For the avoidance of doubt Barry, are you saying that you don't believe that:
1. The increase in CO2 in the atmosphere since the start of the industrial revolution is man made.;
2. That the amount of atmospheric CO2 has increased at a rate far beyond that experienced before the industrial revolution in terms of volume and time scale.;
3. That this increase in CO2 has contributed significantly to the climate change and global warming that the world is currently experiencing? and
4. That this rapid change in climate is having a significant negative effect on the worlds eco systems.
