I have read and studied from both sides of the argument and have formulated my own opinion based on that. There are holes on both sides of the argument that man is causing it. It's not some definitive science like the lefties want everyone to believe. So I don't believe this man-made disaster theory. Big whoop. I do believe in being a good steward of the earth. These discussions typically end with my liberal friends when I ask them to compare carbon footprints with me. I have solar panels, drive the energy efficient car, etc. But with too many partisan goggled folks it's not about what I do, they just want me to believe in their pseudo-science. It's not happening. So you believe man is destroying the earth? Kudos, must make you feel good. I'd prefer to see action. I've somehow lived through several looming man-made calamities in my lifetime according to science.
