A year ago I wrote an article at WUWT analyzing the recent upward trend in summer Arctic sea ice extent. Despite challenges of statistical irrelevancy, the trend has continued another year. Arctic ice experts, that have repeatedly predicted the demise of summer ice, don’t have an explanation for a 10-year trend that contradicts their predictions, beyond statistical variability or unexplained natural variability. They believe the upward trend will end any year, and there were high expectations that 2017 was going to be that year, due to the low maximum in March. As we will see a low maximum has no predictive value.
