Well if you accept the concept of climate change then you must accept
that /every/ weather event is caused by it, on the grounds that the
weather would have been completely different had there been none.

No, every weather event *could* have been caused by it.
Big difference. There is no way of telling what was and what wasn't or
indeed what might have just been excacebated by it.



Yes you can, on the premise that once the flutterby has fluttered its
bys and chaos has spread to the whole system there is nothing that
exists in the system that would have existed had the flutterby not
fluttered.

As an example, we have a low just off Ireland at the moment. That low
would not have occured had the climate been entirely stable the past 50
years. The weather pattern has been so perturbed, that a completly
different low would have formed, or a high perhaps, or a storm. And it
would be in a different position. What is certain is that low that is
there just now would not have been there without Climate Change.

Of course, in theory anyway, it would not have been there if I had not
had that last cigarette some 10 years ago either.

The point is that without Climate Change, none of the current systems in
play around the globe just now would have existed. We would have a set
of completely different different set of systems instead. As such, one
can say that every current system is there as a result of Climate
Change.

This paper:

has just been published where they argue that "the 2012 Arctic sea ice minimum provides a counterexample to the often-quoted idea that individual extreme events cannot be attributed to human influence."
