OK!! Everybody pay attention!
Lesson for today:
1. The sun is 1,300,000 times as big as the earth.
2. The sun is a giant nuclear furnace that controls the climates of all its planets.
That’s not correct at all. The sun controls the amount of heat reaching the planets and the moons. The interaction of the sun’s heat with the atmosphere of the planets controls the climate. The moon is even more of a spec but it has no atmosphere to speak of so it is freezing.
You won’t defeat any global warming theory with this faulty line of reasoning. Rather you need to show that the amount of carbon dioxide at issue is insignificant in proportion to the overall atmosphere of the Earth, which it is. They try to resolve that problem by arguing a feedback effect with water vapor (because water vapor really does have a significant impact on heat capture and hence climate) but their model for this feedback effect is faulty. That’s what you need to argue, not how big the sun is.
Your 3rd sentence sums it up nicely.
With those who DO argue; NO additional data is going to dissuade them anyway!
