每日一看(1)---Global warming is epic, long-term study says


好，今天來關心一下全球暖化這個老掉牙的話題吧！雖然大家都知道節能減碳是最恆久、最根本改善的方式，但要完全做到似乎遙不可期。我們究竟能做些什麼呢？廢話不多說，直接來看以下的新聞。本篇選自CNN，先看前面的部份吧。

Global warming is epic, long-term study says

研究表示，全球暖化始終如影隨形，未曾消失

 (CNN) -- Global warming has propelled Earth's climate from one of its coldest decades since the last ice age to one of its hottest -- in just one century.

A heat spike like this has never happened before, at least not in the last 11,300 years, said climatologist Shaun Marcott, who worked on a new study on global temperatures going back that far.

"If any period in time had a sustained temperature change similar to what we have today, we would have certainly seen that in our record," he said. It is a good indicator of just how fast man-made climate change has progressed.

A century is a very short period of time for such a spike.

(美國有線電視新聞網)---自上次冰河期，全球暖化已將地球溫度從寒冷推向熾熱---而這個過程只花了一世紀。

氣象學家Shaun Marcott表示，今日的極熱現象，至少在過去一萬一千三百年間從未發生。而這位學者，目前正研究自冰河時期至今的地球溫度變化。

Marcott說：「如果地球每一期的溫度變化都和今日相仿，我們當然可以輕易察覺」。這句話正好指出了人們如何快速地刺激全球暖化，改變全球氣候。

一個世紀能發生如此的遽變，是快得驚人的。

It's supposed to be cold

應該降溫才是

The Earth was very cold at the turn of the 20th century. The decade from 1900 to 1909 was colder than 95% of the last 11,300 years, the study found.

Fast forward to the turn of the 21st century, and the opposite occurs. Between 2000 and 2009, it was hotter than about 75% of the last 11,300 years.

If not for man-made influences, the Earth would be in a very cold phase right now and getting even colder, according the joint study by Oregon State University and Harvard University. Marcott was the lead author of the report on its results.

To boot, the range of temperatures from cold to hot produced since the industrial revolution began are about the same as the 11,000 years before it, said Candace Major from the National Science Foundation, "but this change has happened a lot more quickly."

剛進入20世紀時，地球的溫度仍然不高。研究發現，1900至1909的十年間，地球溫度甚至比過去的一萬一千三百年還要低95%。

然而一到21世紀，就發生了大逆轉。在2000年和2009年間，全球氣溫比過去一萬一千三百年要高出75%。

美國奧勒岡州立大學和哈佛大學指出，如果沒有人為干擾，地球現在仍處於寒冷期，甚至更冷。而Marott先生，正是這項研究的領導。

任職於美國國家科學基金會的Candace Major表示，自工業革命以來，全球氣溫變化的幅度和過去一萬一千年一樣，「但這過程發生得太快了。」
