The study below claim to finally prove the “Greenhouse Effect” …
They write in their introduction: “.. Direct measurements at the atmosphere are too strongly affected by convection, turbulence or scattering effects ..”?? (My Bold)
The set up ..
“Fig. 1 displays the experimental set-up that has proven particularly useful for our further investigations. Different to other experiments we use two plates in a closed housing ..”
That is all you need to know. They did not prove the “Greenhouse Effect”! The atmosphere is not a “closed housing” – the atmosphere is without walls!
Besides, that is the wrong way to do it. You have a theory, a hypothesis that say there’s a “Greenhouse Effect” – If you by experiments can’t disprove the hypothesis, the theory gets stronger and at some point it will become “a law.”
First step is to formulate a hypothesis, then a way to disprove the hypothesis. No surprise, that has never been done and all available proxy data, geological data, historical data and direct empirical measurements in the real world all tells us, there’s No “Greenhouse Effect” – No “Greenhouse Gases”!

Via No Trick Zone – By Kenneth Richard
German physicists claim to have experimentally demonstrated the greenhouse effect from greenhouse gases like CO2 and CH4 is a real phenomenon, but assess the climate sensitivity to a doubling of CO2 with feedbacks is “only ECS = 0.7°C … 5.4x lower than the mean value of CMIP6 with ECS = 3.78°C.”
“The derived forcing for CO2 is in quite good agreement with some theoretical studies in the literature, which to some degree is the result of calibrating the set-up to the spectral calculations, but independently it determines and also reproduces the whole progression as a function of the gas concentration. From this we deduce a basic equilibrium climate sensitivity (without feedbacks) of ECSB = 1.05°C. When additionally assuming a reduced wing absorption of the spectral lines due to a finite collision time of the molecules this further reduces the ECSB by 10% and, thus, is 20% smaller than recommended by CMIP6 with 1.22°C.”
