百科知識(shí)視頻之煎蛋小學(xué)堂20 400ppm 世界上規(guī)模比較大的實(shí)驗(yàn)

Hello fellow scientists!Thanks to your active collaboration,our study the world's largest uncontrolled experiment.crossed a historic milestone on May 9,2013,Ahead of schedule,the concentration of carbon dioxide gas in the Earth's atmosphere has reached 400 parts per million.This is a big change from a hundred years ago,when the concentration was just 300 ppm.below which it had stayed for more than 800,00 years.

科學(xué)家們你們好!正由于你們的積極合作 我們的研究，世界上最大的不受控實(shí)驗(yàn)，在2013年5月9日跨過(guò)了一個(gè)新的里程碑，我們提前將地球大氣中二氧化碳濃度，提高到了百萬(wàn)分之四百。和一百年前相比 這是個(gè)極大的變化，當(dāng)時(shí)二氧化碳濃度僅為300ppm，80萬(wàn)年以來(lái)這個(gè)數(shù)字一直保持在300之下。

We've used the most effective methods to increase the levels of CO2 in our atmosphere.burning coal,oil and natural gas,chopping down forests,and surprisingly making cement.In some respects 400 ppm is just an arbitrary figure.an attractively round number like the four-minute mile.or the 7 billion mark for world population.but it indicates that we have reached a new phase of our experiment.

我們采用了最有效的方法來(lái)提高大氣中的二氧化碳濃度：燃燒煤炭 油和天然氣 砍伐森林，還有更令人驚訝的 制造水泥。在某些方面 400ppm只是一個(gè)任意設(shè)定的數(shù)字，一個(gè)吸引人的約整數(shù) 正如每英里四分鐘(速度)，或者是地球人口70億大關(guān)。但這意味著我們已經(jīng)達(dá)到了實(shí)驗(yàn)的新一個(gè)階段。

Each day forward,we go deeper into territory uncharted in human history!After 400ppm who knows what will happen?Actually,our preliminary results give us a pretty good idea.

日復(fù)一日 我們向人類歷史的未知地域探得越深!400ppm過(guò)后 誰(shuí)知道會(huì)發(fā)生什么呢?實(shí)際上 我們的初步結(jié)果已帶來(lái)了比較明確的思路。

We've seen more and bigger floods,fires,droughts,and storms,Melting ice caps and rising sea levels.You may already have experienced some of these yourself,and you can expect more in the future,Please publicize our experiment and tell your friends,family and politicians how important their contributions have been.

我們已經(jīng)目睹了更兇猛更頻繁的洪水 大火和風(fēng)暴。冰蓋在融化 海平面在上升。你可能也已經(jīng)親身經(jīng)歷了當(dāng)中的某些事情，在未來(lái) 你可以指望經(jīng)歷更多這樣的事，請(qǐng)幫忙宣傳我們的實(shí)驗(yàn) 并且告訴你的朋友 家人，以及政客們他們對(duì)實(shí)驗(yàn)的貢獻(xiàn)有多重要。

After all,it is people-like you and me and major corporations-with access to cars,air conditioning supermarkets,and so on who are responsible for the large majority of today's greenhouse gas emissions.

畢竟 是人類 如你我 還有那些大公司。通過(guò)開車 開空調(diào) 去超市購(gòu)物等等，是這些人對(duì)今日排放的大部分溫室氣體負(fù)有責(zé)任。

This global experiment can't continue without your participation.So remember,the next time you let your car idle,leave the Ac on when you're not home.or forget to eat the food you bought...yor're part of something big.

這項(xiàng)全球性的實(shí)驗(yàn)不能沒有你的參與，所以請(qǐng)牢記 下次你讓自己車閑置無(wú)用時(shí)，或是在不在家時(shí)開著空調(diào)，要么忘記吃自己帶的食物，你就是那大計(jì)劃的一部分。
