The average ground temperature of the Earth is impossible to measure since most of the Earth is ocean...So this average ground temperature is a fiction.

The marketplace judges technologies by their practical effectiveness, by whether they succeed or fail to do the job they are designed to do.

I am hoping that the scientists and politicians who have been blindly demonizing carbon dioxide for 37 years will one day open their eyes and look at the evidence.

The fundamental reason why carbon dioxide in the atmosphere is critically important to biology is that there is so little of it. A field of corn growing in full sunlight in the middle of the day uses up all the carbon dioxide within a meter of the ground in about five minutes. If the air were not constantly stirred by convection currents and winds, the corn would stop growing.

A model is such a fascinating toy that you fall in love with your creation.
