Recently Alan Jones was subject to an adverse finding by ACMA.
The finding was that Jones had not adequately presented the facts about how
much CO2 Australia contributes to the atmospheric total.
What ACMA found was that Jones’s statement about the % of
CO2 produced by Australia was his opinion and not, as implied when he made it, a
scientific fact.
Jones’s opinion was that Australia produced 1/100,000th
of the CO2 in the atmosphere. Jones also failed to produce any research to
substantiate this opinion presented as ‘scientific fact’.
That is Jones’s error; not that his estimation of the CO2
contributed by Australia to the atmospheric bulk total of CO2 was necessarily
wrong but that he presented it as a scientific fact.
The complainant to ACMA was not identified but there was a
flurry of pro-AGW disapproval of Jones’s comments at the time from the usual
subjects like Karoly
who has a record of getting the sums wrong in a way far more egregious than
Jones’s ‘error’.
Apparently, according to Karoly, the correct contribution of
Australia to the total atmospheric concentration of CO2 is 0.45%.
According to Walter
Stark, “Karoly’s figure may be derived by assuming that the purported rise of
CO2 from the 280 ppm preindustrial level to current levels is due to
anthropogenic emissions. This then puts the anthropogenic contribution at about
30% of current levels and Australia’s 1.5% share of global anthropogenic
emissions then becomes responsible for about 0.45 % of total atmospheric CO2.”
Professor Murry Salby’s work makes that assumption that
anthropogenic CO2 is responsible for the increase in CO2 problematic. But even
if we allow that assumption Karoly’s figure of 0.45% is doubtful.
The bulk
atmospheric CO2 is increasing by about 1.5ppm PA or about 4Gt; then there is
the annual flux which is the movements into and out of the atmosphere which are
described here.
Currently
the atmospheric bulk is about 3000Gt; the annual flux is 218.2Gt [from Figure
7.3, AR4].
The amount
of human sourced CO2, ACO2, in that annual flux is 8Gt, or about 3.67% of the
FLUX.
How much of
that flux actually stays in the air and adds to the atmospheric bulk? The
answer is given by the US Department of Energy [DOE]; see Table 3 on page 22 of the PDF.
From this
we can see that 98.5% of ALL annual emissions of CO2/ACO2 are reabsorbed and
about 1.5% of the flux or about 4Gt is added to the atmospheric bulk.
In 2009
Australia was 16th of the world’s nations CO2 emitters, emitting 374 million tonnes or about
1.28% of ACO2.
So, there
are all the facts; who is closer to the truth; Jones or Karoly?
1.5% of all
CO2, both natural and ACO2, is retained annually to add to the atmospheric
bulk.
Of that
1.5% addition, annually, the ACO2 component is 3.67%; so ALL of nations’
contributions is 3.67/100 x 1.5/100 = 0.000552.
Australia’s
annual emissions are 1.28% of the global ACO2; so 0.000552 x 1.28/100 = far
less than what Karoly said and even less than what Jones said.
So, both
Jones and Karoly are wrong but Jones is closer to the truth.
This of
course hasn’t stopped more of the usual subjects, like the ubiquitous John Byatt,
from congratulating the finding against Jones and arguing against any
revelation that their precious AGW is not happening.
It is
evident that nothing will convince the believers of AGW that their belief is
wrong. In this respect they are like religious fundamentalists. Australia
allows for freedom of religion. The question is should the government
financially support the religion of AGW and strive to make it the official
Australian religion in contradiction of the Constitutional safeguards?
Scientific debate should never be decided by consensus. It should be “decided” by empirical evidence that validates, or otherwise, the hypothesis in question.
ReplyDeleteJoseph Postma’s new paper (22 October 2012) looks for empirical evidence of a GHE, and finds none. He puts forward cogent arguments as to why this lack of evidence is to be expected. All should read this ground-breaking work, which also cites my paper (March 2012) - see pp 47-49:

Ocean emit 332Gts absorb 450Gts

total left in atmosphere equals 23Gts minus 12Gts
equals 11Gts (all human)
Australian contribution 2011
total human Mts 30,398,420
Australia Mts 417,680
australian % = 1.37
total remaining in atmosphere 2011 = 43% of 30,398,420

So
Australian contribution to what remained in atmosphere must also be = 1.37%
Hmmmm

DeleteJohn Byatt your figures do not match the official source of emissions and sinks from AR4, Figure 7.3:
ReplyDeletehttp://www.ipcc.ch/publications_and_data/ar4/wg1/en/figure-7-3.html
Please indicate the source of your amounts and why they should be preferred to the IPCC quantities.
In addition do you seriously query my calculations about the annual flux and if so indicate how and why?
And Geoff may tolerate your smart-alec comments, “Facts never make it” – but you’ll get zero tolerance from me.

