Displacing world leaders from their comfort zones

Just read an interesting article about plans for the upcoming UN summit on climate change in Copenhagen [LINK]. Apparently the world leaders in attendance will be stripped of their entourage and be allowed just a single aide. That aide should be their country's environment minister, or equivalent. They will be put into small groups to talk about climate change and its impacts, pairing high-emission countries with those feeling the impacts. They will dine with activists and corporate executives. The idea is to get these leaders out of their political bubbles and force them to think about the effects of climate change in human terms (dare I say in ethical terms?). This seems like a great idea. I wish that the summit were longer, and that this kind of immersion therapy could be extended for several days. Removing the physical and artificial barriers of distance and isolation does wonders for thinking about a topic, and I have some hope that this will spur more urgent action. (Then I'll go back to being cynical when, e.g., the USA congress starts bickering about jobs and fairness and postpones actual action.)
