Scrambling for the Arctic

An international summit has begun in Moscow, the Russian capital, to consider rival claims to mineral rights in the Arctic.

It is thought a quarter of the world's undiscovered oil and gas resources lie beneath the arctic ocean, and now global warming is making it more accessible.

Under the UN Convention on the Law of the Sea, coastal nations can claim exclusive rights to natural resources on or beneath the sea floor up to 370 kilometres beyond their land territory.
