Most of the speakers had nothing to say so they were emitting the same verbal fog as nearly everyone else.
The only exception I noticed was the Czech President. Download his talk in the IVR format playable by RealPlayer 11. In the 6.99 MB file (9 minutes), Václav Klaus starts to talk in 30 seconds. See also the transcript.
I have watched about 20 speakers and it's just a complete catastrophe. If someone suggested that Czechia is going to leave the United Nations, I would almost definitely agree. It's an organization full of bureaucrats who look like concerned careerist members of Komsomol. All of them are ready to say an arbitrary amount of lies, none of them is willing to think with his or her brain, and their statements reflect neither science nor the opinions of the people of the Earth.
While the percentage of skeptics among scientists as well as the population is of order 10-50 percent, there is exactly one leader of a U.N. member country that has the courage to offer his skeptical viewpoint. I think that this proves that most politicans in the current world are spineless jerks.
It seems that Klaus is a brave man. After having heard dozens of these puppets saying that no one is allowed to disagree and everyone has to consider stupid girls from Greenpeace to be the main constituency of the international organization - and literally tons of similar ideological and alarmist garbage - it is non-trivial that he gave the talk that he has prepared.
The Cuban minister who speaks now is very characteristic, too. Climate change is caused by consumerist capitalist countries and Fidel Castro has discovered this fact. What he says is otherwise identical - this Cuban viewpoint is the pure essence of the global warming movement. I think that the Cuban minister's comment is fair: it really seems that nearly the whole world has bought the ideology of Fidel Castro. That unfortunately includes even China.
