I don't disagree that finding alternative fuel, reducing polution etc is not a good thing.
There has been too many outlandish claims made by the AGW believers to be credible. These claims completely devalue their argument. The claim that the debate is over sounds like a petulant child that is trying to protect a lie.
The very fact that the science is not conclusive means the debate is well and truly NOT OVER.
The outlandish claims of 100m sea rises etc are complete bull **** and designed to scare people into believing something that has not been proven (just like your claim of houses falling into the Swan River). Many natural events are being claimed as a result of AGW that are just not true. The argument that we should be acting NOW etc. just in case its true is also a scare tactic. So that when it doesnt happen they can claim success.
Even if the world warms by 2 deg there will be many that benefit from warming. 2 deg rise will not melt the poles. The effects of AGW are grossly over estimated to scare people into action.
If the AGW believers were more open to view and debate the science and be more realistic in there estimates etc. they would have more credibility in my book. Until then it is just a theory yet to be proved or demonstrated to be anything other than a normal natural event.
