I agree. I think global warming is part of a natural climate change cycle.

I read an article on cnn.com about a huge "shelf of ice" the size of Manhattan broke loose, of course due to global warming. It stated that events like this have been happening more frequently in the last decades than ever before in recorded history.

My take on that is, we have just NOTICED it more now because of huge technology advances like satellite imagery, global communication systems, etc. Back in the 1800's, nobody would have known a huge piece of ice the size of Delaware broke off and melted in the sea, causing the ocean to rise 0.0000452".

Only relatively recently(last 4-5 decades) have scientists and tree huggers really taken notice of climate change, and can't accept that it just might be a natural cycle. There is no definitive, rock-solid, conclusive evidence that global warming is happening as a result of mankind.

My $.02.
