Average Arctic sea ice extent for November was the lowest on the satellite record, reflecting unusually high air temperatures, winds from the south, and a warm ocean. Antarctic sea ice extent quickly declined in November, also setting a record low for the month – in marked contrast to recent years. For the globe as a whole, sea ice cover was exceptionally low, according to the U.S. National Snow and Ice Data Center (NSIDC).
In November 2016, Arctic sea ice extent averaged 9.08 million square kilometers (3.51 million square miles). This is 800,000 square kilometers (309,000 square miles) below the previous record low in November 2006 – about the size of France and the United Kingdom combined.
At this time of year, air temperatures near the surface of the Arctic Ocean are generally well below freezing, but this year has seen exceptional warmth. For a brief period in the middle of November, total extent actually decreased by 50,000 square kilometres – an almost unprecedented occurrence for November over the period of satellite observations, according to NSIDC.
Continuing the warm Arctic pattern seen in October, November air temperatures were far above average over the Arctic Ocean and Canada. Air temperatures were locally up to 10 degrees Celsius (18 degrees Fahrenheit) above average near the North Pole, according to NSIDC. Europe’s Copernicus Climate Change Service also reported exceptionally warm temperatures in the Arctic.
This year, Antarctic sea ice reached its annual maximum extent on August 31, much earlier than average, and has since been declining at a fairly rapid pace. This Antarctic sea ice extent in November: NSIDC led to a new record low for the month of November over the period of satellite observations. Average extent in November was 14.54 million square kilometers (5.61 million square miles). This was 1.0 million square kilometers (386,000 square miles) below the previous record low of 15.54 million square kilometers (6.00 million square miles) set in 1986.
Part of the explanation for this appears to lie in changing wind patterns, with large large scale winds blowing north to south, tending to compact and compress sea ice, according to NSIDC.
“The processes governing the evolution of sea ice in both hemispheres is a result of different atmospheric and oceanic processes and geographies and it unlikely that record low conditions in the two hemispheres are connected,” said the NSIDC.

Thirty kilometres from the bustle of downtown Abu Dhabi, lies a remarkable undertaking that could one day change the environmental impact of air travel.
While energy use is commonly associated with lighting or transportation, more than half of the world’s energy consumption serves a simple function: heating things. This ranges from heating homes and buildings, to firing up industrial production, or even cooking. And because heat is mostly produced by burning fossil fuels, heat production accounts for almost half of the world’s carbon dioxide emissions.
Today, the potential for lower SWH costs lies mainly in equipment and manufacturing. These can be improved by economies of scale – for example from their use in district heating – simpler designs, development of more manufacturing capacity and use of better techniques, including automation. While the initial cost is higher than gas or electric boilers, operating costs for SWH are much lower, even when electricity is used as a backup.




The Work Programme for the provision of technical assistance to Western Balkan 6 Contracting Parties for supporting the creation of a regional electricity market was published today. It is aimed at removing the existing legislative and regulatory barriers and enhancing the institutional structures necessary for the functioning of the market in line with the Energy Community Treaty. The project “Technical Assistance to Connectivity in the Western Balkans – Component 2: Regional Energy Market” is funded by the European Union and implemented by the Energy Community Secretariat.






An International Atomic Energy Agency (IAEA) team of safety experts said Italy is committed to effective nuclear regulatory oversight but faces challenges related to resources and needs to further develop policies for nuclear safety, decommissioning and managing radioactive waste.


The European Commission has launched a new database on the EU’s building stock to monitor the energy performance of buildings across Europe. The database – called the EU Building Stock Observatory – provides information on buildings’ characteristics including their construction period, energy use, onsite renewable energy and renovation rates.




The European Investment Bank (EIB) has signed a EUR 190 million loan agreement with Lietuvos Energija for the greenfield construction of new combined-heat-and-power (CHP) plant in Vilnius. The project is expected to lower municipal waste landfilling, decrease energy prices as well as cut emissions and improve the security of energy supply in the country. The EIB loan is guaranteed under the “Investment plan for Europe” of the Juncker Commission.
