Antarctica & Arctic

"Soaring temperatures are rapidly thawing permafrost, leading to huge sinkholes called thermokarst. Northern fires are making the situation even worse."

"Forces profound and alarming are reshaping the upper reaches of the North Pacific and Arctic oceans, breaking the food chain that supports billions of creatures and one of the world’s most important fisheries."

"The immense and forbidding Southern Ocean is famous for howling gales and devilish swells that have tested mariners for centuries. But its true strength lies beneath the waves." "Wilder winds are altering currents. The sea is releasing carbon dioxide. Ice is melting from below."

"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."

"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."
