Just a quick post to point out an interesting paper from a MDPI Journal on atmospheric carbon dioxide and temperature. This article only came out in September and is very "controversial". I first heard about this idea about 15 years ago. Several academics though that the geological record seemed to demonstrate this but were not sure about the current situation. Alas, they also said they were too afraid to pursue this idea as it would take too much effort to defend.
The controversial bit can be summed up by this sentence in the abstract:
All evidence resulting from the analyses suggests a unidirectional, potentially causal link with T as the cause and [CO2] as the effect.
