the uk have seen the wettest summer in 100 years in 2012 and not much difference this year so far

Sorta sounds like a dumb question but I wonder... The earth's water cycle definitely has been disrupted - and while some places are experiencing the opposite of drought (heavy precipitation and flooding) I recall reading that our fresh water IS disappearing and not being "recycled."

DUH.....

That's where the aliens come to our planet through.....That hole in the ozone I mean....

Everybody knows that......../sarcasm

Is our water vapor leaking through the hole in the ozone?

Brief answer: no.

Longer answer: 99% of our water vapor is in the lowest layer of the atmosphere, the troposphere. If any molecules (which are heavier than plain oxygen (02) because they have an attached hydrogen atom) get into the stratosphere, they usually get ionized.

So, water vapor is so heavy that 99% of it never makes it as far as the ozone layer.

While your conclusion is correct, your chemistry is way off. Diatomic oxygen(O2), the natural state in which most oxygen exists has a molecular weight of 31.88 +/- 0.0008 grams/mol.. Water vapor (H2O) has a molecular weight of 15.83 g/mol. So, water vapor is about half the weight of diatomic oxygen. I'm guessing you got confused about the chemical formula for water and were thinking of HO2, which does exist in the atmosphere as a hydroperoxl radical, an important atmospheric cleansing agent.
The real reason that water vapor exists in the troposphere and not higher is that the adiabatic lapse rate results in saturation and precipitation as the air gets cooler. Each pound of dry air today in Miami (60% humidity) can carry 159 grams of water vapor. At 15,000 feet, it is down to about 14 grams water vapor per pound of air.At 39,000 over Miami today, the temperature is -65F. At that temperature the water vapor load carrying ability is almost 0. At an average, the ozone layer is at about 75,000 feet. So water vapor would condense or freeze and fall to earth long before it gets there.

The Earth is pretty much a "closed system," like a terrarium. That means that the Earth as a whole, neither gains nor loses much matter, including water.

....very little of Earth's substances escape into outer space. This is certainly true about water.

This means that the same water that existed on Earth millions of years ago is still here. Thanks to the water cycle, the same water is continually being recycled all around the globe.

This↓ may not actually be relevant for this specific topic. It is something that I had forgotten about, until now. I just think that it's quite interesting.(even though it is difficult to believe)

The drawings below show various blue spheres representing relative amounts of Earth's water in comparison to the size of the Earth. Are you surprised that these water spheres look so small? They are only small in relation to the size of the Earth.

These images attempt to show three dimensions, so each sphere represents "volume." Overall, it shows that in comparison to the volume of the globe the amount of water on the planet is very small - and the oceans are only a "thin film" of water on the surface.



Large Sphere = ALL of Earth's water
Medium Sphere = Earth's liquid fresh water
Tiny Sphere= Water in lakes and rivers

That graphic of all the liquid water on earth has always puzzled me. It seems much too small, especially the fresh water and river water. It looks like if the bubbles broke and the water spread out it would fill a little bit of space in the United States and that's all. How can those bubbles represent all the fresh water in the world?
