If the answer lies in one or more of the many known & unknown variables that have nothing to do with CC, then how do we know it is due primarily to AGW as is being propounded, and how can we have confidence in the accuracy of the measurements?

Trend versus variation.

This equates to the equivalent of 58 000 000 000 km's driven every single day of the year.



That's just one of the factors you queried about earlier.

You really have to read what you post. That test is performed.

So we endure the disruptions & hardships of reducing fossil fuel consumption, but it's all for naught on account of we're still here & breathing?

A short explanation for you.

Nope.

Trend depends on the interval between the start and end dates.

Fitzhenry omitted 30 years of available data.

OK, the interval between the start & end dates if you'd like. But the start & end dates are necessarily dispositive. No matter, since there doesn't appear to be much controversy over my hypothetical upward trend line going back to the last glaciation.

So how about my question on variation -- since human-caused warming (according to many) became a factor? Where is it in the NOAA or Denison datasets for attributing sea level rise to AGW off Australia? Just use the NOAA data if it better suits. We don't need to continue bashing Fitzhenry.

Are you suggesting that exhaust emission CO2 behaves differently to breathed out CO2? Is this what you are suggesting?

Doesn't seem to account for the additional 6.3B people Reef cited. Or better yet perhaps, however many additional people we've added since we started burning large amounts of fossil fuels. If the theory is that fossil fuels tipped the balance beyond what the earth could absorb & sequester, then why not all those additional people?

Of course it does not. But the CO2 we exhale we remove from the system again by eating vegetables and meat.

Cars do not eat, at least not mine.

That is what is the evidence says.

From newhaul's link

Quote:
In particular, the mass 47 anomaly (Δ47) can distinguish between CO2 produced by high temperature combustion processes vs. low temperature respiratory processes.

Because the the analysis of the increased CO2 points to the burning of fossil fuels.
