A row of mangrove trees sticking out of the sand, exposed by low tide off Kutubdia island in the Bay of Bengal, is all that remains of a coastal village that for generations was home to 250 families. The villagers were forced to flee as their land, which had been slowly eroding for decades, was finally engulfed by the ever-rising tide five years ago. For the embattled people, the distant trees serve as a bittersweet reminder of what they have lost. They also act as a warning of what is to come UN scientists predict some of the worst impacts of climate change will occur in south-east Asia, and that more than 25 million people in Bangladesh will be at risk from sea level rise by 2050. It is well known that many of the countries most vulnerable to climate change are among those who contribute to it the least, and here that’s certainly true. The carbon footprint of Kutubdia’s 100,000 islanders is small - most do not even have access to a regular electricity supply. But they fear that for them, time is already running out. So far, members of the fishing community of Ali Akbar Dail, perched precariously on a strip of coast next to the embankment, have learnt to adapt to the many natural disasters thrown at them. When the cyclones hit, they hoist their children on to their shoulders and head for the network of cyclone shelters. These shelters, along with the country’s early warning system, have dramatically reduced fatalities. However, after a year that they say has brought more - and more powerful -storms than before, the fishermen are engaged in a battle for survival against their only asset: the ocean. Scientists say the sinking of islands in the Bay in Bengal is due to natural and possibly man-made climate change. Erosion linked to storm surges, for instance, predate global warming. But sea surface temperatures, linked to sea level rise, have risen in the Bay of Bengal. In a report published last month, scientists said they believed the higher surface temperatures in the Indian Ocean were causing cyclones to increase their frequency and intensity. There are too many challenges. People are losing their ancestral land, and they are having to migrate to other places. There, they have to adapt to a new environment. But in their new home, they are still anxious and uncertain about the future.
