Co2? A cobalt filled balloon would be kind of heavy; I’m guessing 150kg.
A few years ago there was a conscious decision by government funded agencies and allied green corporations to portray CO2 as a pollutant, to achieve this aim they needed to get their message across via the MSM.
To instill the desired notion and belief in the population this alliance had to adopt and use the methods of the visual media(TV)and there are plenty of experts in the media/advertising world only too keen to help and assist this highly funded alliance.
The tricks to portray CO2 as a pantomime villain are easy to spot yet they are very effective in producing a short term acceptance in the greater population, in effect we have been sold a product.
Dramatic mood setting music,lighting and sounds set the stage and the then the visual tricks like showing CO2 spewing out of power station chimneys and black balloons etc, the tricks used by the advertising community are varied and very clever yet even their dark skill is only effective for a short time, a limited shelf life so to speak.
The greater public can be misled and duped and confused for a time and then saturation occurs, combine this with the contradictory experiences of real people in the real world discovering that the product sold does not align with peoples experiences. A product however aggressively sold has to eventually meet the expectations of the consumer, the admen will tell you that all the money in the world cannot make a bad product a success, they can only make people take notice until consumers experience the product in the real world at which point the product lives or dies on its merits.
You can fool some of the people all of the time and all of the people some of the time bu you cannot fool all of the people all of the time, it looks like the media driven ad campaign has come to the end of its useful life. If someone were to add up all the advertising expenditure spent on flogging the AGW campaign against CO2 it would be a stunning amount of money.

I didn’t notice any expanding balloons! Odd!”
Try the first 10 seconds of the film. You are only seeing what you want to see. The problem is so real that I’ve banned my kids from putting black balloons in both the washing machine and the coffee maker. Real Climate are right behind me on this. Thay can see the danger. But the black balloon manufacturers are funding the sceptics.
Think of our children’s children and ban black balloons now.
Makes you wonder why clowns like the New Labour department for education seemed set on making “difficult” subjects like “science” a dumbed down travesty of itself designed to indoctrinate kids into the AGW scam but not learn any real science. They even managed not to teach 25% kids not to be able to read or write adequately before leaving school.
To paraphrase Orwell – ignorance is power. No wonder successive governments wrecked the grammar school system. It actually educated kids to a high standard. Some of us still remember that CO2 filled balloons bounce gently across school lab floors…
Yup. This inane advert has been floating around Victorian (Australian) TVs for a few years now. Funded by mug taxpayers like me. When I point out to warmist acquaintances that CO2 is actually heavier than air, so the balloons couldn’t float, and that it’s just classic agitprop they’re being suckered by, a sort of ghastly glazed expression comes over them and they stagger off and I don’t see them again for months. And these are educated people!
Lost a lot of friends that way, so it’s not entirely bad.
I deal with CO2 scavanging systems occasionally, and there are no real health concerns until the concentration reaches about 7%. The real hazard is O2 concentration. When that gets above about 18% in local concentrations, that is a blaze waiting to happpen. and don’t get me started on the dangerous polutant dihydrogen-oxide.
While CO2 is not toxic in small concentration, we can’t easily survive “tens of thousands ppm”. At 20,000-50,000 (2-5%) ppm it can cause nausea, dizziness, etc. At higher concentrations, consciousness and death will follow.
When you work with CO2 an alarm is required; a first alarm is sounded when 5,000 ppm is reached (maximum allowed for long-term exposure); the area must be evacuated at 40,000 ppm.
As it is heavier than air, it settles near the bottom, in ship’s holds, caves, wells, etc.

The CO2 in the balloons warms by stopping the outgoing IR radiation and so expands, reduces in density and so floats the balloons upwards. Simple physics;>)
—–Reply:
Since CO2 is about 1.5 times heavier than typical air, it would take considerable heating and resulting expansion to make a CO2 balloon float.
BTW, CO2 can be a serious problem in old mine workings where it collects in low-lying areas and builds to concentrations that can be fatal to anybody that walks into it.

