"gases" is plural, doofus.
That in no way addresses the challenge to the assertion that CO2 is a
"prototypical greenhouse gas, whose characteristics explain and define
all other GHGs..."
You've put this in quotes as though somebody had said it, but searching
for the phrase suggests otherwise.
CO2 is greenhouse gas. It doesn't explain and define others however,
but given that the effect of each gas can be measured and characterised,
any given amount of another gas can have an effect which can be
expressed as an amount of CO2 that would have the same effect.
-- which is what your "equivalence" implies...
In your dreams I think...
It is history and it shows that high levels of CO2 does not correlate to
"human caused" as your dogma recites.
Nobody has ever claimed humans caused the CO2 to go up millions of years ago,
but we are the cause today.
So what?... Did 6000 ppm exterminate all life on Earth? Oh, that's
right...all life _was_ exterminated, which is why you are NOT arguing
with me now (since all life on Earth died)...
Doesn't mean that modern life / agriculture / ecosystems etc would cope
well.
