More to do with the north east wind that has been with us for the last couple of weeks.

The Icelandic volcano (Northwest of England) isn't large enough to pose any real threat to us Paul.

could they not just put a really big cork
over it then when it blew it would hit the cork and go downward
and all that ash end up on the Aussies - they done grow much
and therefore food supplies aren't threatened
Just need a bit of thinking through

I see the ashcloud is now affecting parts of Portugal,Spain and France,among others,and causing disruption to flights etc(we have our own disruption called Unions!)
The problem is that this could go on for years and although the wind will come from the South West in the main and push the cloud away,any change back to North/North-west will bring the ash cloud back if it keeps on erupting.....
Lord Paul....they would still beat everyone at cricket!!

No sun
If that volcano keeps erupting and putting ash in the air for a long time; it will filter the heat of the suns rays and lower the temperatures. Ice age anybody! Have to dig out that wolly Mammoth skin coat Ive got somewhere.

Warm clothing, a good double skin bivvie and an arctic-proof sleeping bag may well be good investments...
Europe on ice...

Like that on Ed, very droll. Since the smoking ban theres been a huge ash cloud outside every pub doorway and now the pubs are becoming extinct. Might be something in it afterall.:w

Let's just say that when the next big one goes off, we won't be here worrying away at about article-theft, choice of reel or otters etc - not for long, anyway...

Never mind 'going the way of the dinosaur', having spent a few days trying to escape from Spain I know what it is like to be treated like sheep! Be warned, if you travel with a low cost airline like Easyjet you get treated like *****.
Having said that, it was nice to spend some time looking around Madrid.

You might need a warm cardi' when sightseeing (or cancel your travel plans) if something like this happens again -
Year Without Summer: Effects Of Tambora Volcanic Eruption On Iberian Peninsula Studied For First Time
ScienceDaily (Feb. 26, 2009) — An international team of scientists has presented the first-ever evaluation of the impact of the 1816 eruption of the Tambora volcano in Indonesia on the Iberian Peninsula. Historical documents and observations by Spanish and Portuguese stations have shown that emissions of gas and particulates from the volcano limited the effect of solar radiation in Spain, where temperatures that summer did not rise above 15ºC.
The Tambora volcano in Indonesia erupted in April 1815, but North America and Europe did not notice its effects until months later. In 1816, known as "the year without a summer", gases, ashes and dust arrived over the Iberian Peninsular and reached the stratosphere, where they remained long enough to create "an enormous sun filter".
These are the findings of a study by an international team, with Spanish participation, which have been published in the latest issue of the Journal of Climatology.
The researchers have studied, for the first time, the impact of this atmospheric phenomenon on agricultural production in the Iberian Peninsula in 1816 and 1817, and have evaluated and compared the climate in the area with that in 1871-1900, before it started to be affected by climate change.
"The year 1816 was characterised by great anomalies, especially in the summer, which was much colder and wetter than usual. In Madrid, temperatures were below 15ºC in July and August, and that Autumn the Catalan peaks of Montserrat and Montseny were covered with snow and the Llobregat river froze over," Ricardo García Herrera, one of the authors of the study and a researcher at the Complutense University of Madrid (UCM), tells SINC.
Baron Maldá's diary
The study includes information from the first instrumental observations carried out on the Peninsula by scientists in Lisbon, Madrid, Barcelona and San Fernando de Cádiz. "It also brings together Spanish and Portuguese documentary sources, such as private diaries (for example that of Baron Maldá of Barcelona), which provide qualitative information about the weather, and religious documents including weather-related prayers," adds García Herrera.
Baron Maldá wrote in his diary that the unusual temperatures in the summer of 1816 could have been related to a "great snowfall" in the centre of Spain on July 16. He also pointed out that it "was snowing considerably" in the Pyrenees and the north of Europe. According to the scientists, this information coincides with the low temperatures of 13.1º recorded that day in Madrid. The apparent snowfall mentioned by the Baron may in fact have been a hail storm.
A bad year for harvests
The eruption of the Tambora volcano was probably "the greatest recorded eruption in historical times" according to the researcher. This is demonstrated by its explosivity index (a measurement of the size of the eruption), which, at 7, "was greater than any other more recent eruption, including that of Mt. Pinatubo in the Philippines", the expert tells SINC.
The consequences of the eruption were noticed not only on the climate, but above all on agriculture. "The low temperatures meant that many crops did not ripen, or if they did their yield was very little and very late," says García Herrera.
The decade from 1811 to 1820 was marked by serious socioeconomic impacts resulting from this poor agricultural production, with malnutrition and the increase of epidemics in Europe and Mediterranean countries. Low temperatures, freezing temperatures in Spring and heavy precipitation between 1816 and 1817 affected the growth of many crops very badly.
The cold and wet summer led to fruits being of poor quality, as well as vines and cereals ripening very slowly, which impacted on harvests. The climatic anomalies were more consistent in Lisbon and Cadiz, showing that the phenomenon in the Iberian Peninsula was not the same as in central Europe.
In addition to the UCM, the University of Extremadura, the University of Barcelona, the University of Lisbon (Portugal), the Lusophone University (Portugal), the Gabriel Pereira de Évora Secondary School (Portugal), and the University of Berne (Switzerland) also took part in the study.

A year without summer Paul? We've just had two of those
Best not worry about the future, just live for today and go fishing. But keep a torch and a few tins of food in the cupboard just in case

Back to the dark ages
Does seem to much of a coincidence though. Geting warm and dry in April; lovely weather and then the eruption and a week or two later as the volcanic cloud gains momentum the coldest weather for years at the time of year. Didnt they reckon something like this happen back in the 600,s (dark ages ) when half the country starved because of a volcanic eruption? Still, us anglers will be alright with our skills at catching fish!
