Before I can fully accept the possibility of Man Made global warming there are a few inconvenient facts that first need to be cleared up..
The main two that spring to mind are these..
Firstly, as I understand it, Humanity is responsible for emitting about 6 gigatonnes of CO2 into the atmosphere every year.
This sounds like a huge amount but when you consider that normal volcanic activity is responsible for approx 150 gigatonnes then it seems that we have a very long way to go to even come close to matching nature.
Secondly, the fact that the records for the Greenland ice sheet over the past hundred thousand years or so consistently show that it is always the temperature that rises first and then some time later, sometimes years, the CO2 starts to rise as well..
I would have though then that if CO2 was responsible for global warming it should be the other way around.
