NotWal said..>>>What they have said is that the globe is warming and bad things are on the way. They have also warned us about tipping points, you know run away warming that can't be stopped.
I haven't seen it for a while, but there was also the chaos theory worry that the climate could slip into another "strange attractor" state, which would mean a completely different unknowable planetary weather system.
Chaos theory is interesting stuff, from wikipedia.
Chaos theory is a branch of mathematics focusing on the behavior of dynamical systems that are highly sensitive to initial conditions. Chaos theory is an interdisciplinary theory stating that within the apparent randomness of chaotic complex systems, there are underlying patterns, constant feedback loops, repetition, self-similarity, fractals, and self-organization.Wikipedia
So we are in one "underlying pattern" now created by the current feedback loops. A small change in one of those loops can change the underlying pattern.
One of the predictions is the shut down of the golf stream current buy melting ice, if it happens, this will make Western Britain and Eastern Canada colder for a while. Enough of a feedback loop change? Who knows, it's a chaotic system and the change in underlying patterns is hard to predict.
