To understand the point meme is making one requires the understanding of 'belief systems'.<quoted text>
I do not understand what you are trying to say here. Most religious people follow the example of Rev. Jerry Falwall and contend that Global Warming is a hoax.
Both CAGW and revealed Religions are grounded in the same principle belief. Those who 'believe' do so based on their faith in the experiences (opinions) of others. These opinions are then viewed as Truth and Fact.
The word often associated with such a belief system is "dogma"... A statement or assertion based on unproven or unprovable principles.
Bottom line... the point is CAGW is, by it's very nature, a religion.
