Either today’s students are so completely stupid or else our teachers and educators are totally out to lunch. We already know that history is no longer being taught in our schools but what about science?
It is a fact that we are screwing up the atmosphere and our ecology. But this started on the very day that our ancestors were able to creep out of the primordial slime. It was preordained and nothing can alter the process even if we pissed into the ozone from now until forever. And why not? Because of the Milankovitch Cycles.
What are the Milankovitch Cycles? Duh. Look it up. There are three components of the Milankovitch Cycles which, individually or in unison, will cause our atmosphere and resulting ecology together with our climate to change because they effect the amount and time of solar radiation reaching the Earth. Period. Case in point being the ice ages which occur around every 41,000 years, whether we like it or not.
Can we change or somehow modify the effect of the Milankovitch Cycles? Sure, if we can figure out how to change the eccentricity, axial tilt and precession of the Earth’s orbit around our Sun.
Take the Earth’s axial tilt which is presently at 23.44 degrees. Over a period of 41,000 years it varies from 22.1 to 24.5 degrees. This tilt reached its maximum around 8,700 BCE or 10,700 years ago (the last ice age) and will reach its minimum around 11,800 CE or 9,800 years from now (the warmest point in the cycle) before it starts to swing back over the next 20,500 years to the next ice age. You don’t believe me? Look it up.
In the meantime, over the next 9,800 years, will the Earth inundate itself with the melting of all of the ice thereon? Not if we desalinate the rising waters and use it to irrigate all of our deserts.
Will our going “green” modify the effects of the Milankovitch Cycles? Perhaps a teeny-weeny bit. Maybe. Can they be eliminated? Absolutely not. What can we do?
We can stop procreating like rabbits. When I was a kid the Earth was just shy of some 2,000,000,000 people. Today we have in excess of 7,500,000,000 people and that’s after a few wars in between. This increase is not on a straight line but on a steadily increasing curve. That’s a lot of garbage that we are producing, let alone all of the natural resources that we are using up.
People don’t like to hear it, especially those who are religious, but runaway population growth which is the root cause of almost all of our atmospheric, ecological and climate issues, as well as all of our social problems, will ultimately bring about the demise of our Earth as we know it – not the greenhouse gasses.
Think about it.
