What is the role of biodiversity in climate change?
They also ‘soak up’ carbon dioxide from the air, mitigating climate change. … Results showed that biodiversity has a direct positive impact on carbon stocks and can be considered a key part of mitigation policies such as REDD+.
How does climate change affect biodiversity in the Arctic?
It is expected that climate change could shrink Arctic ecosystems on land, as northward moving changes are pressed against the boundary of the Arctic Ocean: the so called “Arctic squeeze.” As a result, Arctic terrestrial ecosystems may disappear in many places, or only survive in alpine or island refuges.
Why is biodiversity important in the Arctic?
Biodiversity includes the multitude of poorly known species, of which there are many in the Arctic, that collectively provide the foundation for food webs and ecosystems. The interactions between humans and their surroundings are also part of the diversity, vitality and sustainability of life on Earth.

How does climate change affect biodiversity in the ocean?
Climate change due to human activity has a direct impact on marine species. It alters their abundance, diversity and distribution. Their feeding, development and breeding, as well as the relationships between species are affected. Rising temperatures lead to different behaviour patterns according to species.
Why is biodiversity important?
Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat.

LOSS OF SEA ICE AND TUNDRA HABITAT.
What is the most important aspect of its biodiversity Arctic Ocean?
Physical characteristics of the Arctic important for structuring biodiversity include extreme seasonality, short growing seasons with low temperatures, presence of permafrost causing ponding of surface water, and annual to multi-annual sea-ice cover.
