You are correct. I have followed this subject closely for 30 years beginning in college when I bought the premise as a naive’ young person.
I remember the predictions and alarmist statements that never came to pass. On top of that, I became fascinated with the politics of the subject. The premise allows for centralized control of people and their activities. The funding is only given to those who promote the hypothesis.
The hypothesis has failed repeatedly, but they do not abandon it and say the “science is settled.” Real science is never settled.
AGW is a political idea wrapped in pseudoscience. The climate is constantly changing and history shows this to be true absent any influence from man.
And interesting enough back in the late 70’s and early 80’s when the new ice age was upon us many of the same scientist were calling for exactly the same measure to fight it. More centralized government, less freedom, higher taxes, reduced lifestyle. Funny how that works.
