Climate change in the Artic

Effects

Negative

Positive

Causes

Increase in greenhouse gases prevents sunlight from escaping back to space this addsto the Abedo effect

Modernisation - Increase in manufacturing sector that is powered by fossil fuels

Importance

Allows the thermohaline circulation to occur as the ocean water cools in North Atlantic which becomes denser and sinks to the ocean floor that helps to form an ocean circulation. This helps to distribute heat between the Earth's coldest and hottest part making the Earth habitable

The white ice sheet in the Artic reflects about 85-90% of the sun's heat

The permafrost in the Arctic traps the Earth's CO2 and the melting of ice cap (and permafrost) will cause more release of CO2 warming the Earth - 11% of the world's soil carbon is trapped here

The Artic is habitat for the Artic species, a change in climate, the melting of ice will create difficulties for the species that lives on it and the whole food chain of the Arctic will corrupt (Artic also contains endemic species)

Provides the Inuit's income by providing marine mammals which are declining in numbers - 80% of Inuit still hunts fishes , caribou and marine mammals

Female polar bears rely on spring to build up their body fat to ensure their survival during the summer when the ice recedes naturally and the early melting of ice meant that they have less time to hunt (3 months less) and survival will prove to be difficult
