We are indeed experiencing global warming, but what is misinterpreted is this having to do with man’s actions on the surface of the earth.

Global warming is cyclical. Every 275,000, to 300,000 years, our inner core of revolving molten iron, and rock, which generates our electromagnetic shield around the earth, starts slowing, and then stops. When this inner dynamo slows, and stops, so does the electromagnetic shield around the earth which protects us from solar rays, the sun’s radiant heating, and cosmic rays.

Geologists have pulled earth core samples of magnetic rock, and these samples show a slowing, and then reversal of the magnetic fields in magnetic rock, occurring in long-period cycles as mentioned at the start of my comment. This is happening now and has been for some time.

Our electromagnetic shield around the earth is diminishing, and after a period of time, will stop, before another long period, after which it will spin again, but in the opposite direction, causing compasses to point south, and not north in the future.

While we are examining causes like cow farts, emitted gasses, etc., the real reason is being overlooked, and that will have serious consequences, for how are we going to survive when there is no longer an electromagnetic shield around the earth. This will have a catastrophic effect on all life, as well as living organisms, and plant life. We need to disengage our thoughts from man being the cause, because this has happened before here on earth when man had barely an existence, let alone industrialization, deforesting, etc.

We need to avoid the political, and social views, and focus on survival now. The sooner the better.
