Roy Spencer on Global Warming

Learn the REAL science behind Earth's climate from Roy W. Spencer, Ph.D.:

We live in an invisible atmospheric sea of water vapor, Earth's primary greenhouse gas. Our atmosphere could hold much more water vapor than it does, which would then lead to a much warmer Earth -- but it doesn't. So, why is the greenhouse effect limited to its current value? We don't know; scientists simply "assume" that it magically stays that way.

Current computerized climate models that predict large amounts of global warming only do so after making very crude and uncertain assumptions about how the Earth's natural greenhouse effect is maintained. In the following article I will explain why I believe that modern science can not say with any level of confidence how much of our current global warmth is caused by mankind without knowing why the Earth's greenhouse effect is limited to its current value.

In the following article I will explain why the answer to this question must be through the operation of precipitation systems, for only they can remove water vapor from the atmosphere. Even though all climate models DO contain the "average effects" of precipitation systems -- this is NOT the same as knowing how precipitation systems interactively regulate the climate system.
