• Arctic’s Shifting Role: A new study reveals that a third of the Arctic’s vast permafrost region, previously a carbon sink, is now a source of greenhouse gas emissions.
• Permafrost Thaw: Melting permafrost due to climate change is releasing methane and carbon dioxide stored for millennia.
• Increased Emissions: This shift from sink to source accelerates global warming, creating a vicious cycle.
• Previously Absorbed Carbon: The released emissions are a significant amount, equivalent to the annual carbon footprint of the entire European Union.
• Widespread Impact: The study focused on Siberia, but the trend likely applies to other permafrost regions.
• Urgent Action Needed: The findings highlight the urgency of curbing climate change to prevent further permafrost thaw and emissions.
