Stating the obvious

The BBC, arch eco-activists and pushers of global warming/climate change are at it again. Stating the bleeding obvious.

I draw your attention to the first paragraph;
"The drought that has affected parts of England since June will last into next summer if there is insufficient winter rain, the Environment Agency has said."

True. But then, the sun will definitely shine tomorrow if there are no clouds in the sky.
These days my trust in the BBC's impartiality and trustworthiness has eroded to zero. I don't trust them on climate, I don't trust them on weather, and I don't trust their wild life and nature films.
OK, they were always suspect. When Armand & Michaela Denis made their wild life films back in the 50s they used to piece together the films they had shot in order to create a story. In some ways the only honest wild life film maker was Johnny Morris, who used to put words into the mouths of zoo animals. It was tosh. He knew it, we knew it. It was not a factual programme, merely entertainment.
But then the BBC wild life unit (or whatever it's called) in Bristol got hold of CGI (Computer Generated Imagery) and all pretence of factual broadcasting went out of the window. Programmes about dinosaurs are the worst.
All we know about dinosoars are a few fragments of fossils, yet there they are on the screen in full technicolour and sound. I'm all for using your imagination but these programmes are passed off as fact.....
Now dinosoars are accepted a gospel and don't anyone contradict them.
I do. I am contradicting them and their cronies at the Natural History Museum.

All we know for certain about scientific knowledge is that in time, eventually, everything we take as fact will be disproven. Anyone who disagreed with the church's belief that the earth was the centre of the universe and that everything revolved around it was a heretic. Now we know better.

One hundred and forty years ago the best scientific minds believed that space was filled with a mysterious jelly like substance called "ether". Einstein disproved that theory but was mocked for years by people who thought they knew better.Now we know better.

One day we may know more about evolution, but for now it is only a theory.

Back to the BBC's article. Some parts of the country don't get much rain. Well tell me something I didn't know. This has always been the case. 30 years ago there was talk about doing something about it. Now that successive governments have sold off the water boards who built the reservoirs we rely on, it's going to be difficult to fix. difficult but not impossible.

The rain falls in the North West, but not the South East, where the people live (mostly because it's not raining). The rainwater drains into the rivers and then to the sea. Our Victorian forefathers created a network of navigable rivers and canals that criss cross the country. It is possible to travel in a boat from the North West to the South East by canal and river. If that is the case then it is surely easy for water to be moved using the same network? A few pumps to move the water up the lock systems and a few miles of underground pipework similar to that which links Rutland and Pitsford reservoirs and the water could easily flow.

People keep claiming that the world will run out of drinkable water. Nonsense.
80% of the world's surface is covered by water. Although most of that is seawater, modern technology can easily convert saltwater into fresh.

According to Wikipaedia:
"A typical aircraft carrier in the U.S. military uses nuclear power to desalinate 400,000 US gallons (1,500,000 l; 330,000 imp gal) of water per day." A big ship with a large crew floats in sea water and converts sea water to fresh water as required. We are an island surrounded by sea. Why not convert sea water to fresh?

There are several methods of desalination, but two that spring to mind are:
Multi-stage flash distillation which accounted for 85% of production worldwide in 2004; and processes that use membranes to desalinate, by applying reverse osmosis technology.
Membrane processes use semi-permeable membranes and pressure to separate salts from water. Reverse osmosis plant membrane systems typically use less energy than thermal distillation, which has led to a reduction in overall desalination costs over the past decade. (Source- Wikipaedia- desalination)

OK so they use a lot of energy and won't solve all the world's problems, but in the UK, an island where no-one lives more than 100 miles from the sea, they could be useful. The nuclear power stations that are sited next to the sea could supply the energy, and an underground water pipeline could move the fresh water to where it can be stored and used.

I envy the Victorians and their "can-do" attitude. If they'd have had access to our technology, they'd have sorted it all out. Everything would have been built to last and not jerry-rigged as cheaply as possible. It would have worked and would have looked great as well (even the insides of the Victorian sewage works- where no-one would see them- were designed to look beautiful).

I'm convinced that there are people in power who want this country brought to its knees. Who want it to fail. Who want it destroyed. 60 or 70 years ago they would be condemned as traitors. Call me old-fashioned, but that's what they are.
