The problem that I've had is this. When I was much younger, my grandmother exclaimed that eating the outside of a potato was unhealthy. She had scientific studies backing her that it was bad for your health. A couple years go by and she then states that the scientists claimed that eating the skin of the potato was the ONLY healthy portion of the potato. In other words, the complete opposite of what was once believed. She later changed this again, stating that eating all parts of the potato were okay, so long as done only in moderation (imagine that... moderation). I've heard similar science about the egg. Are you supposed to eat only the yolk? Or only the white part? Eat all of the egg, but watch how many you consume? Seems that even within the scientific community, there are those who are for and there are those who are against. If those doing the science can't make up their minds, why is it wrong that I continue to disbelieve?
I understand that there is global warming. I also understand that there is global cooling. There's that whole cyclic thing going on. What I have a hard time swallowing is that those claiming global warming is due to humans refrain from modifying THEIR behavior, while exclaiming its MY responsibility to change mine. Why is it acceptable for Al Gore to travel in his jet? How does paying someone else (who doesn't have much C02 footprint to begin with) prevent this global warming due to humans? That is what I cannot grasp. Please, someone explain to me this. As explained by Pat Sajak (of all people, I wouldn't have expected Pat!) in the link provided by Attila Dimedici, why not set the example rather then pointing the finger everyone except yourself?
