Arctic Ocean November 2019
On November 16, 2019, there was little sea ice between Greenland and Svalbard. For reference, the image below has been added, showing coastlines for the same area.
The image on the right shows that the average air temperature (2 m) on November 15, 2019, was 4°C higher over the Arctic than 1979-2000.
Ocean heat is rising up from the Arctic Ocean, while a wavy jet stream enables cold air to leave the Arctic and descend over North America and Eurasia. On November 13, 2019, it was warmer in Alaska than in Alabama.
The image below shows temperatures north of 80°N. The red line on the image shows the 2019 daily mean temperature up to November 16, 2019. The temperature is now well above the 1958-2002 mean (green line). The image also shows the freezing point of fresh water (273.15K, 0°C or 32°F, blue line).
The freezing point for salt water is lower, at around -2°C, or 28.4°F, or 271.2°K. In other words, a rise in the salt content of the water alone can make ice melt, i.e. even when the temperature of the water doesn’t rise.
The image below shows that Arctic sea ice volume has been at record low levels for the time of year for some time.
As the image below shows, Arctic sea ice extent in the Chukchi Sea is currently very low.

The situation is dire and calls for comprehensive and effective action, as described in the Climate Plan.
• Climate Plan
• It’s warmer in Alaska than in Alabama today
• 100 weather observing stations across the U.S. are forecast to tie or break their record low temperatures
• 2020 El Nino could start 18°C temperature rise
• Critical Tipping Point Crossed In July 2019
• Most Important Message Ever
• When will we die?
• Arctic Ocean overheating
• How extreme will it get?
• Warning Signs
