A scientific study of the affect of humidity on daily, monthly and yearly temperatures.
Water Vapor Feedback - Is it positive or negative?
“An essential element of the “greenhouse effect” hypothesis is the positive “water vapor feedback” hypothesis. That is, if something causes an increase in the temperature this will cause an increase in the evaporation of water into water vapor. This new humidity will absorb more of the infrared radiation coming off of the ground. This increased absorption of infrared radiation is believed to warm the air even further.
This makes the air able to hold even more water vapor and this result in even more evaporation, which increases the humidity even further and the cycle starts over. This is called a “positive” feedback, since water vapor is believed to amplify atmospheric warming. Being curious about the truth of this hypothesis I designed a simple experiment to study the effect of rising and falling levels of humidity on soil and air temperature and discovered that 1) the addition of water to a climate system exerts a significant negative feedback against temperature changes night and day, 2) water vapor has the same graphical relationship to temperature that insulin has to blood sugar and insulin is known to exert a strong negative feedback against blood sugar levels and 3) over the course of time the addition of water to a climate system causes a perceptible drop in the yearly mean temperature.”
