From Peter Clack on X. It is kind of a big deal and yet another nail in the coffin for the #climatescam
”No sign of human fossil fuel in CO₂ emissions could be found in the past 40 years, according to a report by the National Technical University of Athens. The landmark study refutes almost every claim from the UN's global warming campaign. For example, there's been no change to the CO₂ signature since the Little Ice Age & human society was indistinguishable from all natural factors. Proxy data suggest the modern period doesn't differ from earlier centuries yet political agendas from the United Nations still promote the narrative that they 'own the science'.
The Little Ice Age lasted from the 16-19 centuries & immediately afterwards a warming period began which lasted until now. The causes were identical to the Medieval Warm Period in 1,000 AD, the Roman Climate Optimum in the first centuries BC & AD, the Minoan Climate Optimum in 1500 BC & other warming periods throughout the Holocene.
As a result of recent warming the biosphere expanded & became more productive, leading to increased CO₂ in the atmosphere & greening of the Earth.
The greenhouse effect on Earth has been stable in the last century due to the domination of water vapour in the atmosphere. Human CO₂ emissions played only a minor role in recent climate evolution & are hardly discernible in the observational data.
Overall, the paper confirms the major role of the carbon cycle in the biosphere & the non-discernible signature of humans”.
