And then there's this: New Peer Reviewed Study: CO2 has Zero Impact on Climate Change - The HighWire

A powerful peer-reviewed scientific study delivers substantial evidence that carbon dioxide (CO2) emissions in the atmosphere have zero impact on the Earth’s global temperatures. The study concludes that even though most publications attempt to depict a catastrophic future for our planet due to an increase in CO2, there is serious doubt that this is, in fact, the case. Instead, the study authors deduced that their research unequivocally means that the officially presented narrative that human activity is causing a detrimental CO2 increase on Earth’s climate is merely a hypothesis rather than a substantiated reality.
