Creating weather

'WE', THANKS to the Government, have been pioneering two significant programmes which I feel are directly transforming our atmosphere and also creating a devastating effect on our weather; specifically, as major contributors towards more rain.

One of these is the result of cleaning up the atmosphere by removing industrial contamination such as coal-fired power stations; this allows the Earth's surface temperatures to rise as the sun temperatures reaching Earth will now be higher; and second, the immense transformation around the world from rural landscapes to urban cities and towns.

The ground surface temperature defines what rain increase/decrease an area will have; the ground should soak-up all the energy (temperature) from the sun.

However, the more we improve the cleanliness of clouds the easier it is for the suns rays to hit the Earth's surface and increase its temperature.

Where rain falls should be random but we find it now concentrates more and more in the same specific areas because there is a direct correlation between clean air and the amount of rainfall and this is also linked to where housing, industry and large solar parks have replaced rural surroundings.

Humidity and dryness measurements are paramount: not many people realise that the Antarctica could be classed as a desert if the air was dry enough!

To get rain we need vapour to condense and to get vapour you need humidity.

Today we have more water vapour in the air rising up into our atmosphere.

At night, deserts cool so no vapour is created from the cold sand and hence no water vapour in the air, whereas in the cities, where the ground has remained hot (urban heat islands) due to the increase in cleaner clouds, the energy is now radiated up.

This in turn generates thermal up-waves, causing vapour to condense and create rain.

In fact, we are creating our own localised weather, threatening far reaching consequences the more we increase the percentage of the world's urbanisation.

If you build a city or large housing developments on a rural area you create a much warmer footprint, resulting in a much warmer effect.

If you now multiply this effect by all of the new housing and industrial developments around the world we end up with a large global effect on climate, even a small cloud can weigh up to 6 tonnes.

We are changing the atmosphere, which in turn transforms the oceans.

Our skies are alive; bacteria is living in dirty clouds and there is a direct link between pollution, clouds and extreme weather.

By cleaning up the atmosphere we allow there to be more hurricanes and in Phoenix, USA, a large transformation from rural to urban resulted in the city being far hotter than the desert, resulting in a distinct change/increase of 12 per cent more rainfall proving the correlation between the two factors.

I think we need to look into these two damaging facts rather than just build wind and solar farms while shutting our eyes to what could be the real culprits.