___________________________________
It can be a problem in caves too. But it is from the decaying of organic matter coupled with a still atmosphere. There is a good article about the physics of gas mixing in the atmosphere and local striation in The Journal of Cave and Karst Studies, v. 71, no. 1, p. 100–107: The legend of carbon dioxide heaviness
Conclusions:
“Confusion between stationary and transient conditions has created a false underground legend of gas entrapment, which obscures recognition of the true processes that produce carbon dioxide, methane, and radon traps in caves and mines. The basic concepts have been further confused by the fact that if carbon dioxide is produced by oxidation near its source, there is not only high carbon dioxide concentration, but also a very low oxygen concentration, which leads to the occurrence of flame extinctions and similar evidences of poor atmospheres. The traps are essentially due to accumulation near a source (whatever the origin) in motionless atmospheres. The up-down gradients are generally due to (1) preferred point of organic accumulation and (2) air thermal stratifiation that creates a motionless trap of cold or warm air. Structure, periodicity, and intensity of traps depend on organic matter inflow, thermal stratifiation, and shape of the cavity.”
I always thought it was CO2 that came out of cooling towers! Certainly most of the MSM do since there always seems to be a photo of them whenever an article on global warming appears. The alternative, of course, is a polar bear on an ice berg.
You mean its only steam…….?
Out here in the midwest, I have seen tankers carrying CO2 heading for the greenhouses. But I have never seen a flammable symbol. Every time I see one I just have to chuckle.

It must be worse than we thought!

50 Grams of GHG per balloon. I think that amounts to a bit of fraude.”
You obviously forgot about the GHG multiplier effect. The good part is you get to pick the multiplier that makes your numbers work out.
John Eggert says: “Could that person…explain why air measured temperature decreases at a slower rate on humid evenings than dry evenings?” Possibly because water vapor has a greater heat capacity than an equivalent amount of air. Humid air will then have a higher heat capacity than dry air, and will take a longer time to decline in temperature for the same rate of cooling (heat/unit time).
Jimmy says: “Greenhouse gases are those that absorb the IR radiation given off by the earth, but don’t absorb the visible light of the sun. Hence, they allow energy in, but not out. They may not trap ALL of it, but the more molecules of GHGs there are, the less heat is released.” Not true. Gases that have molecular absorption/emission bands in the infrared ALSO EMIT infrared in those same bands, as Tom Vonk explained (sorry, I have only one font to work with). The gases themselves do not accumulate heat, because they are in equilibrium. They only re-emit heat absorbed from a single direction (ground upward) into all directions (half upward and half downward). Thus, they always allow half of the energy “out,” maybe more if the absorptivity is not saturated. This gets into the concept of “optical depth,” which is a measure of whether the atmosphere is effectively transparent (optically thin) or opaque (optically thick). Once the atmosphere becomes optically thick, any further concentration of “absorptive” gases makes no difference. (Aaron Stonebeat is correct.)
Ric Werme says: “Since water vapor is lighter than air, it would be a cheap substitute for helium [in balloons] and a lot safer than hydrogen.” So true. But the vapor would have to be at boiling temperature in order to balance atmospheric pressure (this is what defines boiling point: the temperature at which a substance’s vapor pressure is equal to atmospheric pressure). This is called steam. And it would work, provided you could keep it heated. (Ammonia would actually work better; it has lower molecular weight and has a vapor pressure equal to atmospheric pressure at normal temperatures. Or methane, as someone else has already observed. Don’t pick acetylene!)
I lost track of another point: Someone mentioned the idea that CO2 should settle out of the atmosphere, or be found in higher concentration at low altitudes. This cannot happen in the troposphere, which is defined by the fact that it is in a state of convective mixing all the time. Atmospheric composition is therefore a constant up to the tropopause (excepting water vapor, which has evaporation/condensation dynamics). Once you get into the stratosphere, it is possible to notice slight changes in composition in unmixed layers (such as the presence of ozone).
Why was I not surprised when I saw that this is from Australia. The government has gone nuts here, I just hope they don’t destroy our economy before someone sees sense.

Fortunately the good people at http://www.dhmo.org/ have done some wonderful work looking into this dangerous chemical!
I said “don’t get me started”
“Fortunately the good people at http://www.dhmo.org/ have done some wonderful work looking into this dangerous chemical!”
That is just frightening.
Apparently the majority of fatalities connected with this dangerous chemical are from inhalation.
So I went around the house and did some pseudo-scientific tests to determine if it was present.
I found some, and couldn’t wash it off, just as they say ! Now it is coming out of my eyes !
And what is worse, my swimming pool seems to be polluted with literally thousands of gallons of the stuff. What to do ?
