Re: still going? (@Ru)

"The debate is about whether the changes are natural, or due to human activity."

You state this like it's an either / or question with a simple digital answer: "Nature did it" or "Man did it".

The most likely answer is that it's going to be a bit of both.

However, if Climate Change is mostly natural—and, given the past few million years' worth of evidence, that would seem to be the most likely—I'd like to ask another question: "Should we do anything about it?"

If we interfere with what is primarily a natural process, we would, by definition, turn it into an unnatural process. From that point on, the responsibility for the entire climate of this planet rests on our shoulders as we might divert it too far from its natural course for it to return there on its own without serious consequences during the transitional phase.

I have no quarrel with reducing our species' footprint on this planet wherever possible—pollution isn't exactly fun to breathe, but it is also an indicator of inefficiency in a process. Good businesses generally abhor process inefficiencies and try to keep them to a minimum, so a focus on these aspects makes far more sense than the endless cries of "Wolf!" (Note: probably NSFW).

We don't need these extreme exhortations to get things done. It's incredibly patronising and wins you no friends.
