You are quite correct that efficiency has improved and many forms of pollution are down in abdolute terms as well. However all these smoke screen use of statistics ignore the fundamental data indicating CO2 levels have risen along with industrial output.
So:
Absorption in the ocean IS NOT compensating fully for increased emmisions.
The fact that CO2 is naturally produced and removed by geochemical forces DOES NOT imply that man can not disturb the established natural equilibrium or more likely semi-equilibrium.
And I's really like to see a reputable scientific source indicating human produced CO2 is insignificant compared to volcanic eruptions. I've often heard this claims on BBs, but not noticed it in reputable scientific sources (ie not Rush Limbough). That claim simply does not square with rising CO2 levels.
