I don't think I even need to do the math on this, to demonstrate that our total energy usage is many orders of magnitude smaller than what would be required to cause the problem you're discussing. Solar is great, and growing fast, but for fairly obvious reasons works better as part of a multifaceted solution than as a single source.
