Think of weather as a large die, with the number 6 signifying a violent storm.
If you add dots to change the "1" to a "6," you've doubled your chances of a "6." But then when a "6" comes up, you can't tell: Is this the original, "natural" 6? Or the "new" 6 that you added? You can't be sure. But...

"When I was six years old, there were conflicting theories about how babies were born. Somebody said a stork brought them. Another guy said your parents bought them at the hospital. Another said girls had some kind of flap between their legs that babies came out of, and something about penises.

In earth's past, CO2 rise lagged temperature, so CO2 can't possibly cause global warming? This is like saying "'I saw a chicken lay an egg. That proves chickens don't come from eggs.'"

Models are unreliable. I agree -- they are often late for photo shoots, and sometimes never show up at all!

Future generations "will reproach us, not for what we have used, but for what we have wasted."
—Pres. Theodore Roosevelt.

What does "more intense precipitation" mean? It means that, in the immortal words of the Morton Salt Company, "When it rains it pours."
Category:Oil & Coal Dependency
Using oil, coal, & natural gas for our energy is as if someone said, ‘let’s build a civilization on dinosaur bones.’ Somebody else says, ‘dinosaur bones! I am not sure how many of those there are.’ Then someone responds, ‘Oh, Yes! There are lots of them out there. Let’s just do it.’

Renewables too expensive? Navy Secy. Mabus: "Every new technology is more expensive. What if we hadn’t started using computers because they were more expensive than typewriters? What if we hadn't started using cell phones because they were more expensive than land lines? Where would we be?"

"Mother Nature is just chemistry, biology and physics. That's all she is. You cannot sweet-talk her. You cannot spin her. You cannot tell her that the oil companies say climate change is a hoax. No, Mother Nature is going to do whatever chemistry, biology and physics dictate"
