forcings

As a result, the major climate "forcings" - changes in the radiation balance initiated by human activities - are much better understood.

But they also say that the Earth’s temperature system is dominated by positive feedback, meaning that very very small changes in forcings are magnified many fold in to large temperature changes.

Boundary conditions are more specifically referred to as forcings, because they force the sea ice to change in a certain way, based on influences from the ocean and atmosphere.

The present book is an occasionally breezy, but more often sobering assessment of the current projections of global warming, Hansen's own role in bringing it to governmental attention (he describes his meetings with Dick Cheney's Task Force), and an overview of the technical components of climatology -- the various climate "forcings" that are expressed in watts per square meter.

So I'm still left puzzled as to why, when yet again (and again and yet again) the relationship between CO2 and temperature is shown to be non-monotonic and non-linear (as it cannot otherwise be in a very heterogeneous medium such as the surface and atmosphere of the Earth), that the discussion is almost entirely in terms of the 'forcings'.

The IPCC models are sensitivity studies because all they use are "forcings", pre-selected variables of the data that will fit with what they want to find.

To understand why this is true, you have to know that given the base CO2 level as that of 1880, and that the forcings are a logarithmic function of the CO2 concentration i.e. each doubling only produces a linear increase in forcing so the fact that we’ve added about 40% to the initial CO2 concentration means we’ve added about 50% of the total temperature increase from doubling CO2 concentration.

The relationship is poor, hence the need to add "forcings" by other atmospheric components.
