But it does dent it by arguing through tree rings that we have had warmer periods in the last 2,000 years and that the relative positioning of the Sun and Earth through orbital variations are pretty important to our climate.
For me it highlights the problem of relying on proxies for global temperatures that let climate scientists claim they understand the temperatures of the past. The extrapolation necessary for limited proxy data interpretations to give me a lot of trust is just too much. So much so that I won't cheer and say this study of proxy temperatures is the one that finally got it right. But it does show the uncertainty.
Second, the highlighting of the effects of the big hot thing up in the sky on how warm our planet gets is surely the most important thing. We spend our time trying to figure out how much we puny mortals affect the climate that we neglect that this is a sun-centered solar system. Without the sun, our supposed efforts to heat the planet would quickly result in Earth becoming a block of ice on the surface.
But at least science continues in spite of the faith-based efforts we've had so far to get us to believe in
