Atmospheric CO2 and Climate: Byrd Ice Core, Antarctica

Reconstructions of ancient atmospheric CO2 variations help us better understand how the global carbon cycle and climate are linked. This data set compares CO2 variations on millennial time scales between 20,000 and 90,000 years with an Antarctic temperature proxy and records of abrupt climate change in the Northern hemisphere.

古大气二氧化碳变化的重建有助于我们更深入地理解全球碳循环与气候之间的关联机制。该数据集比较了2万至9万年前千年时间尺度上的二氧化碳变化、南极温度代用指标（proxy），以及北半球气候突变的记录。
