大气层里的二氧化碳突破历史新高

　　Its Official: Atmospheric CO2 Just Exceeded 415 ppm For The First Time in Human History官方消息：人类历史上大气二氧化碳浓度首次突破百万分之415

　　Yet another alarming milestone of humanitys damaging effect on the environment has now officially been reached – crossing a barrier into a hot, polluted future like the planet hasnt witnessed in millions of years.人类对环境造成的破坏又达到了一个令人担忧的新高度，已经跨越门槛走向一个地球数百万年来未曾见过的炎热的被污染的未来。

　　Sensors in Hawaii recorded Earths atmospheric concentration of carbon dioxide (CO2) passing 415 parts per million (ppm) for the first time since before the ancient dawn of humanity.据夏威夷的传感器记录，地球大气中的二氧化碳(CO2)浓度自人类远古时期至今首次突破了百万分之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员在夏威夷莫纳罗亚天文台记录的二氧化碳浓度高达百万分之415.26，人类社会因为拒绝放弃燃烧化石燃料带来的便利而突破了一系列气候危险阈值，这次又刷新了一个记录。

　　This is the first time in human history our planets atmosphere has had more than 415 ppm CO2, meteorologist Eric Holthaus tweeted.气象学家Eric Holthaus在推特上写道：“这是人类历史上首次地球大气层中二氧化碳浓度突破百万分之415。”

　　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 dont know a planet like this.“这个首次不仅仅是在历史记录上，也不仅仅是1万年前农业出现以后，而是现代人类出现之前的百万年前至今。以前地球从未出现过这种情况。”

　　It was only a few years ago that carbon pollution in the atmosphere soared past 400 ppm, and it didnt take long much longer to reach 410 ppm (in 2017).仅仅几年前大气中碳污染刚刚飙升至百万分之400，之后没过多久（2017年）就达到了百万分之410。

　　In fact, with this record-breaking surge in atmospheric carbon poisoning the skies and trapping Earths heat, scientists knew hitting 415 ppm in 2019 was all but inevitable.其实科学家也知道，有飙升至破纪录的大气碳浓度破坏着天空，给地球保温，大气层里的二氧化碳突破历史新高在2019年碳浓度达到百万分之415几乎是不可避免的。
