Popular claims that changes in carbon dioxide (CO2) cause current or distant past temperature changes are “based on imagination and climate models full of assumptions.” [emphasis, links added]
A comprehensive new study details stochastic estimates of the sequence of carbon dioxide changes and temperature changes since the 1950s, over the past 2000 years (AD), and over the past 541 million years.
Robust conclusions are the direction of causation – Understand what leads to leading and influencing behind – It is clearly shown that temperature changes lead and CO2 changes lag on annual, decadal and centennial/millennium scales.
in other words, “Reverse direction of causation [CO2]→T should be excluded.
Therefore, the claim that CO2 increases drive temperature changes is just a “narrative” because The claim that humans are responsible for the climate change we are seeing through emissions from the burning of fossil fuels can be considered a “non-scientific question.”
The authors have published a series of peer-reviewed scientific papers supporting the same T→CO2 conclusion (Koutsoyiannis et al., 2022, Kousouyanis et al., 2020, Koutsoyiannis et al., 2023, Kousouyanis, 2024, Kousouyanis, 2024) just in the last few years.
Because these papers so sharply challenge the prevailing narrative of anthropogenic global warming (AGW), Understandably, Dr. Kousouyanis is met with almost vitriolic hostility from AGW supporters.
This includes comments from peer reviewers. So, in an effort to increase transparency, he made public the peer reviewers' comments on this latest paper. Here are links to those comments:
