New research shows that climate change threatens the carbon sink function of the Arctic.

A new international study shows that climate change may be weakening the ability of the Arctic fjords to effectively sequester carbon. The research has been published in the latest issue of the journal "Communication Earth & Environment," providing important insights into the impact of climate change on polar ecosystems. Arctic fjords are complex marine ecosystems that have long been important carbon sink reservoirs, crucial for regulating atmospheric carbon dioxide and global climate. However, with the rapidly changing Arctic environment due to rising temperatures, the stability and efficiency of this natural carbon buffering mechanism are facing increasing risks.
