就是说1840年的大气二氧化碳基准浓度未必是280ppm，而人类精确测定大气二氧化碳浓度起始于1959年（50年前）。

作者在文章第22节的描述很有意思：

[22] Another finding is that reducing the land use emissions

by a scalar causes total emissions to be more consistent

with a model of a constant airborne fraction. It is

difficult to rate this as a strong indication that land use

emissions are systematically overestimated, as it depends on

the validity of the statistical model. The possibility, however,

presents itself and, given the evidence from oxygen

data [Bopp et al., 2002], would mean that a larger proportion

of emissions is taken up by the ocean than what has

been previously assumed. The analysis also shows that

recent trends after 2000 can be explained by re-scaling land

use emissions within their uncertainty ranges.
