«greenhouse» gases in the atmosphere, since, as anybody but a climate change advocate nut knows, heat rises, most will then waft back harmlessly up
into space, as the earth, as all functions seek
equilibrium and homeostasis (those scientists believing that is a function of physiology and biology or entropy in a closed rather than open and single ended variant and changing
input system don't know what they are talking about) then shifts back
into balance, which is really what it is doing all along, since
These same parcels are large enough to be macroscopically in hydrostatic
equilibrium, supported by the well - defined pressure of their neighboring parcels of fluid and at rest, locked in place by the dynamic viscosity so that to move them one has to do work or otherwise
input external energy
into a parcel to destabilize them, overcoming «friction».
It's an appropriate definition for looking to the changes well past 2100 as Earth settles
into equilibrium again (by which I mean approximate radiative energy balance between solar
input and thermal emission to space).
