Actually although CFC is a greenhouse gas, in this article I described it in the context of destruction of the ozone layer, a different problem. Only one paragraph deals with global warming (which is very adequately dealt with elsewhere), and it doesn't support or deny it exists, just states what could happen. What was the reason for the "held to be damaging" change? It is pretty securely known that CFCs are damaging, hence the massive banning of them. -- sodium |
