Climate scientists: concept of net zero is a dangerous trap

[NNadir]

4. The thermodynamics of carbon dioxide reduction require that all the energy...

...obtained from putting it there be put back into it, plus all of the entropy, both of mixing and heat generation.

In short, this means that to effectively remove carbon dioxide in an irreversible way - I'm not talking giant CO2 dumps - we have to reproduce, without dangerous fossil fuels, all of the energy ever produced by burning fossil fuels from the first lump of coal to the last - plus all the entropy.

Thanks for being aware.

Jim Hansen, by the way, has forcefully endorsed the only sustainable form of energy production there is, nuclear energy.
