- On a global scale, the direct heating from combustion of fossil fuels
- (as opposed to the indirect heating from altered atmospheric radiative
- properties), is insignificant, perhaps .01% of global insolation.
- Natural variations in the solar constant are an order of magnitude
- larger. Changes in Earth's albedo from alterations in climate or
- deforestation are also, I would think, much larger.
