Well that does seem a far less sinister set of circumstances than what was being implied, but because of that implication I still would prefer to see a much fuller explanation supplied, and absolutely all doubt removed so that no denialist can make any good faith claims about this in the future.

That they would be able to attack the credentials of the raw data itself would lead to intolerable confusion, and there will already be many who have this tucked away in their minds as the absolute proof that all those crooked scientists were just making the whole thing up, just like cousin merle told 'em at the hoedown, and no amount of evidence to the contrary will ever sway them from that view, unfortunately.

Real damage has been done, and it will stay done for most denialists.

You'll have to read a bit further than the summaries, Soren. This thread and the sticky thread has the basic information.

Would a measurement of your blood alcohol concentration not be a demonstration of whether or not you had been drinking excessively?

Isn't that what measurements do?  They provide a demonstration of a fact.

It wouldn't matter how many times you explain the truth. They thrive on urban legend - urban legend that is deliberately manufactured.

It's just what they do.

It's not related to the raw data. Actually both the Hadley Centre and NASA are not very keen to release raw data these days simply because it is so easily manipulated by people who wait on every new month's data.

I can't see how it possibly could backfire for them muso, they have evidence that shows people discussing the subject in non-scientific terms, to try and convey as strongly as possible the threat potential of global warming.
Now while that is not actually anything startling, it does not indicate a dispassionate scientific approach either, so it can be used by denialists to infer that if they are seeking to highlight the data which best fits their theory, are they suppressing stuff that does not?

I think that unfortunately, this will be more than a storm in a teacup, and also that it will provide ample ammunition for denialists to further confuse and deceive a public becoming more susceptible to their spurious claims.

I think this is bad, very bad, for the cause of real science, and rational debate.

I should add that I do not think there is anything sinister going on, and I do not believe that any real scientists have been shown to be falsifying their data, that realm belongs squarely in the denialists camp, but I do think this will steel the resolve of many denialists, and spur them on to even greater attempts at deception, to balance the books from their perspective, which they see as countering the governments lies, with lies of their own.

OK, a good play of devil's advocate. How about the fact that we saw him drinking a bottle of Vodka at lunchtime, we confiscated the bottle and carried out an analysis on the residue and confirmed the composition of the drink. A policeman followed him from the bar and noted him getting into the car while (soren was) swaying in a drunken fashion, then asked him to blow in the breathalyser. The reading corresponded to typical readings that would be expected for a man of his body mass who had just consumed 0.7 litres of Vodka of the concentration determined by the analysis, and a later blood sample was taken which confirmed the breath reading.

Actually that's a closer analogy of how certain we are that anthropogenic CO2 is causing/ will cause global warming.

Ah but of course
, the policeman's attention could have been drawn by a very attractive brunette walking in front of him, and at that very moment, Soren's identical twin brother who had just finished drinking the original bottle, headed for the restrooms, while quite coincidentally Soren was walking down the street wearing identical clothing. The breath alcohol reading was actually caused by the same grapes that had fermented in his stomach, and the blood samples were of course switched by an evil scientist who had been having a heated debate with him on the Australian Politics Forum.

So based on that, yer honour, the man is innocent.

Muso,

You offered the 5 points as proof of causal relationship between AGW and CO2. But I do not think these 5 points demonstrated anything like a causal link.  As I said, they are 2 statements, two measuremenst and an assertion. There is nothing wrong with statements and measumenst but they do not demosntrate causality or even correlation. If your summary is not a demonstration of CO2 causing AGW, then the expanded version won't be either, no matter how many pages it fills.

Blood alcohol: a very silly analogy, the type that gives a bad name to AGW. The heart of the dispute, the scepticism, is NOT whether we are putting alcohol/CO2 into the blood/atmosphere. That is a matter of measurement.

What is disputed is about whether our CO2 is or is not causing global warming. The causal relationship not been has not been demostrated.



Even if we used your analogy, we are way under the legal limit: 0.0387% of CO2 in the atmosphere, if translated to alcohol consumption,  is less than a tenth of the legal limit of blood alcohol. Despite decades of increasingly wild pissups.
Cheers  Wink

I'm really at a loss as to what your standard for a causal link are.

Let's look at Point 1 again, and it becomes obvious that it's not just a statement.

1. The undeniable fact that carbon dioxide is a greenhouse gas whose specific absorbance (for want of a better term) at infrared wavelengths, can be measured quite accurately and compared to other greenhouse gases.


