The Comoros Islands in the Indian Ocean, between Mozambique and Madagascar, are a small nation of sparkling blue lagoons and picture-postcard beaches. But the country is politically unstable and a report published today says it is the world's most vulnerable country to the future impacts of global warming such as increased storms, rising sea levels and agricultural failure.

At the other end of the scale, Canada is the best place to move to if you want to be a climate change survivor in the decades ahead (although Britain is also a good place to be as a warming atmosphere takes hold).

The best-to-worst rankings are revealed in the first-ever climate change vulnerability index, produced by Maplecroft, a British consultancy which specialises in the mapping of risk. Its study, The Climate Change Risk Report, looks in great detail at global warming risks in 168 countries.
