What supersedes is that climate change is proven today
That is, in fact, scientifically impossible. The Earth is 5 billion years old. The temperature record is not yet 150 years old, and much of it was using imprecise instrumentation. Seeing as the changes are largely fractions of degrees over the span of the temperature record, it is absolutely impossible to claim that there is any evidence whatsoever of climate change happening
at all. We have, at best, a series of data sets that may imply short term changes, coupled with weakly correlative data sets for hypothesized causal factors.
On top of all of that, many of the data have been frequently altered and edited which makes them unreliable.
