Iceland is warming faster than most countries, two to four times faster than the global average temperature rise. A quirk of geography means that the island's plants and animals are having to cope with rapidly rising temperatures whilst their neighbours in the rest of northern Europe warm much more gradually. Glaciers are melting, trees are growing much faster and arable farming is suddenly possible and profitable.

Tom Heap travels through Iceland to gauge the impact on the landscape and the people. Can the rest of the world learn lessons from Iceland's experience?
