Any basic astronomy book will tell you that "the mass of an object is a measure of the amount of matter in the object". (Newton)
Newton's third law is a statement of the action-reaction forces at work in the universe. But, as we shall see, the universe is not always in a state of equilibrium!
"Whenever a body exerts a force on a second body, the second body exerts an equal and opposite force on the first body". (Newton)
Now, here is the first of many clues behind possible natural causes of global warming.
"Two bodies attract each other with a force that is directly proportional to the product of their masses, and inversely proportional to the square of the distance between them". (Newton)
So. When the mass of a celestial body changes, and the distance separating it from it's neighbors changes … the force of attraction between them changes. Right?
With the above in mind, let's consider the following common event in our Galaxy, and the entire universe, for that matter. Let’s look more closely into some likely natural causes of global warming.
The Birth Of A Star
Enormous cold clouds of gases, called giant molecular clouds, are scattered along the spiral arms of our Galaxy.
Star formation begins when gravitational forces cause a "regrouping" of an astronomical amount of molecules within a giant molecular cloud.
A new star is forming … as if feeds on neighboring molecules!
The mass of the new star increases as it becomes denser. It's mass increases. The more it's mass increases, the more it exerts a gravitational force on surrounding molecules within the giant cloud of gases.
The new star is growing. It is becoming one of the potential natural causes of global warming.
It's gravitational force begins to - impose - a re-equilibrium upon neighboring stars and celestial objects. All objects of our Galaxy are forced to re-align themselves. In doing so, they are forced to accelerate to a new position of equal gravitational force with their neighbors … until equilibrium is reestablished again … for a time.
The basic idea of Einstein's general theory of relativity is that the mass of an object alters the properties of space and time around the object.
Therefore, any celestial object caught within the increasing force field of a new star in formation will, not only accelerate to a new position, but it's properties will also be modified. (More on this below).
The accelerating body will be subjected to - varying - gravitational forces, as it nears, or outdistances, it's neighbors.
Realignments of celestial objects, such as described above, are constantly occurring in our Galaxy, and between galaxies of the cosmos.
Caught Between A Rock And A Hard Place
Now I submit as entirely conceivable that, at times, our Earth can be caught in a "tug of war" between a new born star and it's neighbors. This situation could be the most significant of natural causes of global warming.
As new stars are born, grow, and die, the Earth can be caught in force fields of increasing, or decreasing intensity.
At times, the changing force fields could cause a "temporary" expansion of the Earth's molten lava core. This event could be spread over hundreds, or thousands of years! The Earth’s core temperature will drop slightly, as it expands. The basic laws of physics, governing fluids and gases, are in action here. The Earth’s crust will also cool. The atmosphere, in contact with a cooler surface, will also cool down!
This could be one of the causes behind the "Ice Ages", or colder periods, in Earth's history.
At other times, the Earth could be temporarily "compressed" into a "tight spot" by the new force fields in action, making it's core temperature rise (again basic physics). This rise in temperature of the Earth's core would of course be transmitted to it's thin crust, and to the atmosphere.
"Global warming" would occur, under such conditions. This phenomena could very well be the most significant of all “potential” natural causes of global warming!
Thus, the Earth could, conceivably, be forced into "bouts of fever" of varying intensity, and separated by hundreds, thousands, or even millions of years.
This vying for position between new stars, and surrounding celestial bodies, could be one of the most important natural causes of global warming … and cooling!
I hope I have given you food for thought.
There could be natural causes that lie beyond man's control, or influence!
My Wish And Recommendation
It is generally useful to look at "the big picture" to get a better feel for what might be involved in any problem you want to solve.
Simply because there is always more to any problem than meets the eye!
In the case of natural causes of global warming, or cooling, a multi-disciplinary look into the problem is required.
I feel it is imperative that we, at least, consider the possibility that we cannot do anything to change the course of nature!
Keep in mind that our own star, the Sun, is also caught in the midst of this constant battle of Titans! It's properties are also affected. When our "only furnace" heats up, or cools down, we feel the effects on Earth!
If further research were to investigate the possible effects of the gravitational forces I have briefly described above, we could better understand the natural causes of global warming .
Humanity could then turn it's energy toward finding ways to better adapt to the consequences of changing climate.
