A) Thawing of arctic permafrost & increased decomposition of dead organisms, releasing more CO2 and CH4 into the atmosphere, compounding the effects of global warming.
B) Thawing of arctic ice caps which may warm the Arctic Sea, changing world currents and climates.
C) Loss of arctic and glacial ice would increase worldwide sea levels.
D) Organisms such as seals, walruses and polar bears would need to travel farther to find food (normally found under arctic ice). They would also have fewer places to rest so might be in danger of drowning as well as starvation.
E) Disruption to entire food chains as some species decline or disappear.
F) Increased sea and land temperatures increases the chance alien species and diseases may move into arctic regions.
