@parados,
Quote:Since you agree that the laws of thermodynamics do apply to the Earth then explain how the energy gain and loss doesn't apply when calculating temperature of the earth as a whole.
Do you know how must the earth mass as a whole?
Try 5.97 x 10^24 kg........
You do not change that mass temperate in any measurable manner in thousands of years without having the sun going nova and the sun is too small to do go nova.
Hell the earth center is at thousands of degrees with an melted iron core and decouple to a large degree, thank god, by the insulation properties of the earth crust and mantle from us.
When talking about the earth temperature you break the problem up to the temperatures of the parts of the earth biosphere not the whole earth!!!!!!
The earth is not a simple black body that you can do the calculation you are thinking of.
The temperature of the top of the atmosphere is not the temperature at ground level and the temperature of the ground is not the same as the lower atmosphere and the temperature of the oceans are not the same and......
You can not treat the earth as a whole in the manner you wish to treat it.period.
Only a small uniform object could be so treated.
