I was watching the weather forecast and the smoke from the forest fires in Canada has risen in the atmosphere and had been carried by the jet stream up across the Atlantic and towards the UK. The smoke particles are not low enough to cause breathing problems, but they are in the right place to scatter the light more at sunrise and sunset. This should result in brighter red and orange skies in the morning and evenings.

A similar phenomenon happened when Krakatoa erupted in the 19th Century. Then the volcanic dust that was swept into the sky caused changes in the evening light and blue moons being reported. We have to realise how interconnected the world is.
