sun spot n solar r way over rated ... doubt it has much effect to be honest ... imo..

The data out there shows its minor, but everything I have seen does not combine other factors.  There is not a lot of data here and I think calling it over rated is premature.
More over this does not factor minor changes in Earth's orbit from year to year.  Considering the the ice ages are thought to be caused by earth's orbit extending further out from the sun, and the fact that they are regular occurrences it would back some sort of long term oscillation in earth's mean distance from the sun.

The space features are important like sunspot data.  The question becomes how much does the cooling influence of the sunspots compare to the warming influence of climate change/global warming.  I think the climate forcing is probably stronger than the solar, but that doesn't mean that we need to ignore the solar forcings as it may impact things like having an active northern jet stream which play a huge role in how our cool season goes down.

I disagree. We don't even fully understand solar and it's impact. For the first time the IPCC will have solar forcings in their model output. A good video on solar forcings and climate change https://youtu.be/rEWoPzaDmOA
