What we see clearly illustrated in the study at the link below is one of the fundamental problems of climate science: the natural variability is so large in Earth’s climate that teasing out a single climate variable (such as global climate sensitivity to atmospheric CO2 concentration) is statistically impossible. The signal is lost in the noise.
The natural variability of even the most significant variables (such as the atmospheric concentration of water vapor and clouds) is so large that the measurement of smaller variables (such as atmospheric CO2 concentration [~400 ppm]) cannot be distinguished from random noise in the measurement process itself. So far, there are no accurate and reproducible models of some of the most significant climate variables such as water vapor and clouds.
Therefore, it is a clear case of scientific fraud and criminal fraud for politicians to continue policies of paying out billions of taxpayer dollars, as well as a clear case of criminal fraud against any person or entity soliciting donations, since the claim that human-produced CO2 is pollution, or is an endangerment, is scientifically unproven. Moreover, the claim by alarmist that human-produced CO2 is contributing or triggering dangerous warming is even less provable since the atmospheric concentration of the human-contributed proportion of total CO2 [~40 ppm] and the warming or cooling that might be caused by that tiny amount cannot be accurately and reproducibly measured or modeled.
If anything, attorneys general, district attorneys, prosecutors and class action plaintiff attorneys should be arresting, impeaching and prosecuting those responsible for this ongoing fraud, which represents hundreds of billions of dollars in damages, possibly trillions of dollars. The people should be reimbursed. How long will you allow these people to yell fire in the theater before you demand that they stop and punish them?
