Slowing down the runaway climate change in the Arctic Ocean, which is warming more than four times faster than the rest of the planet, over four winters.

The only solution is to stop depositing water vapor from kerosene combustion in the lower stratosphere, between 9,000 and 13,000 meters altitude, for use in global air transport. This is because water vapor persists in the stratosphere for more than four years.

As soon as possible, we need to fly our superb machines below 8,000 meters altitude in the troposphere where water vapor regains its normal lifespan of about ten days.
