So, given that everything observed is evidence of global warming,
the
thing to ask the proponents of this theory, is "what evidence
would be required to refute this theory?" When everything is
cited as evidence of a theory and nothing as evidence to dispute
it, then one needs to start questioning the person postulating the
theory.


Facts:

1. CO2 reflects infrared radiation.

2. The earth gives off infrared radiation.

3. When infrared radiation reflects back to earth, the global
temperature rises

4. Human produced CO2 can be distinguished from that produced by
other sources.

How?

Determining the carbon isotope ratios.

From your link, "CO2 produced from burning fossil fuels or burning
forests has quite a different isotopic composition from CO2 in the
atmosphere."

How, pray tell, is this capable of distinguishing between CO2 from
human-caused burning forests and CO2 produced by forest fires induced
by natural causes?

It isn't. But the major human produced CO2 comes from other fuels and is
likely several orders of magnitude more than forest fires.


Other questions to ask:
"Furthermore, the 13C/12C ratios begin to decline dramatically just as
the CO2 starts to increase -- around 1850 AD."
OK, when and where? Is this a local phenomena, or is this paper
making
the claim that starting around 1850, the entire world experienced this
increase?

No idea. Contact the author.



5. Humans are not necessarily the sole cause of global warming.
