Ah, you have seen the future.
Of course they will not admit they were wrong. The real goal of the AGW charade is to get people involved in liberal activism. Thus, the likely response to the impending global temperature moderation will be along the lines of: "Our efforts have paid off! We have stopped global warming!! If we can make a difference in the weather, we can make a difference in society! March with us comrades!" And expect more 'hockey stick' statistics to demonstrate their point.
Getting people involved is liberal activism is a tool but I don't think it is a goal.
I think the larger picture is indeed a conspiracy of elitists who are promoting global warming as a means of implementing via the UN the 'Law of the Sea Treaty' or LOST. No joking here.

This movement seeks to tie the laws of the world together around the central tenet of atmosphere control. Land use, development, manufacturing and product design will all be under its jurisdiction because 'everything we do affects the air around us'. Therefore, we must be controlled in everything we do.
