESM), instead of starting from scratch, the modeling groups took the atmosphere model (called CAM) from the climate model called CESM, an ocean model originating from the MICOM model and the carbon cycle model HAMOCC from Germodel (called CAM) from the climate model called CESM, an ocean model originating from the MICOM model and the carbon cycle model HAMOCC from Germodel called CESM, an ocean model originating from the MICOM model and the carbon cycle model HAMOCC from Germodel originating from the MICOM model and the carbon cycle model HAMOCC from Germodel and the carbon cycle model HAMOCC from Germodel HAMOCC from Germany.

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.

For new technologies the ETA team often starts with a life - cycle energy, water, or materials analysis to understand the technology's impacts when scaled up, and then uses other models as needed, such as an atmospheric chemistry model or energy system model.

The reason because those longer cycles have not been included in the present model is because their amplitude is not certain given to the fact that the temperature records start in 1850.

It's plausible that this lag could take an entire solar cycle or that it started 2 decades ago and is one reason that the global climate model projections have all been too warm (since they do not have equations to represent this dynamic).
