John,
I see your point that there must be some effect from emisions and polutants being dumped into the atmoshere, but I disagree with you that it's having an effect on the planet in a measurable degree.
From a report on CNN, they said global temps have risin 1 degree in the last hundred years. If we go back five hundred years, theres very strong evidence that the planet has be warming since the 15th century. So for the last five hundred years the planet has been gradually heating up.
In my mind, this lends some credence to the theory that global warming is a naturaly event.
The hurricanes this year were blamed on global warming, but none of them were as bad as the period from the 1030's into the 40's. This tells me that it was worse back then when we had much less effect on the planet. What caused that decade of really bad hurricanes if it wasn't influenced by man?
My thinking is it's a natural cycle that happens over decades.
Here in Texas and much of the south we're experiencing a drought and unseasonably dry temps. So far we've had one day that broke record highs, but we've also had one day that broke record lows. Most of the record high times are spread out from the 30's and 40's.
Seems that these things go in cylces and since they have been happening for hundreds of years, it's hard to ignore them back in history and only blame the recent ones on polution and emmisions.
The Northwest is getting allot of rain. Will it break the record? I don't know, but if it does, that doesn't mean it's from something man has done, just that the cycle of dry weather down south has affected the wet weather up north.
Recently in the news it's been discovered that plants generate heat by holding temps on the ground after the sun sets. The more forrest we have, the longer the earth takes to cool off. Trees have more of an effect on planetary temps than cars!!
If you dump a glass of water in a lake, it will affect the water level, but is it noticeable to the overall lake? Nope. I believe the same is true with the planet and global warming.
Just my thoughts on the topic,
Eddie
