"Bangladesh and India are the countries most vulnerable to climate change, according to an index on Wednesday that rates the Nordic region least at risk.
British consultancy Maplecroft said its rankings showed that several "big economies of the future" in Asia were among those facing the biggest risks from global warming in the next 30 years as were large parts of Africa.
It said poverty and large low-lying coastal regions prone to floods and cyclones were among factors making Bangladesh the most exposed country. India, in second place, was vulnerable because of pressures from a rising population of 1.1 billion.
Madagascar was in third place, followed by Nepal, Mozambique, the Philippines, Haiti, Afghanistan, Zimbabwe and Myanmar. Vietnam, in 13th place and flood-hit Pakistan in 16th were also in the most exposed group."
