also i rember recently, that it appears to be that the "greenhouse gasses" and associated haze in the atmosphere is actually helping to Cool!!!!!! the planet!!!!!!
Errrr.. You kinda got it half right.



Global Warming vs Global Dimming.

Airbourne particles associated with burning fossil fuels (smoke etc) is reducing the amount of sun's energy reaching the ground (from 9-30%) through directly blocking sunlight reaching the ground, as well as creating more nuclii from which clouds can form. More clouds mean more sunlight being reflected back in to space.

This was indicated by the reducing rate of water evaporation at meteorological weather stations around the entire globe.

This has meant that the effects of CO2 has been underestimated. The models up until now have not taken the effects of "Global Dimming" into account.

As emitions become "cleaner", such that the amount of visible airbourne particles associated with combustion reduce through better engine design etc while the levels of CO2 emmisions in the main don't, Global Warming is now expected to accelerate at rates no current atmospheric model would have predicted as global dimming was not a considered factor when measuring the current rate of global warming.

By the way does anyone understand why they call it "The Greenhouse Effect"?
The same question would be "How does a greenhouse work."

so on the Bigger scale of life, there is NOTHING we can do on this earth to protectus us and prevent the events of ultimate reality.
So what are you saying. That we should all just carry on and not care about anything?
