More on the dash for gas

A few weeks ago I commented on the "dash for gas" and speculated a little on possible arguments in favour of it. The following quote from Kevin Anderson of the Tyndall Centre for Climate Change Research puts those speculations into perspective. He says:-

"We are heading towards a global temperature rise of 4C to 6C this century; if we want to get off this trajectory, shale gas needs to stay in the ground and we, in the wealthy world, need to consume much less energy - now."

 There seems to be an issue to be resolved here between Kevin Anderson and Dieter Helm.
