若氣溫再升高2度 將導致四分之一土地變沙漠

An increase of just 2°C (3.6°F) in global temperatures could make the world considerably drier and more desert-like, new research has warned.

一項最新研究警告稱，氣溫只升高2攝氏度（3.6華氏度），就會使全球的乾旱程度和荒漠化程度明顯加劇。

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.

屆時，超過四分之一的陸地表面（超過15億人口的家園）將會更加乾旱荒蕪，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.

科學家發現，將全球氣候變暖升溫控制在1.5攝氏度以內（2.7華氏度）將顯著降低地球表面受影響的比例。

Aridification would emerge over 20 to 30 per cent of the world's land surface by the time the global temperature change reaches 2°C (3.6°F)', said Dr Manoj Joshi from the University of East Anglia's School of Environmental Sciences and one of the study's co-authors.

這項研究報告的合著者、東安格利亞大學環境科學學院的馬努基·喬西博士稱：“如果地球升溫2攝氏度（3.6華氏度），20%到30%的地表會幹旱化。”

The research team studied projections from 27 global climate models and identified areas of the world where aridity will substantially change.

研究小組利用27個全球氣候模型預測，確定出了嚴重受到乾旱影響的地區。

The areas most affected areas are parts of South East Asia, Southern Europe, Southern Africa, Central America and Southern Australia. These areas are home to more than 20 per cent of the world's population - that's over 1.5 billion people.

受影響最大的區域有東南亞、歐洲南部、非洲南部、中美洲和南澳的部分地區。這些地區的人口占全球人口的20%以上--也就是超過15億人。

The Paris Agreement, which was first signed in 2015, it is an international agreement to control climate change. It hopes to hold the increase in the global average temperature to well below 2°C (3.6?F) 'and to pursue efforts to limit the temperature increase to 1.5°C (2.7°F)'.

2015年首次簽署的《巴黎氣候協定》是一份控制氣候變化的國際協議。該協定希望將全球平均增溫控制在2攝氏度（3.6華氏度）以下，並努力將增溫控制在1.5攝氏度（2.7華氏度）以下。

It seems the more ambitious goal of restricting global warming to 1.5°C (2.7°F) may be more important than ever, according to the new findings.

根據這項新的發現，這個更具挑戰性的目標--將增溫控制在1.5攝氏度（2.7華氏度）以下，看起來比以往任何時候都要重要。
