possibly necessary, some areas certainly. one problem is what happens next, poor politically driven decisions. policies such as mandating vegtable oils (leading to deforestation to grow palm oil) and wood chip imported from 3000 miles rather than local gas. potential market solutions are...
not refering to anything specfic, was giving background to the idea. its not new maybe 20 years or so. and there's no denying the sun is the primary factor in climate, so why wouldnt variance have some impact?
the suggestion is the solar output is may have more affect on world temperatures than local emissions. early models and studies didnt include solar input or applied a simple constant, when its known to change. as the primary source of all energy in the atmosphere, it has more than a limited effect.
instead we're driving to carbon neutral targets requiring twice as much electrical power than we currently use. not going to work without a lot of nuclear construction starting very soon.
so we should give up worrying about it? build nuclear to save the world isnt going to sell well to the rest of the eco-brigade. heard the predictions 10, 15, 20 years ago, how many are accurate?
