P173翻译
Most scientists no longer doubt that the world is warming up and that humanity has altered climate. They agree that the long-term effects of global warming will be disastrous for the planet and its inhabitants. What is more, climate change won't be a smooth transition to a warmer world. Some regions will be greatly affected by abrupt climate changes. Enormous areas of densely populated land like coastal Florida would become uninhabitable. Hundreds of millions of residents would have to migrate to safer regions. Therefore, it is no surprise that global warming has made its way onto the agenda of world leaders.
