    Drink Cars enhances more lives than the deaths it causes.

    Taken (the above bold print) from one of your pointless moral speeches to justify the use of alcohol. See where your moral compass loses its way yet boyo?

    Less traffic, fewer pedestrians and cyclists = higher safe speed.

    Can you stop safely on your own side of the road in the distance you can see to be clear?

    That is how you determine if your speed is safe.

    You'd need to rebuild London Bridge as was, its impedance to the Thames's flow coupled with a mini ice age caused the Thames to freeze over.

    There is indirect evidence that the gulf stream switches off periodically maybe circa every 1000 years. We may be speeding it up or still coming out of the last real ice age and speeding that up as well.

    Cars - many people are probably currently driving about as far as they will be able to when pure electric cars come - not very far at all.

    I do realise we have cycles, and the world slowly changes temperature, in my life I can remember some hard winters, the summers tend to forget, but if I considered hardest winters, seem to be around every 11 years, first one I was around 6 years old, last around 7 years ago, but at 6 I went out and was able to push my way through the snow, the one 7 years back as a 6 year old I could not have moved, so over my life personally there is little I can see which shows warming, OK the council no longer has a snow blower, but never remember them using it anyway, after some one fell in it they fell out of fashion. And better weather forecasts means the snow is tackled before it needs a snow blower, the snow 7 years ago did need one, but roads simply not cleared.

    We did not have a bus service for 3 weeks, 7 years ago, that never happened when I was a lad, even deep into Wales, within a week roads open, but was that because council had every local farmer pushing a snow plough, or because the snow was not as heavy?

    All through my life there have been odd weather conditions, I have seen flooding where you would not think possible, on the side of a hill where the water entered back door of house and exited at front, never happened again, it was a freak, earlier this year Shrewsbury flooded, wanted to see if daughter OK so went to look at pictures, computer picked up old black and white photo, had it not been black and white I may have thought this year, but when I looked at date is was early last centenary and guess what, water was higher than this year.

    Those old enough can some times remember things not shown on the news, Mold floods are today worse than they use to be, however reason was the building of Shire hall and other buildings on that hill produced a lot of waste earth which was dumped on the flood plain, and it was made into a rugby pitch, so now no where for water to go, nothing to do with more water.

    I am sure there is globe warming, but each time one sees something pointed out as being a result of the warming and you know it has nothing to do with that, you start to wonder how many more are the same, all that coal was once CO┬▓ in the air, making the air denser, so animals could fly then which could not fly now, today's rubbish in land fill will likely be tomorrows fuel.

    The problem is not change, but speed of change, so if we make a big push for diesel then find it's not that good, by time we find out there as too many already made, I will guess we will find a problem with electric, we have seen where one car took a week to put out the fire when crashed, can you think what would happen with a motorway pile up of electric cars. Does not bare thinking about, we did not use North Sea gas for cars because of safety, but we are going to use electric? Even petrol, specially non leaded, see how it burns compared with diesel, there is more than particular emissions to think about.

    We are assess the risk, and should select the lowest, so watch a plumber at work, to use non leaded solder you need a flux which is rather nasty, however for potable water you don't want lead, so fair enough, but for central heating unless you set up extractor piping before starting the fumes are really nasty, are you sure those fumes are better than the lead they replace?

    I was working alongside a plumber the other week and he crimps all his joints

    The earliest flooding in the midlands I can remember was put down to land drainage also mentioning that this had the side effect of washing more soil into the rivers. Also building on flood planes. This mostly relates to the Seven. B'ham has suffered at times because what might be called large streams get buried and piped so that the area can be built on. They are often used to carry rain water away so the more areas that get built upon the more they have to carry away.

    Same here. Went out at 8.30pm for my proscribed single exercise of the day. Traffic fumes were undoubtedly much less as hardly any traffic around. But I couldn't tell if it was any better because of the people using log burners and maybe bonfires - but mostly log burners I believe. The stench was far worse than traffic fumes and my clothes stank of smoke when I got home. Also one clown down the road drives a Toyota Pious, but has his log burner going all winter.

    It seems that when we curtail one pollutant, people adopt another. Something similar happens with tree-hugger energy savers like light bulbs. LEDs consume a lot less power than GLS and halogen - but people have many more of them. Many places lit up like Blackpool illuminations. My brother had two light fittings in his lounge with three halogen GU10s in each one. After he refurbed, he now has 18 LED downlighters in the lounge. A neighbour's lounge has many more - looks like the ceiling of the London Planetarium. What's the point?

    The Dee and Seven can both be controlled, there are dams which as long as Vyrnwy is not kept full then flooding can be avoided, but the people who control levels are not the same people who control flooding, so they keep it full rather than half full so no room when needed, also it can dump water in Seven or Dee but at the moment they are not allowed to dump in the Dee so it needs the government to nationalise water again.

    There is a simpler view of the pole icecaps that has puzzled some pretty famous people for a long time. Why isn't all of the water there? Sound stupid but they are so cold that any moisture in the air that gets there freezes and drops out leaving extremely dry air. Winds circulate air all around the globe.

    The gulf steam is maintained by cold poles and warm seas at the equator.

    Put the 2 together and it seems some natural cycle maintains something similar. High sea levels at one end and ice ages at the other.

    This doesn't knock climate changes down to us theories though.

    In the 70's the concerned were warning about deforestation and that it would cause shifts in weather patterns in general. Rain forest for instance is called rain forest due to the amount of rain there - that is a side effect of the forests. There are some interesting theories about what the long ago deforestation of Europe did - Sahara and others changed as did the monsoons.

    :eek: We as a species are in trouble. In fact many think that the civilisation developed during an unusually stable climate period.

    Yes but they also give out heat, so unless that heat is not required it is not waste. In summer yes waste, but in winter radiant heat means the air temperature is reduced so in real terms they save energy as the air temperature can be reduced.

    There was an announcement fairly recently that led bulbs had made the uk greener more than anything else that had been done just by our increased use of them.

    :) Maybe some one should have calculated the increased use of gas in gas heating systems. Some led bulbs also last a lot longer than some others - another factor, they don't grow on trees and have to be made.
