"A thawing of permafrost in beaver-built wetlands can release vast stores of greenhouse gases to warm the climate, but Native peoples are already feeling the rodent’s impacts." "When the beavers came to streams near the Alaskan village of Venetie, the fish disappeared."
"Scientists discovered a mammoth nesting ground with an estimated 60 million icefish nests in the Weddell Sea."
"The high Arctic saw a dramatic rise in lightning in 2021 in what could be one of the most spectacular manifestations of the climate crisis."
"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."
