does anybody know why the greenhouse gas doesn't rise up through the atmosphere and go into space? Is it heavier than air? I probably sound dumb but I'm trying to understand this.
The Earth's atmosphere is mostly Nitrogen. Carbon atoms are lighter than Nitrogen, and Nitrogen atoms are lighter than Oxygen, which is lighter than Fluorine Atoms (You can see the atomic weights of atoms in the Periodic Table of Elements).
Many greenhouse gasses are lighter than air, but even the lighter ones still weigh something, and are drawn to the Earth by gravity, its just that they 'float' on top of the heavier atmosphere.
Gasses also do sublimate into space, but not particularly fast, or otherwise we'd have lost our atmosphere by now.
Incorrect.
You need to look at CO2, not carbon itself
CO2 has a density of 1.98 kg/cubic meter and is thus HEAVIER than Nitrogen at 1.2 kg/cubic meter
I never said CO2 was lighter than Nitrogen. I said a Carbon atom was lighter than a Nitrogen atom. I was referring to atomic weights for individual elements, not compounds.
Molecularly, Nitrogen molecules consist of two Nitrogen atoms. And molecularly, CO2 consists of two those two atomically heavier Oxygen atoms and a Carbon atom that makes it quite heavier than gaseous Nitrogen.
Still wrong
You don't understand atomic weights and the difference with density
Comparing a gas like Nitrogen to a solid like carbon is ridiculous.
In solid sate, carbon has a density of 2200kg/cubic metre
In solid state, Nitrogen has a density of 1027 kg/cubic metre
Nitrogen is still lighter than carbon
Depending on the allotrope, molecular carbon consists of between 4 to literally hundreds of atoms, which packs a lot of atoms into a small space, and therefore the density of a collection of lighter carbon atoms can be far greater than that of gaseous (and very loose) collection of two atom molecules of Nitrogen.
Nonsensical argument. Why don't you use the density of a neutron star while you are at it.
Sorry you are wrong
Nitrogen is lighter than CO2 and/or Carbon
Period.
But carbon atoms are lighter than nitrogen atoms, which are lighter than oxygen atoms.
Density is related to pressure in gasses, and is variable, as is the 'weight' of a gas. If you warm a gas at equal pressure, it rises up, because it is less dense, and so by volume, is lighter.
No, just NO!
I am trying to be as patient and respectful as possible, but you are pushing "flat earth arguments"
You seemingly have no understanding of basic science, even at a high school level
Density is not exclusively related to gases: you can measure density in gases, liquids and solids, at various temperatures and pressures.
For a given temperature and pressure, nitrogen is always lighter than carbon
For a given temperature and pressure, nitrogen is always lighter than CO2
For more tangible proof, look up the 1986 Lake Nyos disaster:
en.wikipedia.org...
"The eruption triggered the sudden release of about 100,000–300,000 tons (1.6 million tons, according to some sources[who?]) of carbon dioxide (CO2).[2][3] The gas cloud initially rose at nearly 100 kilometres per hour (62 mph; 28 m/s) and then, being heavier than air (and air is 70% nitrogen), descended onto nearby villages, suffocating people and livestock within 25 kilometres (16 mi) of the lake.[4][5]"
So, thousands of people died BECAUSE CO2 IS DENSER, HEAVIER THAN AIR/NITROGEN
Clear enough ?
Give it up.
You are wrong - accept it
QED
But I never wrote that CO2 is lighter than air, which is mainly nitrogen.
I wrote that atomic carbon is lighter than atomic nitrogen - and it is!
The relative weights of different compounds is basic chemistry.
Two 'heavier-than-a-nitrogen-atom' oxygen atoms, plus a 'lighter-than-a-nitrogen-atom' carbon atom, three atoms in total, with two of them heavier than nitrogen atoms, are in total heavier (at the same pressure and temperature), than two nitrogen atoms.
It is clear that what you believe I wrote, was not in fact, what I wrote.
ABSOLUTE nonsense !!
Carbon is NEVER lighter than Nitrogen.
Spewing ignorance infused non-science drivel
Carbon: Standard atomic weight Ar°(C) = 12.011±0.002
Nitrogen: Standard atomic weight Ar°(N) = 14.007±0.001
Look it up in the periodic table.
No, not true just because of the atomic number and weight.
I ALREADY showed you in this thread that the natural carbon can't exist as C atom like that. Carbon is not a gas like O2 or N2 anyway. It is found in a solid attached to a chain of other atoms and likes to have other carbon atoms in its molecules. The Carbon Atom is ready to react to other atoms and most molecules known to man. We use it to purify things for one example because it will absorb a lot of things. CO2 is a gas and it is heavier than N2 and it can combine in plants to make solids again.
As a grad student I taught this type of thing to the freshman in lab class experiments.
CO2 is NOT the only molecule that is in gaseous phase at standard temperature and pressure (STP) and that is also based upon at least one carbon atom.
Methane gas consists of one carbon atom and four hydrogen atoms and is a lighter gas (16.043 g/mol) than N2 gas (28.014 g/mol).
Acetylene gas consists of two carbon atoms and two hydrogen atoms and is a lighter gas (26.038 g/mol) than N2 gas.
Carbon Monoxide gas consists of a carbon atom and an oxygen atom and is a slightly lighter gas (28.010 g/mol) than N2 gas.

