Sure - I don't think that changes my point though. And I have some sympathy for the argument that there may be some changes we shouldn't rush into without understanding them better (e.g. Sri Lanka's experiment with organic farming), or until we have better/cheaper technology available - what we should be doing now is a lot more research into mitigation and adaptation options.
