I'll start with the assumption that we are all agreed, Anthropogenic Global Warming is a fact. Humans are wrecking the place, and we have to change things to fix it. Calgary is a big player in this global game because we are the oil and gas capital of Canada, and Canada is a major player in this game because of the oil and gas and oil sands in Alberta. Calgary is a very car-oriented city; there have been any number of times I have wanted to walk somewhere and simply couldn't because of how the roads were constructed with no option for pedestrians.
The City of Calgary is making noises about how we should all get out of our cars and use public transportation, then they jack public transportation fees sky-high, start charging for using park-and-ride lots, and don't even have service to large parts of the city in off hours. They go out of their way (literally, with new construction projects) designed to keep people in their cars longer by eliminating road after road as a commuting access.
I am having a really hard time figuring out what their end game is; you want us in our cars longer, but you want us out of our cars, but you want us to have to take cars, but you want us to pay more for public transport; my head hurts just trying to wrap my brain around any possible logic they might be using. I weep for the future of humanity.
