somebody should do a paper and see if there is significant convective heat transfer to the north that allows for easier radiative heat energy lost to space. could be a significant negative feedback.

No, I see two strong positive feedbacks if we re-distribute heat from tropics to poles:

1. 4th power of temperature dependence of IR radiation. Tropics radiate at ~300K, poles at ~250K.

- so 1/2 x 300^4 for tropics + 1/2 x 250^4 poles = total current IR outgoing

- if we switch to a completely "equable climate" where tropics and poles are evened out by super efficient heat transport, then the new average temperature for both is 275

- 275^4 is about 5% less than 1/2 x 300^4 + 1/2 x 250^4

- therefore about 240 W/m^2 x 95% = 228 W/m^2 = 12 W/m^2 forcing. That's huge.

2. replacing cold dry polar air with warm wet air would increase net GHG forcing, too. I don't know how to calculate that one, though.
