'zero sum game' Thermalization spreads the absorbed photon energy so rapidly throughout the thousands of surrounding molecules so rapidly that there is virtually undetectable heating rate (increase in T2) and the energy returned to the GH molecule is tiny and will take a long time to statistically accumulate enough energy in any given GH molecule to re-emit ...

There are several interacting effects. And for global warming, we need to look at the whole earth. First effect: putting the panels up may change the albedo - the reflectivity - of the surface. That will increase the amount of energy absorbed by the earth, rather than reflected into space. The effect would be a miniscule increase in heating. Second ...

The energy budget of the earth is predominantly dependent on the balance between radiation coming from the sun ( there exists internal energy from the magma in the earth but it is a small percentage of the energy budget) and radiated energy from the earth back to space according to a modified black body radiation. There is a secondary energy budget that ...

Solar panels are dark (they have to absorb light) and they do decrease the Earth's albedo, i.e. they make the planet locally darker. This means that locally they will cause slight additional heating. Part of the energy that a panel absorbs gets converted into electrical energy, which can be transferred off-site, i.e. removal of energy actually cools the ...
