An increase of just 2°C in global temperatures could make the world considerably drier and more desert-like, new research has warned. 最新研究提醒称，全球气温升高2摄氏度，就会显著增加干旱程度，使地球荒漠化程度加剧。 More than a quarter of the world's land surface, home to more than 1.5 billion people, would become more arid and droughts and wildfires could be widespread. 届时，超过四分之一的陆地表面（15亿多人口的家园）将会更加干旱荒芜，野火肆虐。 Limiting global warming to 1.5°C (2.7°F) would dramatically reduce the percentage of the Earth's surface affected, scientists found. 科学家发现，将全球气候变暖升温控制在1.5摄氏度以内将显著降低地球表面受影响的比例。 |
