Posibles causas y atención al comentario si ésto se hace periódico:

"It is proven that during Ice Ages dust level in atmosphere is very high. The higher dust content the colder.

This event was exceptional, but if for some reasons this becomes periodical it can have serious impact on climate, I dare to say it can trigger descent to Ice Age.

All this is caused by position of Jet Streams and those are defined by position of Hadley, Ferrel and Polar cells."
