Arctic warming negatively affects the foraging and breeding ecology of native Arctic mammals, such as Arctic foxes or Arctic reindeer. [91] In July 2019, 200 Svalbard reindeer were found starved to death apparently due to low precipitation related to climate change. [92] This was only one episode in the long-term decline of the species.
Pollution in the Arctic Ocean is primarily the result of economic activities carried out on land, which is sources from locally, regionally, and globally origins. [1] There is also the inclusion of industrial development in the Arctic region, northern rivers, and the effects of military activities, particularly nuclear activity – as well as the influx of pollutants from other regions of the ...
Climate change causes sea ice to melt, transforming the Arctic from an icy desert into an open ocean. Polar bears and seals may lose their habitats, phytoplankton growth may increase and fuel the Arctic food web, which may lead to higher carbon burial rates and possibly decrease the amount of CO 2 in the atmosphere.

Natural forces cause some variability, but the 20-year average shows the progressive influence of human activity. [2] Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth’s climate system.
Whilst the Arctic region is one of many natural sources of the greenhouse gas methane, there is nowadays also a human component to this due to the effects of climate change. [86] In the Arctic, the main human-influenced sources of methane are thawing permafrost, Arctic sea ice melting, clathrate breakdown and Greenland ice sheet melting.

Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
