A trust fund set up to help a South Pacific nation gravely threatened by climate change has invested in coal mining, gas exploration and the world¡¯s largest crude oil refinery, an investigation has revealed.

Low-lying Pacific island nation Tuvalu said it was reviewing the ¡°fossil fuel exposure¡± of the $200 million fund after it was presented with the findings.

Few countries are more exposed to climate change than Tuvalu, a chain of coral atolls reckoning with acidifying oceans, tropical disease and rising seas.
