If I hear another word about "Gloabal Warming" I am going to find that al gore guy and slit his neck! 1st off i would like to point out that we are not causing as much climate change as we think we are, 2nd the earth goes through diffrent cycles and such and if there is such a thing as global warming why in alberta up here did we get snow on April 23! Its suppose 2 be 5-10 degrees right now! And 3rd and finaly for all you people that think Al Gore is doing this for the greater good he's not, Do you realise how much $Cash$ hes brought in by doing this. Please think about it, Thank you for reading My Comment. P.S for all of you that have heard about wheat shortages and such think how much of that food is going into these "bio-fuels" I guess some will disagree but those people don't have a brain so, what can you do? Besides they just found out that Sask. Has oil underneath it mabye even more than Alberta.
