If Antarctic ice is melting due to global warming I guess we need to cool Antarctica.
In busy parts of the sky aircraft vapour trails merge to form a thin layer of high level cloud. This causes less sunlight to reach the ground and the ground is cooler as a result - all part of the phenomenon known as Global Dimming.
Let's fly a fleet of planes, adapted to maximise the volume and reflectivity of their vapour trails, over the vulnerable Antarctic ice during summer days - a 21st century parasol to cool Antarctica.
