This means that for every 1,000,000 molecules of air you will only have 383 molecules of CO2 or 0.0383% per volume. You can believe what you want but I don't see how 383 CO2 molecules per million air molecules makes a difference. It is only because we live in the age that we do that we can even measure such a small amount.Alex Finlay wrote:I care more about our O3 (Ozone) levels.
Yea, I believe this to be another myth. Please explain how O3 (Ozone) is found as a layer in the upper atmosphere when it is heavier than O2(oxygen)? 03 should sink to the ground, not hover overhead as a protective layer! Also O3 is found in higher concentrations near the equator than at the poles because it's heavier, remember, air behaves as a fluid and the earth spins so centrifugal forces are at play here.
That explains your ozone hole at the poles, no need to worry anymore; so turn off the TV & read some books for a change.
Well it has to do w/ the fact that it forms up in the stratosphere.
High levels of short wave radiation break apart oxygen molecules (O2) into 2 oxygen atoms. Since oxygen isn't stable alone, it will recombine. Sometimes it recombines w/ two other oxygen atoms to form O3 (ozone).
Ozone can form in the troposphere by exposing fossil fuels to solar radiation. You know, like pumping gas on a hot summer afternoon. Surface ozone is dangerous. Ozone is toxic to humans. Much less gets formed down here b/c we are much more protected from the high levels of short wave solar radiation.
Ozone is created at all heights in the atmosphere. Ozone at ground level is formed by electronics and heat from cars (predominantly) and forms smog. Ozone at ground level is bad. Ozone is also formed in the upper atmosphere though absorption of UV light. It is formed in the upper atmosphere and kept there through the pressure differential that exists (higher air pressures below holding it up). Ozone is also very reactive, so generally is lives and dies in the upper atmosphere when formed there.
And just because something has such low percentage doesn't mean it has an affect.
For example the sun is making billion of billions of rays of light, now if every single Gillatones of Co2 is refletching that heat back into our atmosphere Traping it, it will make an effect.
I found your statement about TV rude to be honest, i read as much as a watch.
Air does behave as a fluid but do not forget dencity.
E.G Oil will float above water.
if you mix it in it will go up again.
