Global Warming Or A Global Cycle? - 11/19/2007 - California Builder and Engineer
verizon.net/mhieb/WVFossils/greenhouse) the following is pointed out: "Just how much of the "Greenhouse Effect" is caused by human activity? It is about 0.28%, if water vapor is taken into account — about 5.53%, if no...Water vapor constitutes Earth's most significant greenhouse gas, accounting for about 95% of Earth's greenhouse effect.

Straw Bale R Values
A major part of this variation may not be due to the straw itself but to the distribution and redistribution of moisture within the wall. Relative Humidity: Warm air can hold more water vapor than cold air. Relative humidity is the percent of moisture in the air compared to saturated conditions. Absolute Humidity: Absolute Humidity is the weight... See #2.

Kelly-Moore Paints - The Painter's Paint Store - (Frequently Asked Questions)
...paint films are less prone to yellowing over time, especially with white, light off-white and pastel colors. Latex paint films are more breathable; they allow small amounts of water vapor to pass through the film, so the chance of blistering is reduced. This is especially important when the surface being painted is slightly damp. Latex paint... See #3.

...consequence of the mild corrosive attack of airborne sulfur compounds - principally stemming from the combustion of fossil fuels. In the atmosphere, these compounds combine with water vapor to form dilute oxidizing acids which react with copper surfaces. As natural weathering proceeds, the metal exposed to the atmosphere changes in hue from... See #4.

Housewraps Weather Barriers and Phantom Leaks
...because their problems have been accentuated by the new and tighter barrier on the outside of their homes. These barriers and house-wraps are sold as “breathable” and water vapor is supposed to be able to pass through. The problem occurs when the cold temperatures condense the air and moisture becomes trapped behind the barrier. See #6.

What A Regenerative Dryer Is, Presented by Sahara Air Products
Virtually all free air contains water in the form of water vapor. We call it humidity. When air is compressed to 100 psi, the water vapor is concentrated to about 8 times normal! Water vapor is no problem in compressed air until temperatures drop and condense it into droplets of water. Then it combines with any... See #11.
