Maybe there's a force greater than libs, greater than mankind, that is by far the largest influence on the Earth's weather and climate. Could this force be called the sun ? Meteorologists refer to this force as insolation. Incoming Solar Radiation. In fact, for a very long time meteorologists have referred to this force as the sole cause for all weather. Could it be that simple ? Also, we have another force that may be more powerful than libs. Gravity. This force keeps the earth in a repetitive, and predictable orbit around the sun. Could this phenomena account for changing climate ?
