I am by no means certain that it is happening.

People who know more than you are pretty certain it is.

The, oh so clever "experts" keep changing their minds about what the
effects are/will be.

As has been said, the experts do not keep changing their mind. There are
many articles published that try to rubbish the research, and by muddying
the research, they make it look like the whole scientific community is in
disagreement.

The predictions are all based on computer models, which are renowned for
their fallibility.

They are renowned for being models. Like all models, they are as good as the
knowledge that goes into building them. The only real true model of climate
change is the Earth itself. We can either try to model what we believe is
going to happen in advance, or watch the real thing play out in slow motion.
There is no argument which will be the most accurate.

However - the evidence for current change is just that - evidence of it
happening now. That has nothing to do with models.

The Gulf Stream is going to stop suddenly, no it is going to slow down, it
will cause extreme cold Winters.

It is slowing down now. There is evidence of that. We will have to wait and
see what it does to our winters in Northern Europe.

If the Winters become extremely cold then will now the Gulf Stream
restart/speed up? I don't know nor do they.

Right, 'they' don't know how easy it would be to start the thing up again.
That's a good argument for not letting things get so far.

By the way in the 1920s lots of scientists and politicians firmly believed
that unless the human race was "cleansed" it would cease to exist because
of bad genes. The cleansing was practised for a while then common sense
prevailed and it was stopped, we are still here.

Are you talking about the Nazis? Perhaps communist dictatorships? Yes, some
pretty nasty stuff has been done by many dictators, but what has this to do
with climate change?
