> If the sun isn't the major driver of temperature then why is it colder at night?
They said that solar variability is not a major driver of climate change trends in the past century. Nowhere are they denying the sun plays a role in temperatures and weather.
> Also why isn't the effect of carbon dioxide cumulative? How can we have colder years ... shouldn't every year have to be warmer than the past?
Why would you expect it to be such a simple trend? We're talking about a non-linear dynamic system, not heating up food in a microwave.
> Somewhere, there are people who took the science out of science --- maybe to argue with religious people or something --- but this social consensus crap isn't how real science is done.
Yes, it's your friends in the denial industry, not those doing the actual research.
