Moral responsibility lay with "absolutely everybody - not only in terms of examining our own lifestyle, but in sending a message to governments that it is recognised as a priority by the public," he said. He described as "profoundly immoral" a policy and lifestyle that did not consider future generations.
He said that the question was to some extent about who was prepared to take responsibility, but it was also about the "changes we can make, and which each organisation can make, too". He noted: "That's something the Church of England is having to look at quite seriously in just those terms: we can't talk about it in the abstract, as if we occupied the high moral ground."
Dr Williams was explicitly critical of the United States, and implicitly critical of President Bush. "I don't think it's compatible with the Christian ethic to ignore the environmental degradation that we face - it's a medium-term question for everyone, and therefore a moral imperative," he said. "Nearly a quarter of carbon emissions on the face of the globe are attributable to the United States, and the leadership in the US has been very slow to catch up with us.
When asked how God would judge those leaders who had not moved quickly enough to prevent the millions, and perhaps billions, of deaths that he had forecast earlier in the interview, Dr Williams reflected: "I think if we look at the language of the Bible on this, we very often come across situations where people are judged for not responding to warnings.
"It's very deeply built in. There are choices we can make, each one of us, to change things now, and I think what the Bible and the Christian tradition suggests is that those who have that challenge put before them - and not only that challenge, but the evidence for it - and don't respond bear a very heavy responsibility before God."
Whether you believe in God or not, I think we can all agree with the Archbishop that those who have the challenge put before them and choose not to respond bear a very heavy responsibility to whatever is ultimately good, true and right. Future generations - if there are future generations - will rise up and curse us for what we are allowing to take place.
