Impacts of Global Warming on the Arctic
- Localised shifting of ecosystems in a poleward direction.Coniferous forest will expand into the tundra zone.
- The tundra, with rare arctic plants, will shrink as rising sea levels drown coastal areas.
- Increased forest fires and insect infestation are expected to ravage coniferous forests and reduce both biomass and biodiversity.
- Marine life will respond to warmer sea temperatures and reduce ice cover. Improved food supplied will mean bigger fish stocks and the appearance of new species.
- Fragile food webs could easily be damaged, leading to the loss of tundra mosses and lichens that provide the main food for animals such as the Caribou.
