snipped I have read the link in Alastairs post further down and while
interesting and reasoned science, I am not convinced, mainly because the
temporary cooling began before fusion (H) bombs had been developed and
didn't stop until the mid 1970's, long after atmospheric testing (and
therefore any associated stratospheric pollution) had ceased. As the
article rightly says, fission (A) bombs were simply not powerful enough to
inject material into the stratosphere so there could not have been any
contribution from nukes until the 1950's, if any at all.

Oops, missed the bit about atmospheric testing by France & China in the
atmosphere after the US/USSR stopped. Who knows?

And I guess no mass media to send pictures round the world.

And for what bit of media there was, thankfully, the only thing they
knew about carbon dioxide was that animals gave it off when they
breathed out, plants took it in when they photosynthesised!

I'm not sure that the media have really changed all that much. Wasn't
any unusual weather during the 1950s blamed on testing of nuclear
weapons?

I'm not sure about any specific weather events, the '50's were too early for
me to remember anyway but during a discussion I was having with my father on
Global Warming last year, I did ask him whether there had been exactly
that - any blame put on nuclear testing for unusual weather events then. He
didn't remember any specific ones but did say that there were, as now with
CO2, fears of general climate change if it went on.

The one I do remember reading afterwards was the inevitable link with the
1963 winter and nuclear testing (in a similar way to the 2003 summer and
anthropogenic CO2 induced global warming) but a detailed analytical review I
read on that winter in an old Meteorological Magazine (from about 1968 IIRC)
many years ago concluded with the fact that such a winter was to be expected
as an extreme event very occasionally and therefore no specific cause had to
be linked to it.

I have read the link in Alastairs post further down and while interesting
and reasoned science, I am not convinced, mainly because the temporary

the stratosphere so there could not have been any contribution from nukes
until the 1950's, if any at all.

The cooling did not really start until about 1945, but the late thirties were
the
time of the Geat Dust Bowl. It is possible that the dust from that caused
the cooling from 1940 to 1945. China, France and Israel/South Africa all
conducted atmospheric test after the test ban treaty had been signed until
1976 as explained in that report.

Cheers, Alastair.

I wonder if full account was taken of the unusual number of extreme
rainfall
events which take place just inland of the north Cornwall / north Devon
coast?

Statistically this maybe correct, but stats such as they are throw up
inconsistences. Torrentail downpours in the West Country like what was
experienced last year are not new.
The Lynmouth flood was a masisve one which occurred 50 years ago prior
to Boscastle.
I have also heard that geological evidence suggests that there was a
colossal flood in Devon in the 12th or 13th Century in which over 25 inches
of rain fell. No I am not making this one up. It sounds far fetched, but I
see no reason to disbelieve it either. Unfortunately I cannot lay my hands
on where I read it. I have a feeling that the Royal Met Society Weather
magazine had this in about 3 or 4 years ago.

How did they measure that then Gavin ?,the odd empty mead barrel lying about
possibly,
or how far up a maidens leg as she sank into a puddle........far more
interesting than a Snowden rainguage

It still peeves me when, hearing on Radio news reports " A months worth
of rain falling in a few hours " if im correct 200mm of rain would be
a tad more than one months worth . Im sure Phillip E will concur

Depends where you are, 200mm doesn't sound that much more than months
worth of rain to me. Last year the AWS recorded (approx):

Jan - 75mm
Feb - 35mm
Mar - 25mm
Apr - 35mm
May - 25mm
Jun - 60mm
Jul - 60mm
Aug - 175mm
Sep - 170mm
Oct - 80mm
Nov - 152mm
Dec - 80mm

Bear in mind I serviced the rain gauge in August, it was seriously
under reading before then.

Average August rainfall for the north Cornwall coast varies from around
60-70mm, nearer 100mm over the nearby moors.

The level of fluvial deposits found up a hillside. A good old bit of fluvial
geomorphology. This claim was made only a couple of years ago.
Smiliar assessments have been done in Sweden and Norway.
