It seems, lately, that whenever I talk to people, they always comment on just how mild this winter weather has been. I am not saying that these people were disappointed, rather, just the opposite. But, having a winter such as this one was, may not bode well with the upcoming summer. A mild winter, without much snow, and a spring without much rain, may leave us high and dry, come summer. What I mean to say is that not all good is dandy. I have not liked the common belief about "global warming" but maybe there is something to that idea. Being uncertain of the cause of global warming, I have hesitated to put much stock into such a belief. However, these last few years have caused me to alter my perspective on such a world view. I am not saying I believe completely in this "global warming" view but I am not going to toss the idea from my mind. Rather, I am going to continue to ponder this view point in the years to come.
I'm no expert, but:
Historically, I believe global warming is cyclic. Melting polar caps cause desalinization of the oceans, slows the currents circulating warm water from the equatorial regions back up to the poles -- causing, of all things, an ice age. The polar regions freeze back up, restarting the engines of oceanic current movement from the equator due to increased salinization -- and, voila! cycles of climate change (perhaps a bit oversimplified).
I wonder how much is caused by us.
There's also a history of magnetic pole shifting, too. That'd be bad.
And -- solar emissions. Geological records indicate those get really deadly.
And -- high speed, very large space materials hitting the earth. Yikes!
And -- there's always the current nuclear arsenal poised for use.
Seems milder now.
