"The changes happening at the top of the planet could unfold elsewhere in the years to come, scientists report." "Across the icy dome that crowns the Earth, rising temperatures are turning the tundra greener and more lush. Beavers are expanding their range. Garbage from passing ships is fouling the shores. Wildfires are scorching the once permanently frozen lands of Siberia."
Antarctica & Arctic
"Scientists have discovered a series of worrying weaknesses in the ice shelf holding back one of Antarctica’s most dangerous glaciers, suggesting that this important buttress against sea level rise could shatter within the next three to five years."
"Climate change is bringing potentially deadly dinoflagellate blooms to the Far North, posing a new risk to food security."
"The planet’s warming is transforming the sprawling and fragile Arctic, moving it toward a future that can be summed up in four words: more rain, less snow. But now researchers say that unprecedented shift — and the profound impacts that are likely to accompany it — could come decades sooner than previously thought."
"The saltier Atlantic broke through layers of ice and freshwater, contributing to the Arctic’s warming."
"A smelting company has poisoned rivers, killed off boreal forest and belched out more sulfur dioxide than active volcanoes. Now it wants to produce more metal for the “green economy.”"
"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."
"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."
