Simply put, there are valid arguments and data for, just as there are valid arguments and data against.
Pro warmers often ignore the effect of sunspots, etc, and the anti global warming side often ignores the fact that CO2 is a known greenhouse gas and the amounts in the air are very high. IMO the single biggest problem with all of this is the cause and effect issue-> Does CO2 cause increased warming, or does warming cause increased CO2? (The answer is yes to both questions)
I have "followed" this topic for years, and I personally am undecided on the topic. Too many unknowns and conflicting information.
With all that said, IMO we should do what we reasonably can to reduce these emissions.
Finally a pretty reasonable person. My only question is who decides what is reasonable? Bureaucrats? Scientists? Al Gore, who is deeply involved in "carbon offset" companies. I am old enough to know I scam when I see one. One of the oldest tricks is to get a sympathetic subject that everybody can agree on, and then use it to make people feel bad. Guilt gets reaction. Of course we all want the cleanest environment possible. I also am not going to feel bad for my lifestyle, not one bit. Sorry.
Why does everybody forget the Earth has been much hotter and colder then now on its own? Can everybody at least agree on that? Who has the authority to determine what exactly is the best temperature for the planet? Maybe the heating and cooling of the planet over time is a good and natural thing? Seems to have worked pretty good so far.
