To be fair they would though. It's like saying that the authority on the question of "Does god exist?" should be priests because they are the 'experts on god'. Yet they also clearly have a vested interest in the answer being yes.Almost every scientist who studies this stuff would disagree with you. I know who I choose to believe.
I'm not a climate change denier/sceptic, I'm just pointing out that personal vested interest often stands in the way of the truth and/or progress. See the train strikes a while ago where one of the demands from the staff was 'no moderinsation on the railways'.
No one will make themselves redundant.
