I have an open mind on this subject, but I insist upon proof. The claims of the global-warming or climate-change fanatics have not been proven by any stretch. IF undeniable proof is presented that the climate is warming, that's just the first step in the scientific investigation. Climate has always changed, and the climate in various areas of the globe has reversed itself time and time again throughout the life of the planet. IF there is warming occuring now, is it a natural occurence? What variables are involved to cause it? How much of that warming if any is human-caused? What constitutues a "safe environment"? The left likes to tell us doubters that we're unscientific. I suggest that it's those who are willing to bet trillions of dollars to reverse a trend that may or may not be real, may or may not be human caused, and may or may not be reversable for any amount of money who are unscientific, not those of us who demand proof!
