Wayne Davidson operates a weather station in a community that is as far north as can be reached in Canada. The Star Phoenix newspaper of Saskatoon, Saskatche- wan, reports this longtime weather observer says the “dark” is looking different in this portion of the Arctic. In Resolute Bay, Davidson reports the perpetual darkness that surrounds the Arctic for three months is getting brighter. He contends global warming is creating more light, thus reducing the amount of darkness. Living in Resolute Bay for 25 years, his observations note the warm layer of air over the Arctic channels light from the south. He says the refraction of light at the intersection of warm and cold air discharges light and temperature differences increases the light’s distance and its brightness.
