In my local garden centre I saw a very nice climber which had small bluebell
like flowers. I'd not seen it before although it said "grown in the UK since Victorian times". What surprised me was that it said it was "Frost hardy to 2C". I would have called that frost tender. Also, the forecaster on News 24 (Jay?)said that today's rainfall would be beneficial to gardens in the SE and also help the resevoirs. I wouldn't have thought it would make much difference to either if there is only the predicted 5-10mm. Dave |

They probably meant what Philip calls 2 deg. C, in other words hardy to two degrees of frost viz. -2C.

If you compare the area of land not covered by reservoirs with the area covered by them, and assume all the land drains into the reservoirs, then multiplying 10mm by that ratio, I reckon all the reservoirs would overflow :-) Cheers, Alastair. |

But once you consider the limited catchment areas of the reservoirs, and what is lost to evaporation, transpiration by plants, and percolation, then I'd guess that you'd have to multiply in another factor of at least 0.00001. (Or pedantically "at most" rather than "at least", but you know what I mean.) No doubt the water engineers will have done the calculation. Of course, the factor will vary a lot depending on the time of year and the weather. -- John Hall "I am not young enough to know everything." Oscar Wilde (1854-1900) |

Dave Dave, In case the name wasn't shown, the plant is called Sollya Heterophylla and is absolutely beautiful. I grow it in a large pot and just put it inside in the winter. I would call it a tender plant! People in the south west of England would probably have it outside all year. Best wishes Iris McCanna |

Well, if the catchment area of your reservoir is 10,000 times the size the
reservoir, that means it will rise by 18 m. That should be enough :-) Cheers, Alastair. "Keith (Southend)G" wrote in message ups.com... 1.8mm for me at Southend-on-Sea !

Experts doubt that the traditional country garden will survive in the southern counties. The rolling lawns and herbaceous borders that are so much a part of Hampshire, Sussex and Kent may have to make way for palms, shrubs and eucalyptus, while native woodlands of oak, beech, ash and Scots pine from Cornwall to Scotland might be at risk. Experts will discuss the impact of global warming on Britain's landscape at a two-day conference starting today at the University of Surrey in Guildford. They forecast that by 2050 summer temperatures in the south-east will be 1.5 to 3C warmer than today, while average summer rainfall could fall by 35 per cent. If the current rate of warming continues, summers could be as much as 6C warmer by the 2080s. Professor Jeff Burley, director of the Oxford Forestry Institute at Oxford University, said: "It's already happening - you can already see fields of sunflowers. The scene is going to change." _____________________ Martin Dave |

Thanks Iris, I think it would look quite nice as a backdrop to my new pond.
With the micro climate in this south facing corner it might even survive the winter the way things are going. ..... and thanks Keith, I'm sure that will be cheaper than Summerhill Nurseries! Now, back to watering the garden after the 2 mm soaking! Dave |

If the current rate of warming continues, summers could be as much as 6C warmer by the 2080s. I'd be interested to see the mean surface pressure and upper contour patterns that go with these predictions. Warmer and drier suggests an increase in the frequency of anticyclonic southerlies i.e. relatively high pressure over the near continent. That might mean that further east there would be a cooling due to a higher frequency of northerlies. I have no problem with the theory that global warming will result in climate change (and undoubtedly is already) but I have a lot of difficulty in accepting that the subject is sufficiently well understood to enable fairly detailed predictions of the changes that will occur at a spot location (on a global scale SE England is a spot location).
