Then we go to p3 where they claim "430" ppm of "greenhouse gases", which
they limit to only be "CO2". Then they use the 'conventional' figure of
"280ppm before the Industrial Revolution", for CO2! So now we know they
have padded the figure by some 70 - 80 ppm from the more accepted figure
of 350 - 360 ppm for CO2!

That's a lie. It's 360 now, man!

Hey, would you look at that! Lloyd got an answer CORRECT! Yes Lloyd,
it's about 360 ppm now, but the article claims that it's 430 ppm... So
Lloyd (and Orator) are correct, in stating that the article:

....has lied about the concentration, by claiming it is 430 ppm...


No, it says: "The current level or stock of greenhouse gases in the atmosphere
is equivalent to around 430 parts per million (ppm) CO2, compared with only
280ppm before the Industrial Revolution. These concentrations have already
caused the world to warm by more than half a degree Celsius and will lead to
at least a further half degree warming over the next few decades, because of
the inertia in the climate system."

All the GH gases are equivalent to CO2 of 430 ppm.

Did you even read it?


That is also what Orator stated... So Lloyd Parker actually agrees
with Orator's point...

280-300 is the accepted preindustrial. It never went to 360 in
human history.

You mean that _yesterday_ is not part of human history?

BTW, from a historical standpoint, we are at a very low atmospheric
CO2 concentration...

Not from a human civilization standpoint. What does it matter what happened
millions of years ago? Heck, why not go back to the big bang -- CO2 was zero
then!
