I don't think they are the same thing.Here is what I've always wondered; perhaps there are scientists outside who can help me out. In New York City, 99% of trains have functioning air conditioning believe it or not; even on the old IRT whose trains are very very narrow and for which we were told for years it couldn't be done (which always leads me to be suspicious of those who say the London tube cannot be air conditioned; whether given the climate it is worthwhile is another question altogether). The question is in grade school we studied something called the conservation of energy. To put it bluntly, the heat has to go somewhere. I wonder if the stations and tunnels are much hotter now, in NY, with the air conditioning (of course the stations should be a/c'd next but doubt that is on the drawing board). Same thing goes for outside temperatures. I wonder if all the airconditioning present in 99% of the cars we drive in America (at least in the NY area) contribute to global warming. |
