The decarbonization of the Arctic

Two of the concerns that represent areas where we might have some leverage in our up-coming negotiations with ‘Trump Country’ are also essential  factors in Canada’s crucial decarbonization program. These are Arctic security and energy security – areas in which we are already behind schedule in targets pertaining to the 2015 Paris agreement.

Climate change is causing greater and more rapid temperature increases in the Arctic.  The reason is simple.  Ice and snow are white and therefore reflect a lot of the incoming sunlight. After an initial warming and melting of the snow and ice, the white surface gets replaced with a darker surface of the open ocean, which absorbs more sunlight, thus leading to additional local warming.  

Parts of the coastline are ice-free for longer periods and the ‘Northwest Passage’ is navigable for several weeks very year. This could enable the shipment of supplies which now must be flown in, lowering the now-horrendous cost of food, but also makes the mineral-rich area more vulnerable.

Compounding all the climate-related problems in the Arctic is the fact that per person carbon emissions are much higher there because of the widespread use of fossil fuels for heating and generation of electricity.

A network of small modular nuclear reactors would solve a lot of problems.
