Arctic Tundra’s Carbon Release Crisis

The Arctic tundra, historically a significant carbon sink with over 1.6 trillion metric tons of stored carbon, is now releasing CO2 and CH4 due to accelerated warming, which is four times the global average. Permafrost thawing and increased Arctic wildfires exacerbate the release of greenhouse gases, with 2024 noted as the second warmest year since 1900. Efforts to reverse this trend hinge on reducing global greenhouse gas emissions, but CO2 levels continue to rise, reaching 41.6 billion tons. Organizations like NOAA emphasize the urgency of addressing climate impacts in the Arctic, which hold global implications for environmental stability.
