Default Global warming? "Evidence" from my garden?

1. A have a lungwort that normally flowers in spring. It's just sent up
a couple of stalks with buds on them
2. I have a Cyclamen Coum in flower (no leaves)

Is that really enough evidence for an indictment?

Oh, God, not cyclemania again :-( As with most other areas where
people have claimed to discover cycles (and the reason is not
obvious), there is damn-all evidence for them. Most of the time
the series is almost certainly an ARIMA model of sorts (think of
that as a correlated random walk).

I'll say this for it, though: pdq does mean "pretty damn quick".

That is true, but is seriously misleading, because there is a LOT
more data of adequate quality - if you are up to handling it.

If you're of the opinion that your conjecture is superior to that
of the meteorologists whose opinion I quoted then good for you.


No, my statement is not conjecture. I am a statistician,
incidentally.

To repeat what I said, there is damn-all evidence for a cyclic
phenomenon in this case and, in situations like this one, almost all
cases of apparent cycles are created by something like an ARIMA
process. I could also add that the observations from previous
centuries are quite good enough in quality to debunk the theory
that there is a single predominant cycle.

While I am pretty rusty in this aspect of statistics, I could still
explain in more detail than I expect you want to know about this
issue.

All else is hand waving IMHO.


There is one thing for sure - it's going to get a whole lot hotter around
here in 6 billion years or so.

And you are regarded THAT as being an ACCURATE representation of
what he said? Have you NO experience of how scientific statements
get mangled in the press?

Professor Saunders says that the current situation is a result of
natural climate variability. Drought trends going back more than
100 years show this sort of natural cycle repeating itself time
and again. He also rules out global warming as a contributing
factor since it is expected to cause wetter winters.


And there you can see it. Assuming that he knows his statistics,
the first sentence is likely to be an accurate representation of
what he said, but the term 'natural cycle' was almost certainly
introduced as a loose description by the reporter.

I'm not in the habit of posting unsupported rubbish on NewsGroups


Then please don't do so again.

Variously it was written:

Quite. I favour Velocette, but others like Triumph...


I read on teletext today that some ladies are cycling around england on
Harley-Davidson bikes.

I wasn't aware that they made bicycles!
Alan


I wasn't aware that they made bikes !
( motorised armchairs, more like)
mallards

Bring back my trusty Comet and Rapide ,, I wish,,,,sigh,,,

PS Those ladies must have strong legs then, not to mention the thighs
and,,,
