0.08% = Human contribution of CO2 in the atmosphere.

If all humans on Earth went 'green' right this second it wouldn't stop
or even slow down global warming. Global warming is simply a cycle
that the Earth has experience about a dozen times BEFORE man even
existed.





No such cycle has been found yet. Do you have anything resembling
evidence?


A study of 700,000 years data was published in 1975. The cycles reported by
that study do not match the trends of the past thirty years. Although it
showed we should now be on a rising curve of global temperatures, the rise
started about twenty years early. It also "forecast" that the peak of
global temperatures achieved in the 1940s would not be reached again until
the 2030s. In fact, that maximum was passed around 1980 and we're now 0.5C
above the 40s peak.


What does this have to do with the CO2 human contribution to our
atmosphere?

Just asking is all.
