Why the fixation on CO2
Just a thought, but has anybody ever considered the fact that perhaps CO2 has little (or nothing) to do with any recorded increase in temperature, and that perhaps it's all the extra HEAT we are releasing into the biosphere?
The Earth must have a certain capacity for heat dissipation into space, which under pre-industrialisation conditions was ***roughly*** the same as the energy received from the sun (less any stored in peat bogs etc.), hence the alleged stable temperature.
Energy from the sun ≈ Energy dissipated into space + Energy stored as future fossil fuel
In our current industrialised world, we are adding more heat energy to the system by burning fossil fuels, which represent a surplus of energy received by the Earth from the sun over millions of years.
Energy from the sun + Energy from burning fossil fuels > Energy dissipated into space + Energy stored as future fossil fuel (less storage than before)
And regardless of the efficiency of our fossil fuel power plants, even if they could achieve 100% efficiency, virtually all of that energy will end up as heat in the end, usually through inefficiencies elsewhere, although in some cases (electric heating, vehicle brakes) we intentionally dump it into the environment as heat.
Although this makes sense to me with fossil fuels, could somebody more knowledgeable confirm what effect the adoption of nuclear (fission or fusion) might have on the energy balance I have suggested?
