根据古南极冰分析，二氧化碳的增长速度比过去 50,000 年快 10 倍。 10x faster CO2 increase than past 50,000 years, based on ancient Antarctic ice analysis.
研究人员通过对古代南极冰层进行详细的化学分析发现，如今大气中二氧化碳 (CO2) 的增加速度比过去 5 万年中的任何其他时期都要快 10 倍。 Researchers have discovered that today's rate of atmospheric carbon dioxide (CO2) increase is 10 times faster than at any other point in the past 50,000 years, based on a detailed chemical analysis of ancient Antarctic ice. 对地球过去气候突变期的新认识为了解当今气候变化的潜在影响提供了宝贵的见解。 This new understanding of abrupt climate change periods in Earth's past offers valuable insight into the potential impacts of climate change today. 俄勒冈州立大学的主要作者凯瑟琳温特表示，当今二氧化碳的变化速度是前所未有的。 The rate of CO2 change today is unprecedented, according to lead author Kathleen Wendt from Oregon State University.
