That leaves a 5% chance that we're not.

There's a 95-percent chance that humans are to blame for global warming.

"The 'fingerprints' of human influence on the climate can be detected not only in rising temperatures but also in the saltiness of the oceans, rising humidity, changes in rainfall and the shrinking of Arctic Sea ice at the rate of 600,000 sq km a decade."

Of course, scientists are still trying to convince folks that global warming even exists, much less that we might have had a hand in it. "Oh, look. It's snowing outside my window, so that proves that Al Gore is a crazy crank."

With my freckles and fair skin, I hope to be dead when the planet teaches us the difference between anecdote and data.
