How Not to Analyze Tide Gauge Data

There’s another paper about sea level rise in the Journal of Coastal Research by P. J. Watson (2011, Is There Evidence Yet of Acceleration in Mean Sea Level Rise around Mainland Australia?, Journal of Coastal Research, 27, 368–377). According to this powerpoint, Watson is genuinely concerned about sea level rise due to global warming and argues forcefully for addressing the issue. His primary interest seems to be: to help those responsible for protecting Australia’s coastline be as well prepared as possible for the impending sea level rise. That’s a noble motive, and I wish him success. But in spite of the best of intentions, I can’t put much stock in Watson’s published results because it’s clear that he is no data analyst.
