'Global dimming' was found out through the evaporation rate info being collected throughout the world.  I hope you know what I am talking about here, if not, I can post more on that,  but I have been thinking of other ways to measure global changes... and Ive been wondering...

If more water is being released into the atmosphere, causing more violent weather changes, storms, etc... wouldnt it be accurate to also say that our global barometric pressure should also be going up?  People may not think about it, but we are at the bottom of an ocean of air on our planet, and the deeper you go in a gas or fluid, the higher the pressure.  Now, Im not claiming that the atmosphere is expanding, but if there is more water in it, more CO2, etc... this would make the air in the atmosphere (mostly troposphere) more dense, wouldnt it?  Or would the height where the troposphere and stratosphere meet possibly lower?  Just wonder if there is any validity to this approach of 'global barometric pressure change'.  The additional pressure in the atmosphere would then also create higher pressure underwater, as well as underground... maybe insignificant, or maybe just enough to tip the geological scale to create more earthquaes, volcanic activity, etc.

Is this possible?  Worth looking into?  Are global barometric pressure logs kept like the evaporation rates?
