No, they don't, nor do they, like most people, understand it.
However, I left out a key word in that. It should be long term DELAYED downstream causality. You can infer causality with considerably better confidence (better than zero, that is) if the effect happens immediately after the causal agent. After all, chaotic systems are oscillating around an irregular space known as the strange attractor. If you shift the strange attractor, you will see the same oscillations, but around a different location. The point behind climate change is that people feel that the strange attractor has been shifted.
In other words: There has always been long, short, and very short, cycles of temperature fluctuations. There are record colds, extreme colds, cold, warm, extreme heat, and record heat. These always happen. Eventually, if the strange attractor never moved, there would never be another record set, though that could take infinite time. With global warming, there will still be the oscillations that we have always had, they will just be oscillating around a different point (actually not a point, but you get the idea).
So global warming doesn't violate what I MEANT to say, had I not left out that one word, but that doesn't change the fact that very few people seem to both understand chaos, and accept the implications. Some understand it, and choose to ignore the implications as far as causality is concerned, while the vast majority don't even understand it.
