science π§ Arctic permafrost carbon mostly sinks, not floats
A new study suggests most carbon from thawing Arctic permafrost does not become greenhouse gas. Researchers at AWI examined the seafloor off a Canadian Arctic island near Herschel Island. Up to 0.02 gigatons enter the sea annually, with potential rises of 70 to 150 per cent by 2100. The majority of this carbon settles into the seabed rather than entering the active ocean cycle. The team will now explore the broader ecological effects as part of the 2027 Arctic Pulse campaign. π§
