I can't believe how much misinformation and just plain c*@p some people, will spout.
And I am not going to fully explain it at the moment because I'm watching the F1 qualifying, however here are a few points.
The Oceans act as a carbon dioxide sink, they absorb CO2 from the atmosphere yes, but only up to a point, there is such a thing as over saturation of the oceans.
The absorption rate of CO2 in water decreases as the temperature increases, therefore with the potential and most likely probable increase in temperature due to the enhanced greenhouse effect, i.e. less latent heat leaving the upper atmosphere due to the increased absorption by atmospheric CO2, methane and water vapour, this will cause the ocean to emit CO2 adding to the human impact.
Coal, Oil, all the underground fossil fuels that acted as historic carbon sinks, these fuels are the ones currently being burnt by humans for anthropogenic uses. This is why, since the industrial revolution, the atmospheric carbon dioxide has almost doubled over baseline levels.
These are the facts, none of the bulls*t fear campaign as often cited by politicians.
People are always going to make up their own minds, but I honestly can't believe how many otherwise intelligent Australians get caught up in politics and the Liberal vs Labour debate instead of good policy vs bad policy.
