Ian, that is fucking stupid. You know damned well what that curve means. It does not mean that where the curve hits the zero mark there is going to be an ice free Arctic Ocean. What it does mean, within the plus and minus of the dots on the graph, by the data, that is the most likely time for that to happen. And there is absolutely nothing in that graph that indicates cyclic activity. In fact, there is a definate downward trend.,
You are an ass. I gave you an IPCC graph showing lower ice extents in the 70's before full time satellite coverage. Strong evidence of cyclical behaviour. At the very least proof that there is not a steady downward trend in IE.
Next, I said 20 years for ice free conditions instead of the three years for November and five years for December, as indicated on the SkS graph. Like I said, anyone who believes the Arctic Ocean will be ice free in winter is a fucking idiot. Obviously that includes you.
