Have you heard this theory? That global warming could be attributed to sun spots? In other words, it has nothing to do with us humans....with our 'polluting' ways. (Even if this is true, I think we should still clean up our act.)
At any rate, I was reading that back in the 70's (before my time) they scientific community was actually calling for a mini ice age. ICE AGE??!!! What a dramatic change from the news of today.
I found a few different articles on the subject, but not being a scientist most of them were way over my head. If you want to read one that is written for the common man, read this one by Enric Palle Bago when he was a doctoral student at Armagh Observatory. It is an easy read and does a pretty good job of explaining things in a way I can understand.
The evidence to support that our current warm climate is relatively normal is good news. That means our self destructive, earth polluting behavior is not the only culpurate. (Though it is probably speeding things up...)
So I am back to square one in my thoughts. Are humans causing global warming or is this a normal cycle and regardless of that answer, can we clean up our acts to preserve the Earth in a way that not only saves the environmnet, but makes economic and political sense?
