"Public health officials have told residents of Canada’s northernmost capital not to use tap water for drinking and cooking because of suspected fuel contamination in the city’s water supply."
Antarctica & Arctic
"Russian Arctic oil is moving north into territories previously untouched by man. The latests lands up for industrial expansion might be the shorelines and delta areas of several Arctic rivers and bays."
"Sea ice is more extensive than in recent low years, but still far lower than historically — even as other markers, such as thickness and age show declines."
"The hole in the ozone layer that develops annually is “rather larger than usual” and is currently bigger than Antartica, say the scientists responsible for monitoring it."
"With climate change threatening the sea ice habitat of Emperor penguins, the U.S. Fish and Wildlife Service on Tuesday announced a proposal to list the species as threatened under the Endangered Species Act."
"A hydrophone reveals a vital Antarctic feeding and breeding ground for the world’s second-largest whale."
"Arctic sea ice fell to its lowest extent on record for this time of year on July 5, even though the spring had so far been relatively cool and stormy — conditions that, in the past, would have protected the ice."
"Part of the Arctic is nicknamed the “Last Ice Area,” because floating sea ice there is usually so thick that it’s likely to withstand global warming for decades. So, scientists were shocked last summer when there was suddenly enough open water for a ship to pass through."
"Warming of the surface of the Arctic is matched by a colder polar vortex high in the atmosphere, which is speeding the breakdown of the Earth’s shield against ultraviolet rays."
"The Arctic is now warming three times as fast as the global average, and faces an ongoing barrage of dangerous climate and environmental pollutants, Arctic Council experts warned at the start of their meetings in Reykjavik, Iceland this week. Black carbon, or soot, remains high on the list of concerns because of its negative effect on human health and because it accelerates the Arctic meltdown by darkening snow."
