You ignored my point entirely.<p>I agree with you that the current sea level is about where it was 23 years ago. I don&#x27;t agree with you that the graph you linked isn&#x27;t trending upwards. Obviously if you have a sinusoid that slowly trends up (where the yearly delta is &lt;&lt; the (max-min) periodic variation), it&#x27;s going to oscillate in such a way that a point-in-time view of it might see lower values than the average. That&#x27;s what sinusoids do.<p>(If it&#x27;s not obvious to you that the trend, rather than the current value, is the interesting data, then this whole discussion is a waste of time.)<p>So now that we&#x27;ve gotten that out of the way:<p>I&#x27;m arguing that you&#x27;re doing a really bad job of convincing anyone because of your hostility to rational questions and discussion on the subject. I&#x27;m doing this a) to inform you, in case it wasn&#x27;t obvious to you (and it seems like it wasn&#x27;t) and b) because it&#x27;s fun to point these things out; Hacker News seems to often enjoy meta-discussions about arguments.
