'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?

Very educated and point driven blog. I don't know if the increase in natural event's, (ie: the Cyclone, Earthquakes in China and Asia, Tornado's throughout the Midwest and South) is related to this pressure theory or not. But it does sound somewhat plausible.
Look, we know that the deeper into the Ocean an object goes, the more pressure that object feels around it's body. So I agree that the pressure is stronger the closer to the core of the earth we go.
Good blog sir.

Or maybe as the moon travels away from the earth changes in lunar gravity is affecting more than the tides.

Well, our poles are switching as well, something like 11 degrees this last year if I remember correctly, and that might explain some other things like why it seems (at least to me) that our seasons are lagging... winter starts late, and summer as well. But more water in the atmosphere would do that as well... causing a 'lake effect' on a larger scale??? I have always believed that more water in the atmosphere means more volitility, as its a major factor in tropical storms, but I wondered if there was a way to quantify barometric pressure on a worldwide scale, like the evaporation 'scale' that farmers worldwide use (and which has proven 'global dimming'). Some like to argue that more water in the atmosphere is a good thing (part of the global warming debate, that global warming would be a good thing because then deserts would get more rain), but this just isnt the case. I would agree that it makes for more violent storms though, as some scientists argue that the few degrees we have added already are the cause for the dramatic cyclones we get.

But I just thought... wouldnt there be a way to quantify more water in the atmosphere then?

You are correct! hah, the poles ARE reversing!!......wake up people!!

Earth's north magnetic pole is drifting away from North America and toward Siberia at such a clip that Alaska might lose its spectacular Northern Lights in the next 50 years, scientists said Thursday.

Despite accelerated movement over the past century, the possibility that Earth's modestly fading magnetic field will collapse is remote. But the shift could mean Alaska may no longer see the sky lights known as auroras, which might then be more visible in more southerly areas of Siberia and Europe.

The magnetic poles are part of the magnetic field generated by liquid iron in Earth's core and are different from the geographic poles, the surface points marking the axis of the planet's rotation.

Scientists have long known that magnetic poles migrate and in rare cases, swap places. Exactly why this happens is a mystery.

"This may be part of a normal oscillation and it will eventually migrate back toward Canada,'' Joseph Stoner, a paleomagnetist at Oregon State University, said Thursday at an American Geophysical Union meeting.

Previous studies have shown that the strength of the Earth's magnetic shield has decreased 10 percent over the past 150 years. During the same period, the north magnetic pole wandered about 685 miles out into the Arctic, according to a new analysis by Stoner.

The rate of the magnetic pole's movement has increased in the last century compared to fairly steady movement in the previous four centuries, the Oregon researchers said.

At the present rate, the north magneti

(con't) --pole could swing out of northern Canada into Siberia. If that happens, Alaska could lose its Northern Lights, which occur when charged particles streaming away from the sun interact with different gases in Earth's atmosphere.

The north magnetic pole was first discovered in 1831 and when it was revisited in 1904, explorers found that the pole had moved 31 miles.

For centuries, navigators using compasses had to learn to deal with the difference between magnetic and geographic north. A compass needle points to the north magnetic pole, not the geographic North Pole. For example, a compass reading of north in Oregon is about 17 degrees east of geographic north.

In the study, Stoner examined the sediment record from several Arctic lakes. Since the sediments record the Earth's magnetic field at the time, scientists used carbon dating to track changes in the magnetic field.

They found that the north magnetic field shifted significantly in the last thousand years. It generally migrated between northern Canada and Siberia, but it sometimes moved in other directions, too.
