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.
一篇有关海洋棘皮生物海星海胆等固定二氧化碳的能力相当支持了此文作者的观点。
