Maybe one of the things to ask is what would *not* be evidence of

no matter what the weather pattern or weather event, it is all cited
as "evidence of global warming". More hurricanes than normal?
Global warming
coming home to roost. Less hurricanes than normal? Evidence of the
extremes in weather patterns due to global warming. Hotter summers
than normal? Of course, global warming. Colder winter than normal?
Again, evidence of the extremes being caused by global warming.

So, given that everything observed is evidence of global warming,
the
thing to ask the proponents of this theory, is "what evidence would
be required to refute this theory?" When everything is cited as
evidence of a
theory and nothing as evidence to dispute it, then one needs to start
questioning the person postulating the theory.


That is very simple.

If the climate stays the same then nothing is messed up. The exact
local consequences of global warming are very difficult to predict,
but it's very clear that there are unprecedented weather extremes
across the globe already.

For the period we have measurements from.