Ok you can add atom wts. You don't seem to grasp what I am saying so that's why you are using a shotgun approach. Basically, NO you don't get it. Because you want to believe lies out the gate, AND anybody discussing this information logically needs to learn enough chemistry before attempting to speak with someone who has without insulting us for using the lies as data and then trying to imply you understand atmospheric chemistry when the experts are still learning about it.

For the first part, yes the water level would indeed increase and is one of the main reasons for rising sea level. Pictures can be misleading which is why scientists use tidal guages to measure these things.
I'm not sure what pictures you're refering to as I don't remember such posts but I posted the graphical data of the tidal data from the Sydney harbour post earlier in the thread (last page) which shows it rising.
The reason you can't see it is it is very slow and only a few inches rather than a dramatic rise like 2m which would flood a lot of coastal cities.
If pictures are used as a form of evidence then a lot of vvariables need to be controled or removed in order to create an accurate measure and produce reasonable reliable data - unless the picture in taken at the exact same place and height it wont be an accurate measure and the data would be incorrect and lead to a misleading conclusion.
EDIT:
Personally if I was doing an analysis and/or creating a mathematical model I'd use the tidal guage data as it provides accurate data and introduces minimal variables then compare all the data to history of storm, wind speeds, sea temperature to account for the variables that effect sea level and create reliable data.
I'm biased as I'm terrible at taking pictures but I don't think I've ever read a paper using pictures as data - tidal guages and sea temperature is what is currently used to analyse sea level

The water mark is higher on the newer pcitures but without knowing exact times, dates, conditions etc...it isn't a scientific proof or usable data. I recommed using the data from the station pictured that I posted earlier in the thread for a proper accurate source of high and low tide historical records and shows a clear rising trend consistent with all other data,
There's an elevation map of the shoreline in question here map which shows the coast in question as between 8m and 80m above sea level so the known rise of a few inches wont have much visible effect at that paticular location.
The difference is that the rate of rising and rate of melting land ice is dramatically increasing in recent times.
The current maxima/worst case scenario (5% chance) is a 2m/6.5ft rise by 2100 which would displace around 200m people and lose 100s million sq km of land
The current minima/best case scenario (5% chance) is around 0.6m/2ft rise by 2100 which would still cause displacement of 10s of millions.
If things carry on as current then we're highly likely to experience a 1m/3.3ft rise in sea level by 2100 which has similar displacement as above but the rate of rising sea is 6 - 8x what it was from 1900 - 2000.
