Thousands of rural families in Bangladesh are being pushed into Dhaka and other crowded cities as their land and houses have been washed away, the New Internationalist reports. But by 2070, Dhaka itself will be one of the most climate-stressed cities on earth, according to the UN. Heat stress, river and coastal floods are likely if climate change continues unabated.

Bangladesh is calling for a new UN refugee convention to recognise climate refugees. In the meantime, Bangladeshis attempting to flee across the border to India face a fence-building programme along the border and gun-toting border guards who have shot a estimated 10,000 people trying to cross the border without papers in the last 10 years.
