There is a vast difference between a mere conjecture
unsupported by any facts like yours above, and a
theory supported by facts like that at the top of this thread.

This is what science is all about Roger. I don't see how the facts
support your theory and I was merely pointing out an alternative
hypothesis. I don't have access to this kind of data, but maybe someone
else reading this thread does. Science is about adjusting your
hypothesis to fit the facts, not selectively using the facts to support
your hypothesis. That's called pseudoscience. Do you have anything to
support your hypothesis that CO2 traps heat more effectively during the
night than during the day?
