Other planets besides Earth are warming too, which proves that humans can't be causing global warming.
We know changes in solar radiation are not causing other planets in our solar system to heat up because we can accurately measure the sun's output here on Earth, and it hasn't been increasing as other planets have warmed.
If anything, the lack of correlation between extraterrestrial planetary temperature changes and solar output changes emphasizes the importance of local changes in long-term planetary climate trends – providing further support to the idea that doubling atmospheric concentrations of greenhouse gases could result in significant climate change.
