This has been known to those of us who actually had real classes in physics & math. There are myriad reasons, but I’ll leave just one. Find a chart of CO2 concentrations during the past 4 billion years or so. (Yes, they are available.) Note that the present CO2 concentration is only barely above the lowest it has even been in the entire earth history. Also note that the ice ages occurred during the highest concentrations of this supposedly dangerous gas.
Yup, climate changes. However, there’s pretty much nothing we can do about it. Except find and take care of idiot leftists who want us to sacrifice, but not them.
If man made climate change was real and a threat, our elites would ban private jet travel and conspicuous consumption mansions. Also, there are plenty of crony capitalist companies making millions off the scam.
