Concept: Arctic
Freshwater and carbon export to northern Alaska estuaries increased
Climate-driven freshwater and carbon surges into Alaska's Arctic coastal waters

Methane increases were linked mainly to wetlands in Africa and Asia
Atmospheric methane surge linked to declining chemical breakdown and changing wetland emissions

Global glacial lakes store more water but vary widely in longevity
Global inventory of glacial lake volumes and how they are changing with deglaciation

Bias-corrected Greenland accumulation maps align more closely with observations
Correcting snow accumulation estimates from climate models using field observations

Organic enrichment reshaped Arctic deep-sea nematode communities
How Arctic deep-sea worms respond to changes in food supply

Arctic bioclimatic extremes have increased in many areas
Extreme weather events are becoming more frequent across the Arctic
