I understand that you are correcting some assertions, but the way you did questioned the scientific competence of other contributors is reducing the value of the entire sentence you were replying to. You are throwing out the baby with the bath water. The key message I wanted to stress, with additional contributions to the discussion, is that we have to be concerned. If you agree with me on this I'm fine. Unfortunately however your corrections suffered the same problem of the ones you were correcting. In particular I do not agree with you on these two sentences: "Climate change is not predicted to exterminate humans." It is. It's not predicted to make Homo sapiens sapiens extinct, like you probably meant, but many humans can be exterminated by repentine climate changes (think to famine, wars, drought). "This melting cycle was happening before the industrial revolution and was not created by humans." Human-made contributions are perturbing the cyclicity, to an extent that can lead to a non-cyclical patterns.
