Al,

Sorry to disappoint you but I largely agree with SR's scepticism of the article. That the CO2 level has roughly doubled is not in dispute and neither is the heat retention properties of CO2.

Where I disagree with SR and others is:
1 Existing renewables technology is not capable of doing the job. The proof of this is that the proportion of renewables has roughly stayed the same for 40yrs.
2 Killing our economy to reduce emissions more than the rest of the world is idiocy.

It seems that Bob Brown has been 'unpersoned' by the ABC. All other news outlets are reporting the hypocrite's objection to the Tasmanian windfarm and his call for moderation in unreliable power generation, but not the ABC: the same ABC that reported Brown's every word during his anti-Adani posturing. Silence. They are probably very embarrassed
