Speculative possibility regarding variations in time of the earth’s magnetic field.
I’ve also wondered if something like the eccentricity of the Earth’s orbit may also explain the swings in the earth’s temperature as in the warming that everyone’s talking about now. Of course that isn’t in 100,000 years swings but still I wonder.
There doesn’t appear to be a question here, so I’ll move this thread to MPSIMS.
For the temperature fluxuations… this cycle of increase is a little faster than the last one… but still nothing out of the orginary.
