A 1.46-million-year record of atmospheric CO2 from sedimentary leaf wax

A great deal of effort is now focused on reconstructing atmospheric CO2 during periods of lower polar ice volume to better constrain carbon cycling under conditions similar to...

当前已有大量研究工作聚焦于重建极地冰量较低时期的大气二氧化碳（CO₂）浓度，以期在类似的环境条件下更严谨地限定碳循环过程。
