Although the sun provides nearly all the energy needed to warm the planet, its contribution to climate change remains widely questioned. Many empirically based studies claim that it has a significant effect on climate, while others (often based on computer global climate simulations) claim that it has a small effect.
That’s how you do science, you have an opinion on something and then you find the data, that proves your point and ignore everything else. No mention of why the hell the sun would completely change its impact on global temperatures in a matter of one century, when it had only a small impact for millenia.
