Or to put it another way, every action has a reaction, cause & effect
(NEWTON).

So whilst there isn't a little green man at the centre of the globe
flicking a switch, it's amospheric physics caused by an action in one
area of the globe, and over longer periods of time, having an effect
on another area of the globe, that causes the climate to reach a
tipping point and switch, sometimes very rapidly.

I read somewhere that whilst the effects of the globe warming up may
be gradual, sudden switches to a colder climate and its effects can
happen very suddenly.

You are correct according to ice core samples and other proxies I've
always been lead to understand that abrupt climate change can happen
globally very rapidly. I think ten years was one short transition
period I read about. If that was the case then may global shifts do
occur. I think the smooth global transition into ice -age condotion a
staggered with abrupt cooling and periods of warming. Mind you the
bigger the time scales the smoother it looks but human life is over
very small time scales.
