People in the High Arctic say their 24-hour darkness isn't as dark as it used to be, and a weather researcher says it's because of the warming climate.
"We still have a daylight and there's still blue, green, red down there — there's sun sign still," said Zipporah Ootooq Aronsen, who lives in Resolute Bay, Nunavut. "It's not usually like that."
People in Resolute Bay now sometimes see a distant island that in the past was only visible during daylight hours.
"It never happened like that before," Aronsen said. "Now we can see it once in a while, when it's a clear day."
Wayne Davidson, a weather researcher in Resolute Bay, said warmer thermal layers over cold dense polar air cause light to bend and travel farther.
