Above image shows temperatures north of 80°N. The red line on the image shows the 2019 daily mean temperature up to Oct 13, 2019. The temperature is now well above the 1958-2002 mean (green line). The image also shows the freezing point of water (273.15K, 0°C or 32°F, blue line).

As above combination image shows, air temperatures are high over parts of the Arctic Ocean where there is no sea ice. This is where heat gets transferred from the Arctic Ocean to the atmosphere. The image in the left panel shows anomalies on October 14, 2019. Anomalies look set to get stronger, as illustrated by the forecast for October 24, 2019, in the right panel.
The image on the right shows sea surface temperature anomalies. On October 13, 2019, the sea surface near Svalbard was 14.7°C or 26.4°F hotter than 1981-2011.
Arctic sea ice extent is very low. As the image below shows, Arctic sea ice extent was 4.88 million km² on October 13, 2019, the lowest on record for the time of year.

The image below shows that Arctic sea ice volume is also at record low for the time of year.
This lack of sea ice results from rising temperatures of water in the Arctic Ocean. The image below, created with NOAA 2007-2019 June-August sea surface temperature data, shows heating of the sea surface on the Northern Hemisphere, with an ominous trend added.

The situation is dire and calls for comprehensive and effective action, as described in the Climate Plan.
