- Case Study: The Arctic
- Environmental
- 2004-2005 there was a 14% loss of Arctic Ice
- 40% Permafrost thaw predicted
- Will release methane which will harm atmosphere
- Can lead to increase in new species (eg. The Spruce Bark Beetle)
- Increase in freshwater can disturb Arctic conveyor belt which can lead to massive impacts in Europe
- Ecological
- Change in river patterns can cause the fish to suffer (eg. Arctic Char and Lake Trout)
- The warmer river means that marine plants will decrease, meaning smaller fish have less to feed on. This can impact animals higher up the chain (eg. Polar Bears and Seals)
- Melting of ice decreases hunting season for polar bears. They can't hunt on the ice for seals so they can't feed their babies. This could eventually lead to extinction.
- Biome shift as Tundra moves further North and coniferous forest takes its place
- Could lead to invasion of alien species
- Social
- Enhanced marine fisheries due to introduction of cod.
- Melting ice means it will be more accessible for marine shipping, however land-based transport will be disrupted due to thawing permafrost
- Polar bears may begin to raid houses
- May lead to decline of food security
- Environmental
