The debate is really how much of an effect it's having.
That's what the debate should be about, but it doesn't seem to go there. To get that going opposing sides would have to venture into the middle ground. There's no milage going there, it's no mans land.
There was a bit on tele a few weeks back where they had an alarmist climate scientist and a skeptical climate scientist. They broke the climate issue down into components:
.Has the CO2 risen due to our emissions?
.Does CO2 constitute a positive forcing on atmospheric temperature?
.Are there things going on we don't know about?
etc.
They had them answer each question on a Top Gear style magnetic board - 100% sure at one end and no idea at the other.
Both scientist pretty well agreed on the facts; or more to the point, how well they are known.
When asked to put a figure on how much of the current "measured" warming was anthropogenic, the answers were 40% and 60%. Not much in it. Of course other scientists would make different estimates.
But for whatever reason, shifting the goal posts on energy has to be a good thing. Shake up the system, get new players into the energy game, clean out the dead wood, stimulate technology. Just as long as the global playing field is level.
