carbon bubble: In the case of the dotcom bubble, it was that we could have unending exponential growth in IT sales, according to The Toronto Star. In the case of the subprime mortgage bubble, it was that securities funded by mortgages of unemployed people should be as credit worthy as government of Canada treasury bonds.

If you look at the Blackrock iShares Oil Sands Index ETF, which is an exchange-traded fund that covers all the TSX-listed oil sands producers, it has lost about 70 per cent of its value since early 2011. That view has become increasingly challenged by the link between what we emit and the climate change we’re seeing.Q) Has the carbon bubble already burst A) For all intents and purposes, the bubble has burst.
