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 CO² 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?