It is a statement of fact that can be (and has been) verified. It is a basic property of the carbon dioxide molecule to absorb infrared radiation, and I've even described the mechanism for that in terms of bond stretching and vibration.  

All the other conclusions stem from that basic fact. CO2 absorbs infrared radiation, and the extent to which it does that, can be measured, and is known to a very high degree of accuracy.

Al the other measurements serve to confirm the mechanism.

It's a basic parameter than can be measured just as easily as the melting point of pure ice under standard conditions.

Ok, I realise that it's meant to be a frivolous statement, but how do you measure the legal limit? I do it on the basis of risk.

When you say "OUR" CO2, is that an indication that you think CO2 is the driving force behind global warming, but that mankind's contribution to the total amount of CO2 is negligible, compared to naturally occurring CO2?

Because if that is all that is bothering you then that aspect has been pretty extensively covered, and I am sure muso can once more go through the various carbon signatures for you, as well as supply the relevant measurements of the naturally occurring CO2.

I know Plimer was ridiculed by the real scientists for pushing that particular barrow, and as you still seem to regard him as a credible source, perhaps that basic issue needs to be re-addressed for you?

I fear that rather than this being the case, you are just whizzing around on the never ending denialist merry go round, where issues are addressed one by one, scientifically debunked, only to then reappear after all other issues have been answered, to be put forward yet again as a valid reason once more, as if the previous debunking had been olbliterated from your memories.
Perhaps that is the "REAL" natural cycle that denialists are talking about?

It IS unusual in SA.

I was just pointing out the idiocy of saying the hacked emails said there was no AGW.

Re the heatwaves, in SA we have had so many in the last 3 years (both spring and fall) that it is a 1 in 200,000 chance that these were not caused by some agency--the only agency being AGW.

I will keep an anxious eye on my 88yo mother this summer, max temperatures in Adelaide, 48.5C last year--another record--will likely exceed 50C. I predict that about 2000 elderly people in SA & Vic will die from the record high summer temperature. Do you have any elderly relatives? If you do, any harm in making sure they will be OK at the height of summer heat? Not only AGW you know: the sun is entering a more active state and the Pacific is warm both on the Aust side AND the S American side.


I think it is being suggested that the hacked emails show references to manipulating data and peer review and other unsavory behaviour. Also i think you will find the hottest temperature for Adelaide was 12 January 1939, 46.1 °C.

PS people die from the cold too.


They do but not in Adelaide. Nope, we reached 48.5C last summer!

So you are suggesting that this basic property of CO2 is your reason for declaring human CO2 to be the cause of global warming?

I have not seen any other cause suggested by you or othres.

I don't know if you're being deliberately obtuse. I have probably been simplifying this too much.

The basic property of CO2 to absorb infrared is the first part. This is the effect that traps a greater proportion of the heat in the troposphere.


We know that it absorbs IR and we can monitor that by satellite.
We know how much we put there (from source and isotopes).

We also know how much extra water vapour will / has been partitioned into the atmosphere as a result of the temperature rise due to CO2 and can do a back calculation to confirm the climate sensitivity of about 3 degrees per doubling of CO2. Approximately 1 degree of this rise is due to the CO2 itself, while the other 2 degrees are due to the water vapour.


As a confirmation, we can look at the paleoclimate record from ice core data and we can confirm that this relationship between temperature and CO2 has applied over the last 850,000 years or so.

Over the years, various workers have conducted independent work that show varying levels of climate sensitivity, centred on about 3 degrees for a doubling of CO2.

Here is an example of such a paper. It's well worth reading through it.

AGW is actually happening and it will get worse.  The risk in question is not just about the consequences of AGW.  The increased CO2 in the atmosphere has also caused a gradual drop in ocean pH - and that will get worse with time too.

The latter will be the one that hurts us soonest when it really starts to impact on ocean ecosystems. Taken in combination with overfishing and depletion of fish stocks, it is likely to have a very significant effect.

You would be best if you could read the Copenhagen Synthesis Report. That has a good discussion of the nature of the risks and how a 2 degree guard rail is a good economic compromise.

Quote:
Evidence indicates that ocean acidification is a serious threat to many organisms and may have implications for food webs and ecosystems and the multi-billion dollar services they provide. For instance, erosion is likely to outpace growth of tropical coral reefs at 450-480 ppm CO2; there are already reports of a 19% decrease in growth of Great Barrier Reef corals.


Incidentally, have you noticed how crayfish and prawns are becoming more plentiful?  That's a result of overfishing. There are fewer predators around.
