Global Warming is happening

[Madaya]

Look, I aint a greeny or similar, just a plain old bloke like yourself. I've spent the last several years trying, and sometimes finding, holes in the Global Warming argument.
The last several months have swayed my opinion. It is real, it is happening. End of the World = No. But big changes will have to happen, driven by climate and rising sea levels.
Okay, so the data is in (doesn't matter whether you are Labor or Liberal at question time).
From what I have researched = the following...
CO2 (Carbon Dioxide) as well as CH4 (Methane) absorb Infra Red light. This is predominently supplied by the Sun, but a small fraction is supplied by us. When I say absorbed, this basically means, they retain the heat (energy) imparted to them, hence warming the particular enviroment they are contained in, i.e. the Earths Atmosphere.
How to fix...
A friend once showed me a series of graphs, concerning absorbed and reflected light (heat).
Bottom line was that if everyone built or painted ther house roofs with 'white' paint (I guess off white is okay), and world wide, it is a lot of houses, we may well be faced with Global Cooling. The reflected light would bounce back into outer space and not interact with our atmosphere.
A black, or dark roof, absorbs light, and emmits Infra Red (heat), ready to be gobbled up by CO2 and etc.
What astounds me, is the number of newly built houses that have black or dark roofs. Mate, this is Australia, you want to reflect the heat, not draw it in. This works in reverse in what we used to call winter. The light coloured roof, reflects heat back into the house, keeping you warmer. The black roof is an open radiator to the atmosphere.
