We don't have volcanoes. But any other natural disaster you think of, we have it. The rivers swell with summer monsoons, filling Bangladesh's vast flood-plain and submerging a quarter to a third of the land in a typical year — and up to two-thirds in the worst of years. Several cyclones usually tear through the heart of the country each year, drowning people in storm surges and ripping up trees and homes. Less sudden calamities — droughts in the country's few highland areas, erosion of the river banks and coastlines — also rob people of food and land.

Climate change will almost certainly make these disasters worse, threatening to reverse the country's progress. Hurricanes in this region have gotten stronger in recent decades, and continued warming in the Indian Ocean could see the trend continue, some researchers predict. Monsoon rainfall is likely to increase and to fall in more intense bursts, making the annual floods broader, deeper and longer, and this could increase river erosion, too. Farmers are already reporting changes in the growing seasons. More erratic weather is making it hard for them to grow crops on the schedules that worked in the past. And then there's the danger of the encroaching sea, which threatens to submerge a substantial part of the country, to worsen monsoon floods and to help storm surges clear protective embankments.
