I believe in taking science seriously- but just with a grain of salt. After all, I still remember when global cooling was a threat to our future. I am not sure that recorded human history is a long enough observation period to make conclusive statements about the human contribution to climate change- given the vast swings in climate the earth has experienced in its billions of years of history. Nevertheless, I believe we should do everything we can to be stewards of this planet. I also support doing what we can without taking food off anyone's table(bio-fuels). We also need to make the changes without putting folk out of work, increasing the cost of living, or exporting more jobs overseas where there are light restrictions.
