Bangladesh is among the countries which are at the greatest risk of food insecurity due to weather extremes caused by climate change, a global study suggests.
Researchers led by the University of Exeter in the UK examined how climate change could affect the vulnerability of different countries to food insecurity - when people lack access to a sufficient quantity of affordable, nutritious food.
The study, published in the journal Philosophical Transactions of the Royal Society A, looked at 122 developing and least-developed countries, mostly in Asia, Africa and South America.
The countries at the greatest vulnerability to food insecurity when moving from the present-day climate to 2 degrees Celsius global warming are Oman, India, Bangladesh, Saudi Arabia and Brazil, researchers said.
Limiting global warming to two degrees Celsius will not prevent destructive and deadly climate impacts, as once hoped, dozens of experts concluded in a score of scientific studies released Monday.
That's bad news for 500 million people living in "highly vulnerable" low-lying deltas, mainly in Asia, along with some 400 million people in coastal cities, many of which are already sinking due over-construction or collapsing water tables.
Even in a 2C world, the number of people affected year by flooding could approach 200 million by 2300, the study calculated.
