Planes and weather

All planes grounded and we get several straight days of lovely sunny weather. Any connection between high-altitude aviation-related waste products and vapour trails on the one hand, and cold nights/hot days? Does "clear the skies" = clear skies?

    What's your theory?

    Probably just a coincidence. In theory, the water vapour from combustion warms the Earth, the particulates reflect sunlight, and so cool it. In practice, these are dwarfed by cars and power stations.
