Nope. You're confused. Climate change is neutralized by allowing the ice caps to melt which will cool the atmospheric affects of centuries of industrialism.
Nuclear will never be an option, because you just can't get free energy out of the universe. Nuclear energy is essentially an attempt to get free energy out of the creation of the universe that NO SCIENTIST UNDERSTANDS. Do you get it?
If the universe is a 6 dimensional Kalabi-Yau manifold, you don't know if all those galaxies are really just re-reflections of ONE galaxy in a hall of mirrors. The 3d view of space and the idea that there are billions of other suns like ours could be a complete clusterfuck of your own warped and simple-minded model of reality which you never explained.
Please, science hasn't even explained why isotopes exist that are radioactive while others are not. THEY DON'T KNOW. But, you, grasshopper, know that energy isn't free AND you know that cheap energy to this wasteland of civilization is the WORST idea ever.
Try free love rather than free energy. But this time, with Truth. Do you have enough of it?
