I’m not a chemist or scientist but I did get an MS degree in Computer Science last century and I worked at NOAA/NWS and I stayed at a holiday in express last night, so I would assume a closed system also.
I could tell stories about how the satellite data - especially sea surface temperature - is quote “calibrated” that would add further doubt to AGW theory. But I value my time left on this planet, so I don’t care to visit Civil War Parks unless I’m still breathing so I’ll keep my mouth shut.
A FOIA request however for the algorithm ( hint hint wink wink, nod nod say no more, say no more .... ) would yield interesting insights into the state of the “Science” and reveal my doubts for at least one “major” data sets validity.
The alaemists are doubling down the more the hoax is being exposed. They are desperate.
