The high temperature anomaly that occurred in February 2016 was partly caused by El Niño. Nonetheless, there is a threat that the February 2016 anomaly was not a peak, but instead was part of a trend that points at what is yet to come to come.
As the image below shows, 93.4% of global warming goes into oceans. Accordingly, ocean heat has been rising rapidly and, as the image below shows, a trend points at a huge rise over the coming decade.
Ocean temperature rise affects the climate in multiple ways. A recent study confirmed earlier fears that future increases in ocean temperature will result in reduced storage of carbon dioxide by oceans.

Arctic sea ice is rapidly thickness rapidly. The image on the right shows that the thicker sea ice is now almost gone (image shows sea ice on August 6, 2016, nowcast). The image below gives a comparison of the years 2012, 2013, 2014 and 2015 for August 6.
The image below, by Jim Pettit, shows Arctic sea ice volume.

There's a danger that, as the temperature of the Arctic Ocean keeps rising, huge amounts of methane will enter the atmosphere due to destabilization of hydrates at its seafloor.
