Ever since planet Earth was created about 4.5 billion years ago, it has been exposed to natural processes and forcing mechanisms within the solar system and earth. During the course of millions of years, the interaction of these processes has implemented a natural climate and planetary rhythm.  These rhythms include but are not limited to:  day and night, the four annual seasons and weather events during the particular season, short-term climate fluctuations and oscillations within the seasons, and long-term climate change cycles such as glacial periods which occur approximately every 120 thousand years.


The gravitational cycles of the moon and sun cause the seasonal tilts of the earth's axis and the 4 seasons.  The strong gravitational pull of the moon causes a bulge to form in the center of the 5 oceans.  As the earth makes a complete rotation on its axis daily, the moon rises and falls in the sky.  This causes dramatic changes to the gravitational pull, with increases and decreases occurring during the daily cycle.  This causes a gravitational pulse which in turn causes an interactive plunging action on the ocean's bulge, thus producing the twice daily ocean tides. The gravitational tides are also noticed in the earth's atmosphere, and in lower depths of the ocean.
​

The daily rotation of the earth provides the twice daily tides, and the 27.5 day elliptical path of the moon around the earth provides a monthly and bi-monthly  gravitational pulse.  The cycles then extend out in time as the elliptical path of the earth around the sun, and the moon around the earth cyclical change from one month to the next, every 6 months, 4 years, 9 years, 18 years and beyond.  The earths 130 thousand year elliptical path is well documented in science and is proven to be the cause for the earth's inter-glacial (warm) as the earth swings in closer to the sun, and glacial periods (cold)  that occur every 130 thousand years as the earth swings further away from the sun.  The current warm inter-glacial period peaked about 7 thousand years ago, and the peak of the next glacial period will be 70 to 110 thousand years from now.
​
The earth's climate is very complex and very cyclical due to the PFM Natural Climate Pulse interacting with the oceans, atmosphere and inner/outer cores of earth.  The high and low tides of the oceans alternate approximately every 6 hours, and ocean tides and some currents change with the PFM cycles.   Above the surface of the Earth is the atmosphere which is made up of nitrogen, oxygen, water vapor and other gases which move fluidly around the planet.  The flow of these atmospheric gases are caused by the rotation of the earth, heating of the atmosphere and ground by the sun, proximity of mountain ranges and water bodies such as oceans, and forcing mechanisms such as gravitational tides caused by the PFM cycles  
​
Earth's temperature changes seasonally due to the seasonal tilt of the earth, with longer term cycles due to the PFM Natural Pulse cycles every 10-years, 230 years and 130 thousand years. Carbon dioxide concentrations are a naturally occurring cycle connected to the short-term global warming cycles that occur approximately every 230 years, and the longer term 130 thousand year glacial and inter-glacial cycles. The eBook written by Mr. Dilley of GWO (avalable on the Natural Pulse Page) illustrates that earth's current temperatures and carbon dioxide levels are perfectly normal for global warming cycle that was occurring up to the year 2012 (now beginning to slip into global cooling for the next 150 years).
