flag Thawing Arctic ice and permafrost are speeding up microbes, releasing greenhouse gases and mercury, worsening climate change.

flag Thawing polar ice and permafrost are accelerating microbial activity in Arctic and alpine regions, releasing greenhouse gases and contaminants like mercury, according to a McGill University review. flag Rising temperatures boost microbial metabolism, speeding carbon cycling and worsening climate change, with extreme weather events increasing across the Arctic over the past 30 years. flag These shifts disrupt ecosystems, threaten species like reindeer, and contribute to Arctic browning and carbon imbalance. flag Despite their global importance, polar regions face research gaps due to limited data, funding, and accessibility. flag Scientists urge expanded monitoring and international cooperation to improve climate projections.