In Figure 7.3 the natural or unperturbed exchanges (estimated to be those prior to 1750) among oceans, atmosphere and land are shown by the black arrows. The gross natural fluxes between the terrestrial biosphere and the atmosphere and between the oceans and the atmosphere are (circa 1995) about 120 and 90 GtC yr–1, respectively. Just under 1 GtC yr–1 of carbon is transported from the land to the oceans via rivers either dissolved or as suspended particles (e.g., Richey, 2004). While these fluxes vary from year to year, they are approximately in balance when averaged over longer time periods. Additional small natural fluxes that are important on longer geological time scales include conversion of labile organic matter from terrestrial plants into inert organic carbon in soils, rock weathering and sediment accumulation (‘reverse weathering’), and release from volcanic activity. The net fluxes in the 10 kyr prior to 1750, when averaged over decades or longer, are assumed to have been less than about 0.1 GtC yr–1. For more background on the carbon cycle, see Prentice et al. (2001), Field and Raupach (2004) and Sarmiento and Gruber (2006).

DeleteJohn Byatt’s amounts from Figure 7.3 are incorrect; the total emissions, both natural and anthropogenic, are 218.2Gt; the anthropogenic component of that 218.2Gt is made up of, as shown by the red lines, 6.4GT from fossil fuels and 1.6Gt from land use change; that totals 8Gt from all human activity.
8Gt is 3.67% of the total emission flux annually.
Unless John Byatt can understand that there is no point proceeding.

From your post
"In 2009 Australia was 16th of the world’s nations CO2 emitters, emitting 374 million tonnes or about 1.28% of ACO2".
Here you have given the correct amount for 2009
what you deny is that what remains in the atmosphere is all due to humans
If australia is responsible for 1.28% (2009) of emissions then it is responsible for 1.28% of what remains in the atmosphere
if cohenite cannot understand basic logic then there would be little point proceeding here.

I told you Byatt, if you come over here and started insulting and making your typical arrogant judgements you would not be tolerated.
Byatt promulgates 2 bits of stupidity, which constitute the extent of the alarmist’s argument that the increase in CO2 is entirely due to ACO2; the first stupidity is:
“If australia is responsible for 1.28% (2009) of emissions then it is responsible for 1.28% of what remains in the atmosphere”
This is stupid because as the official numbers show human CO2, ACO2, is 3.67% of the total emissions per annum; of that total 1.5% is retained in the atmosphere; the proportion which Australia puts in MUST be 1.28% of 3.67% of 1.5%.
How could it be otherwise; if what Byatt is saying is true it must mean NONE of the natural CO2 is retained in the atmosphere; in other words natural emissions of CO2, which are the vast bulk of them, are perfectly matched by natural sinks or absorption.
If that were the case there would NEVER be any variation in CO2 levels.
The other stupidity which Byatt regurgitates is this:
“100% of what remains in the atmosphere is due to humans or about 43% of our emissions (knorr)”
Knorr does not say this; what Knorr says is that the “airbourne fraction” [AF] of ACO2 has not changed since 1850. This does not mean that ACO2 has not contributed to the increase in CO2; what it means is that greatest proportion of increase has been from natural CO2; it can be explained in the form of a constant in an increasing total: say ACO2 is 20% of CO2 which is 100. So ACO2 is 20; when CO2 is 200 ACO2’s 20% will be 40 so natural CO2 has contributed 60; at 300, ACO2 is 60, natural CO2 is 140 and so on. Natural CO2 must be contributing to the increase in total CO2 and sinks must be expanding as well. Since the AF is constant both natural CO2 emissions and natural sinks must be expanding.
In short Byatt and the alarmists do not know what they are talking about.
I have removed Byatt’s last comment because he got personal and if I want to be insulted by the likes of Byatt I’d go to the ABC. If Byatt wants to make any further comments they should not be personal.
Apologies for lateness.

Hi Bill, still having site problems?
posted this about 7pm last night, still has not appeared
will repeat here,
Introduction Knorr 2009
[2] Of the current 10 billion tons of carbon (GtC) emitted
annually as CO2 into the atmosphere by human activities
[Boden et al., 2009; Houghton, 2008], only around 40%
[Jones and Cox, 2005] remain in the atmosphere, while the
rest is absorbed by the oceans and the land biota to about
equal proportions [Bopp et al., 2002]. This airborne fraction
of anthropogenic CO2 (AF) is known to have stayed
remarkably constant over the past five decades [Jones and
Cox, 2005], but if it were to increase in a way predicted by
models, this could add another 500 ppm of CO2 to the
atmosphere by 2100 [Friedlingstein et al., 2006], significantly more than the current total. While recent studies have
highlighted a decreasing ability of the Earth system to
absorb the excess CO2
Anthony says:
DeleteThe problem Byatt has is the fundamental one all AGW science has; it cannot distinguish between reality and what the computer models predict. Knorr’s study shows NO variation in the % of human CO2, ACO2, in the atmosphere for the last 150 years. Yet Byatt concentrates on Knorr’s noting that the AGW models, which have been wrong about everything, are saying the % of ACO2 in the atmosphere MAY change in the future and what will happen IF the AF does change.
There is no evidence for this, only model assumptions. And Knorr’s findings have been verified by Gloor et al:
http://www.atmos-chem-phys-discuss.net/10/9045/2010/acpd-10-9045-2010.html
As for sinks or the capacity of nature to absorb more CO2, declining, that is nonsense as is shown by Gloor’s response to Corinne Le Quéré, one of the leading advocates of the idea that natural sinks are exhausted:
http://www.atmos-chem-phys-discuss.net/10/C4233/2010/acpd-10-C4233-2010-supplement.pdf
As usual Byatt demonstrates he is a typical disciple of AGW whose belief trumps any and all evidence.
