· Changes in arctic conditions (arctic ice cap may disappear, permafrost will melt during the summer)
· As the ice melts, sea levels will rise and flood low lying areas of land.
· Expansion of temperate species increasing competition with native species (e.g. red fox vs arctic fox)
· Increased spread of pest species and pathogens/diseases
· Behavioral changes in native species (e.g. hibernation patterns of polar bears, migration of birds and fish, seasonal blooms of oceanic algae)
· Loss of habitat (e.g. Marine species in the arctic water may become extinct as these are very sensitive to temperature changes within the sea)
· Extinction and resultant loss of biodiversity as food chains are disrupted
