一張圖告訴你：2100年的地球將有多熱？

It looks like the world could be a much hotter place by the end of the century.
貌似到本世紀末地球上溫度會比現在高很多。

New data released by Nasa scientists is revealing how temperature and rainfall patterns around the world may change by the year 2100.
美國國家航空航天局科學家發佈的新數據顯示到2100年爲止全球氣溫和降水模式會如何改變。

Using climate change predictions based on increasing levels of carbon dioxide, the data reveals what may happen to the climate in individual towns and cities.
利用基於二氧化碳水平所預測到的氣候變化，該數據揭示了每個鄉鎮和城市氣候將如何變化。

Much of the data is still in raw form for now to allow scientists to run models on a daily timescale. However, a map of the world released by Nasa, which shows the predicted temperature for July 2100, provides some clues for what the world may look like.
目前很多仍是原始數據，以便科學家能以天爲單位運行模型。然而，美國國家航空航天局發佈了一幅世界地圖，展示了2100年7月份的預計氣溫，爲世界未來的發展提供了一些線索。

By that time, carbon dioxide levels in the atmosphere will have reached 935 parts per million, meaning the gas comprises nearly 0.1 per cent of the atmosphere.
到那時，大氣中二氧化碳水平將達到每百萬935單位，這意味着大氣中的二氧化碳含量將達到近0.1%。

Earlier this year carbon dioxide levels reached 400 parts per million.
今年早些時候，二氧化碳水平達到每百萬400單位。

If by the end of the century carbon dioxide in the atmosphere more than doubles, much of Africa, South America and India will endure average daily maximum temperatures of more than 45°C.
如果到本世紀末大氣中二氧化碳水平變成現在兩倍多，非洲、南美和印度大部分地區將遭受超過45°C的日平均最高氣溫。

Jerusalem, New York, Los Angeles and Mumbai could see summer temperatures reaching these levels too.
耶路撒冷、紐約、洛杉磯和孟買夏季氣溫也會達到這一水平。

Londonwill experience temperatures in the mid 20s and Paris could see its July temperatures reaching the low 30s.
倫敦溫度將達25度左右，而巴黎7月的溫度將接近30多度。

Ellen Stofan, chief scientist at Nasa, said: 'Nasa is in the business of taking what we've learned about our planet from space and creating new products that help us all safeguard our future.
美國國家航空航天局首席科學家艾倫·斯托芬說：“美國國家航空航天局正利用我們從太空了解到的關於地球的知識研究出新的成果，來幫助我們所有人守護未來。”
