The problem with your post is it isn't even wrong. Just irrelevant. Our sun is a variable star. But is nowhere near variable enough to account for the climate changes in the geological record. Google snowball earth sometime. Greenhouse gases act as an amplifier of changes in in isolation. Not to mention changes in albedo, covering and exposing carbonaceous material, creation and drying of bogs, etc.

Our planet has a lot of mechanisms that take pretty small changes and amplifies them to create big changes in climate. We have been mining and burning billions of tons of fossil carbon in the form of coal alone a year for decades. Lesser amounts for centuries. We have significantly increased the amount of CO2, methane, soot particulates, water vapor and other things in our atmosphere. And those are triggering other mechanisms, like open water in the Arctic, which are amplifying those changes. Likewise, the increasing temperatures are causing bogs to dry up and permafrost to melt. Both of those then release their methane and expose their carbon to oxidation. Ocean bottom waters are warming. That means they hold less dissolved gasses and opens the possibility of the clathrates becoming unstable and releasing their methane. And there is a lot of both at the bottom of the oceans.

So your thinking in this, like many subjects is simplistic, ill-informed and superficial.
