Narrative:

I was recently dispatched from [a west coast airport] on a northern random route to paris. The B767 was fueled with jet a; which has a minimum temperature limit of -37 degrees C. The coldest enroute fuel temperature from the flight plan remarks the dispatcher gave us was -38 degrees C; lower than our limit. This essentially required us to ignore the speeds and altitudes we were forecast to fly in order to keep our fuel temperature above the limit. The sat at 64N on our route of flight actually reached -70 degrees C; pretty darn cold. If [we are] going to fly these northern latitudes in this aircraft; it needs to provide the aircrews with some minimum polar training; equip the aircraft with a polar suit in the event of a diversion (how will the first officer do a walk around in minus 26 degrees; which was the temperature at one of our diversion alternates; cyyq?); and provide aircrews with the minimum fuel freeze point for the fuel loaded. The operation as currently conducted is not entirely safe.
