Whether you believe that global warming is man made, or that it is part of a normal weather pattern shift that our world has been through many times in the past I think the evidence of the ice melt all over the world is pretty plane. Our weather patterns have been changing, and they continue to change, more storms, more major shifts from historical weather patterns, stronger hurricanes, more tornadoes. Australia is getting hotter, CO2 levels have been raising. There are definite and measurable signs of the change. Now, having said that, I remember watching a documentary movie in the 1970's that said we were 10,000 years over due for an ice age and it was coming soon. It turns out that the world has been covered with an ice age with some regularity. They happen about every 10,000 years, and we are 10,000 years over due for the next one. If you think about it, all of mankind's advancements, our science, our language and literature, our architecture, our art and music, our medicine, our industrial advancements, have all happened during this last 10,000 years of unprecedented warm weather. If we had been beaten back into the caves by an ice age to stay warm and had to scrounge for our next meal like our distant ancestors we could not have the chance to build the society that we have today. Global warming has allowed us to build what we have today. I will not make any comment as to if Global Warming is a good thing or a bad thing, and I will not make any comment about another ice age being just around the corner [ The last one came on in just 300 years, almost over night in Geological Terms ] Either of these two things could come, and both would have profound effects on us all, and this old man can not change, or even effect the out come one way or the other,
So I do not plan of spending any time worrying about either one of those 2 out comes.
PS I always love it when they get all excited about global warning and say things like " This is the hottest it has been on this date since 1865 ' well, what made it so hot back in 1865 before the industrial revolution and the automobile?
Never doubt that a small group of dedicated people can change the world, indeed it is the only thing that ever has.
