OK, Ludwig says the temperature data used to calculate AGW goes back 300 years. The Earth is 4.5 billion years old.

So using data taken from .000006667% of the age of the earth we can confidently calculate the normal temperature of the earth and if its off by a fraction of a degree then it’s caused by humans.

This is why I am a skeptic. It doesn’t make sense.

Well actually we have geological data that goes back billions of years. However, if you actually read the science you would not need the whole Earth to look at for it’s whole history. If you understand that CO2 is a GHG and there is a lot more of it, the warming follows. Why do you not get that? What is so hard to understand?
