In general, so long as there is some solar heating beneath some level, there must be a net LW + convective heat flux upward at that level to balance it in equilibrium; convection tends to require some nonzero temperature decline with height, and a net upward LW flux requires either that the temperature declines with height on the scale of photon paths (from emission to absorption), or else requires at least a partial «veiw» of space, which can be blocked by increasing optical thickness above that level.

There are various reasons that this may occur, but the asymmetry is probably due to the fact that economic growth produces durable goods, such as cars and energy - intensive homes, and infrastructure, such as manufacturing facilities and transportation networks, that are not removed by economic decline and that continue to contribute to CO2 emissions even after growth is curtailed.
Taking account of their historic responsibility, as well as the need to secure climate justice for the world's poorest and most vulnerable communities, developed countries must commit to legally binding and ambitious emission reduction targets consistent with limiting global average surface warming to well below 1.5 degrees Celsius above preindustrial levels and long - term stabilization of atmospheric greenhouse gas concentrations at well below below 350 p.p.m., and that to achieve this the agreement at COP15 U.N.F.C.C.C. should include a goal of peaking global emissions by 2015 with a sharp decline thereafter towards a global reduction of 85 percent by 2050,
