As I have said before the green house effect and CO2 being a
greenhouse gas are both established fact. That you are prepared to go
on denying such facts makes you a laughing stock but doesn't alter
the said facts.

They are only established facts in your deluded imagination.

Now you are being a little stupid.

The greenhouse effect is well understood and an established fact.

That CO2 is a greenhouse gas is an established fact. It is not,
however the most abundant greenhouse "gas" in the atmosphere.

Climate change (both cooling and warming) is an established fact.

What hasn't been proven to any degree if certainty is:
- The magnitude of the contribution to warming (or cooling) of any of
the various atmospheric constituents that cause warming
- Is the warming/cooling caused by man or natural processes
- is there anything we can do about it
- is it even worth trying to do anything about it.
