Climate change creates arctic lights ?

[qoute]Eskimos and scientists report a strange "lightness at noon" that is turning the usual all-day darkness of the high Canadian Arctic into twilight, apparently in defiance of natural laws. Canadian government officials say it may be the result of an unusual atmospheric phenomenon caused by global warming.
Inuit hunters are telling the government's weather station at Resolute Bay - Canada's second most northerly village, 1,000 miles from the North Pole - of a new light in the sky.
And Wayne Davidson, the Canadian government official who runs the station, says he believes it it caused by climate change.[/qoute]

Things are going strange lately, this news makes my guts tickling. Is climate change behind this lights? Any explanation why? Has to do with ozone hole

Please help...
Thank you,

But Mr Davidson's investigations, backed by other scientists, suggest a more prosaic explanation. Warmer air, from global warming, is overlaying the cold air of the Arctic and the interface between the two creates a kind of "mirror in the sky" which reflects the sun's rays from further south.

Same mechanism as which causes mirages.

In right conditions mirages can be seen hundreds kilometers away from real "object" and mirage is just light which has been refracted by temperature/density differences in atmosphere.

thanks, E_T I'm gratefull for your explanation
