What would you say if I told you that rainfall is always a good thing, no matter how heavy it is?
You would say I was wrong. You would say that a certain amount of rainfall is beneficial, but that too much of it can be disastrous.
OK, now what would you say if I told you that carbon dioxide is always a good thing, no matter how much of it there is in the environment?
Well, of course, you would be right if you said I was wrong. Yes, carbon dioxide is essential to maintaining plant and animal life on this planet. But too much of it can pollute the environment and cause global warming.
On that latter point, Rick Santorum begs to differ. He doesn’t want to believe in global warming, no matter the overwhelming consensus among climate scientists. Therefore, he’s inclined to scoff at any suggestion that too much carbon dioxide is a bad thing.
Just yesterday, Santorum SAID THIS to a group of presumably gullible admirers in Mississippi:
“The dangers of carbon dioxide? Tell that to a plant, how dangerous carbon dioxide is.”
I’m sure the yahoos in Santorum’s audience cheered his impressive grasp of environmental science. But anyone with half a brain would have had good cause to gasp at such ignorance.
