Global Warming (AGW) - Real or Not

[Zippyjuan]

I was watching "Mysteries at the Museum" last night and one of the segments was talking about Mary Shelley and her writing of the book Frankenstein. It was 1816, and a Indonesian volcano caused major climate change around the world. It was noted in the story as, "The summer that never was."

If emissions from a volcano can alter the weather and the environment, can the emission from human factories also impact the environment?

Is the climate changing?

---Of course, it's always changing.

Are humans responsible?

---To some extent, we must be, simply as a matter of logic.

Do climate scientists know with any certainty how much/what kind of an effect human beings are having?

---I kindly doubt it.

Does anyone know with any certainty that remediation would even be cost effective, relative doing nothing?

---Definitely not.

The last point there is the critical one IMO, and the one most often ignored.

When the climate scientists can make more accurate predictions, so that the economists can estimate costs/benefits, we'll talk.

Till then, this is nothing but rationalization for socialistic policies people want to implement for other reasons.
