Have we overlooked that like art climate change could evolve in a non linear way?!

Are We Moving into Another Era of 'Abrupt' Climate Change? : TreeHugger

Its a scary, but nonetheless none too surprising expression of opinion that we could be experiencing global warming and climate change right now with impacts that are uneven and evolve both subtle ,dynamic...but also quite dramatically.Modelling apparently shows us that it could not be random non humanly affected events...or so is said ...regardless any scare that motivates and informs us further is good in my opinion in moving us in positive directions and along a more sustainable, though scarier and less certain path.
