Why do you use these weasel words 'climate change'. For the nth time, everybody knows climate changes. If you think there is a simple cause and effect with temperature proportional to CO2 levels then you are simply wrong. Look at the record. Multiple factors make it much more complicated than that. Still, I wouldn't want to spoil a barnstorming speech to rouse the masses.

Suggest you check historical levels of CO2 before sinking into permanent depression.
