Warren Cornwall, a freelance journalist and contributing correspondent to Science magazine, traveled to Bangladesh for three weeks to investigate how the country is preparing its coastal areas to deal with climate change. Much of the country is a low-lying river delta created by three huge rivers, the Brahmaputra, the Ganges, and the Meghna. Because the area is so low and flat, it's particularly vulnerable to rising sea levels. It's also in the path of cyclones coming from the Bay of Bengal, and there are concerns that these storms, and the floods they cause, will get more intense as the climate changes.
