Sea Surface temperatures have jumped remarkably in 2016. The graph shows the Arctic(67N+), High Arctic(80N+) and Global sea surface temperatures, from the NOAA-ESRL time series, converted to standard deviations based on the 1948-2016 average for each series. To avoid the impact of the past two years the trend line shown only covers the period to 2014. Each of the series has jumped nearly one std dev this year to around three above average.
