It's not my fault.

The global climate is changing, but you can't lay any blame on me. It has always changed, from way back before I was born. Sometimes it gets really hot. Sometimes it gets really cold. Sometimes the change comes quick. Sometimes the change drags out over millennia. This is what the data shows.

And another thing: everyone is all atwitter about carbon dioxide, but the major "greenhouse gas" is actually water vapor. We're wasting time/money/energy worrying about carbon-dioxide emissions when a small percentage change in water-vapor emissions could accomplish the same net reduction in overall "greenhouse gases."

Of course, that's just if you actually think humankind is powerful enough to change the entire massive ecosystem. Nature is very resilient. When's the last time you didn't see grass growing through cracks in the sidewalk?

What really has me worried is when the magnetic poles destabilize and flip. There's a period of time when we have multiple magnetic north poles and multiple magnetic south poles, all scattered around the globe and moving. If that won't mess up our civilization, nothing will.

The magnetic poles can destabilize and flip???? Has that happened before? How will I know where I am if I don't know which direction is north?

Yup. On average, the poles have flipped every 250,000 years. Then again, they haven't flipped in the past million years, so what do scientists know? The strength of the magnetic field has been quickly declining over the past couple hundred years, which sure sounds like a precursor to a flip. Maybe not for a thousand years, though.

Are scientists theorizing that it was a flip that killed the dinosaurs?
