I don%u2019t know whether the report is full or just some of the statements were taken out of context, otherwise its sounds ridiculous for a person of his position to make such a contradictory statement. To bring down carbon emission (which is the cause of green house effect) alternate source of fuel is needed, which means a source of fuel which does not add up to the carbon emission. To my understanding, water, wind, nuclear etc are sources which have no carbon emission. So it would be better if the director of ICTP think all angles before making a statement. Whether we need US or any other help for that matter is debatable. Please don%u2019t confuse readers and if there is more to this report, publish all of it. Don%u2019t publish just to have a good headline.
