Shouldn't we capitalize Global Warming just as we do other world religions?

Recently, several news organizations reported that former Vice President Al Gore has called for the reclification of Global Warming from science to religion (an ideology based in faith and not in fact). While I applaud this move, it does start me to thinking. Why are some people not capitalizing the words Global Warming? I saw in the news today the words written in lower case!!! I just think that Global Warming should be given the same respect as all other major world religions. What do you think?
