This stems from a profound misunderstanding of global warming, due to the average intelligence of most involved (see: Al Gore, various celebrities). Global warming is a natural process that occurs because of change in atmospheric composition (the atmospheric composition changes constantly, but, I'm talking about large-scale percentage changes). The nature of energy is to change, and thinking that the atmosphere or anything for that matter will stay the same forever is incredibly dense. If we want to restore the previous conditions, simply not producing as much CO2 is not going to work. That's not how chemical interactions work. It's a system, and to get the outcome that you want, you have to change the contents of the system. Reducing the amount of one chemical will not change the effect. You would have to release different gases into the atmosphere in a controlled way. It would happen again anyways. It's the natural process. If you have predominant O2 users, CO2 is going to increase. Also, calling it a religion is an offense to the word, and does not satisfy the definition anyways. It has no text which it holds as inspired. It has nothing that it worships. It has no rites (rites are much different than actions; rites are symbolic actions which you put faith in). It makes no predictions as to long-term human inhabitation, and it has little to nothing to say about the past that isn't given to science. It cannot claim that facts are what it worships, because it's being selective in its facts... And while some of you (I wanted to, but eh) might say, "Hey, that's a religion", there's still a difference. Religions select their facts based on what they want to be true based on their sacred texts; the green movement selects their facts based on what they think they understand about the concept of global warming. This makes them a group of people following a philosophy, not a religion, and they should be treated as such. They are proponents of a system, not worshipers. The system is based on protecting the environment, and thus, environmentalism, making them, environmentalists.
