内容摘要：Off the coast of Nigeria, one of the world’s largest oil production ships, called the Bonga, was taking oil from a field on the ocean floor and transferring it to a tanker ship. Such transfers are routine in the offshore oil industry, but something went wrong on the Bonga, owned by energy giant Shell.

Each year, natural disasters force an average of 21.5 million people from their homes around the world, according to the U.N. High Commissioner for Refugees. And scientists predict migration will grow as the planet gets hotter. Over the next 30 years, 143 million people are likely to be uprooted by rising seas, drought, searing temperatures and other climate catastrophes, according to the U.N.'s Intergovernmental Panel on Climate Change report published this year.Still, the world has yet to officially recognize climate migrants or come up with formalized ways to assess their needs and help them. Here’s a look at climate migration today.
