Global warming and now global dimming!
Knew all about the green houses and global warming but saw a program recently about global dimming. For those that don't know what it is, the carbon pollutants from burning the likes of gas and petrol emits small carbon particles, these then rise and sit in the upper atmosphere. These particles are actually smaller then the normal particles that would sit and attract water droplets which in turn would forms clouds. The result is that there are far more smaller water droplets forming the clouds, these in turn reflect more of the suns light back into space hence the term global dimming.
Global dimming has in effect been countering global warming but recent changes in emmission laws around the world has meant that global dimming is now receding due to the use of catalytic converters in cars and more filtering of carbon emmissions.
Net result is that all the theories in global warming have not taken global dimming into account and the experts reckon that by 2040 there could be dramatic changes (rises) in the earths average temperature resulting in the Greenland ice caps starting to melt, once this starts there's no going back and things will just continue to spiral out of control.
I suppose if you look hard enough you can find all sorts of doom and gloom stories but there's not a lot the average person can really do but what sort of future is there for the children?
There's no moral to the story but what have I done as an individual? Well I now only use my car when I really need it, walk most places, try to work from home as far as possible rather then drive in and changed most of the bulbs in the house.
