Frequent Arctic wildfires could cut snow cover by 18 days, impacting global climate and ecology
The correlation between Arctic wildfires and abnormal snow cover under global warming is of growing concern. A comprehensive quantitative assessment by researchers at The Hong Kong Polytechnic University (PolyU) has shown that increasingly frequent seasonal wildland fires across the Arctic in recent years have delayed snow cover formation by at least five days and could lead to a future 18-day reduction of snow cover duration, with implications for global ecosystems.

Antarctica’s collapse may already be unstoppable, scientists warn
Researchers warn Antarctica is undergoing abrupt changes that could trigger global consequences. Melting ice, collapsing ice shelves, and disrupted ocean circulation threaten sea levels, ecosystems, and climate stability. Wildlife such as penguins and krill face growing extinction risks. Scientists stress that only rapid emission reductions can avert irreversible damage.
