If the warming exceeds - or thereabouts, there is a significant risk of the entire ice sheet being lost over an estimated 10,000 years, adding up to global sea levels. Warming in the Arctic may affect the stability of the jet stream, and thus the extreme weather events in midlatitude regions, but there is only "low confidence" in that hypothesis.
The 2007 IPCC Fourth Assessment Report concluded that over the last three decades human-induced warming had likely had an influence on many biological systems. [25] [26] [27] The Sixth Assessment Report found that half of all species with long-term data had shifted their ranges poleward (or upward for mountain species).
Climate change is modifying fish distributions [6] and the productivity of marine and freshwater species. Climate change is expected to lead to significant changes in the availability and trade of fish products. [7] The geopolitical and economic consequences will be significant, especially for the countries most dependent on the sector.
An increase in temperature due to worldwide climate change has been observed to be greater in the Arctic than the "global average," with Arctic air temperatures warming twice as quickly. [56] [57] The observation of the proportionally greater temperature increase in the Arctic has been termed "Arctic amplification". [58]
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms.
However, research has shown that the North Pacific Ocean, the Greenland Sea and the Barents Sea host the species that are most vulnerable to global warming. [109] The North Pacific has already been identified as a hotspot for human threats for marine mammals [115] and is now also a hotspot for vulnerability to global warming. Marine mammals in ...

The polar seas contain a huge biome with many organisms. Among the species that inhabit various polar seas and surrounding land areas are polar bear, reindeer (caribou), muskox, wolverine, ermine, lemming, Arctic hare, Arctic ground squirrel, whale, harp seal, and walrus. [1] These species have unique adaptations to the extreme conditions.
