 It's Official: Atmospheric CO2 Just Exceeded 415 ppm For The First Time in Human History 官方消息：人類歷史上大氣二氧化碳濃度首次突破百萬分之415。 Yet another alarming milestone of humanity's damaging effect on the environment has now officially been reached-crossing a barrier into a hot, polluted future like the planet hasn't witnessed in millions of years. 人類對環(huán)境造成的破壞又達(dá)到了一個令人擔(dān)憂的新高度，已經(jīng)跨越門檻走向一個地球數(shù)百萬年來未曾見過的炎熱的被污染的未來。 Sensors in Hawaii recorded Earth's atmospheric concentration of carbon dioxide (CO2) passing 415 parts per million (ppm) for the first time since before the ancient dawn of humanity. 據(jù)夏威夷的傳感器記錄，地球大氣中的二氧化碳(CO2)濃度自人類遠(yuǎn)古時期至今首次突破了百萬分之415。 Last Saturday, CO2 concentration recorded at the Mauna Loa Observatory in Hawaii by researchers from the Scripps Institution of Oceanography hit 415.26 ppm – the latest in a dire series of climatic thresholds being breached by a human society that refuses to relinquish the conveniences afforded by fossil fuels. 上周六，斯克里普斯海洋研究所的研究人員在夏威夷莫納羅亞天文臺記錄的二氧化碳濃度高達(dá)百萬分之415.26，人類社會因為拒絕放棄燃燒化石燃料帶來的便利而突破了一系列氣候危險閾值，這次又刷新了一個記錄。 "This is the first time in human history our planet's atmosphere has had more than 415 ppm CO2," meteorologist Eric Holthaus tweeted. 氣象學(xué)家Eric Holthaus在推特上寫道：“這是人類歷史上首次地球大氣層中二氧化碳濃度突破百萬分之415?！?/p> "Not just in recorded history, not just since the invention of agriculture 10,000 years ago. Since before modern humans existed millions of years ago. We don't know a planet like this." “這個首次不僅僅是在歷史記錄上，也不僅僅是1萬年前農(nóng)業(yè)出現(xiàn)以后，而是現(xiàn)代人類出現(xiàn)之前的百萬年前至今。以前地球從未出現(xiàn)過這種情況?！?/p> It was only a few years ago that carbon pollution in the atmosphere soared past 400 ppm, and it didn't take long much longer to reach 410 ppm (in 2017). 僅僅幾年前大氣中碳污染剛剛飆升至百萬分之400，之后沒過多久(2017年)就達(dá)到了百萬分之410。 In fact, with this record-breaking surge in atmospheric carbon poisoning the skies and trapping Earth's heat, scientists knew hitting 415 ppm in 2019 was all but inevitable. 其實科學(xué)家也知道，有飆升至破紀(jì)錄的大氣碳濃度破壞著天空，給地球保溫，在2019年碳濃度達(dá)到百萬分之415幾乎是不可避免的。 文章來源：滬江英語 圖片來源：高品圖像 |
