My comments on the CTV News story:
There's nothing about "climate change" that requires "urgent" action on anyone's part let alone Canada's. The evidence for AGW has always been weak. The recent Climategate scandal showing that key climate scientists have been tampering with data and interferring with the scientific review process makes the scare-mongering IPCC's case even weaker.
The only useful "turning point" will be when our governments come to their collective senses and start to demand verifiable evidence before wasting, or promising to waste, truckloads of taxpayers money.
Update: In the comments Halfwise notes that "Big Carbon", "the Spawn of Enron", was kept alive by Copenhagen. Here's how the carbon markets have been performing as indicated by iPath Global Carbon ETN NYSE:GRN which kicked off at $50 in 2008 and has fallen by over 50% since. Post Copenhagen it dropped from $28 to $23. Note also that volumes are 1000 shares a day or less:
But, meanwhile, if it's a contest in climate la-la land between Mr. Prentice and greener than thou idiots like Charest or Campbell, give me Prentice any day!
