Re: Global dimming?
then their is no danger of an identical covering such as Venus actually has, but at what level if it is even possible could earth also have a covering of similar form, but of a different gaseous makeup?

what I'm asking is: by adding the carbons to our atmosphere, is the water containable space shrinking, and if shrinking, could the less air volume to support water mean that global warming could cause the sky to become permanently covered?

this is what i mean by Venus effect, a solid covering that would block most light from the surface.

I'm just exploring potentials, and wondering what data on our atmospheric capacity is available.

Check out partial pressures

quote:
In a mixture of ideal gases, each gas has a partial pressure which is the pressure which the gas would have if it alone occupied the volume. The total pressure of a gas mixture is the sum of the partial pressures of each individual gas in the mixture.

Gases dissolve, diffuse, and react according to their partial pressures, and not necessarily according to their concentrations in a gas mixture.


In other words the concentration of one gas doesn't affect the concentration of other gases.

Enjoy.

Re: Global dimming?
Nitrogen narcosis is a problem with gas mixes containing nitrogen. A typical planned maximum partial pressure of nitrogen for technical diving is 3.5 bar absolute, based on an equivalent air depth of 35 metres (115 feet).

The expected number of particles with energy ei for Maxwell–Boltzmann statistics is Ni where:

ah well..didn't get the math..its above my head ill have to withdraw, but I'm still uneasy, what i can understand of the math appears to be valid in controlled states of temperatures and pressures. i don't understand the three different types of gases and how their relevant to each other exactly (divided by at what temperature the product becomes a gas?)

it still stands to reason that the extra pressure of having a heavier atmosphere will have effect on weather patterns at the least. i think too much is being overlooked but i wouldn't know where to start. don't have the knowledge.

thanks razd tho, for what you did throw on the table, i can only wait and see, how this global warming is going to pan out.

Re: Global dimming?
The important thing is to notice that the (partial) pressure of H2O does not depend on the (partial) pressure of CO2 or other gases, rather it is dependent on temperature and the (partial) pressure of H20.

Enjoy.
