Is global warming chiefly caused by humans or by natural phenomenon?

Some claim that humans are the chief cause of the warming that has occurred over roughly the past century, while others claim that our role has been relatively insignificant as compared to natural forces. What is your opinion?

    I suppose this is the normal way of developping: beginning to end.

    Because we’re short sighted, look for instant gratification, and don’t think of think of the future. Big business and governments want to make money NOW and have the attitude of “I don’t care. I won’t be in office that far down the road” or “I don’t care, I won’t be alive when the environment is that bad it can no longer sustain human life.”

    some of the global warming since 1850 could be a recovery from the Little Ice Age rather than as a direct result of human activities.
