A process-based carbon isotope biogeochemistry model substantially reduces uncertainty in regional and global estimates of the stable carbon isotopic composition of methane emissions from wetlands and suggests rising atmospheric concentrations are du

REMINISCING ON THE USE AND ABUSE OF 14C AND 13C IN ATMOSPHERIC CO2

Autor: Pieter Tans

Publikováno v: Radiocarbon. 64:747-760

We are observing a dramatic increase of CO2 in the atmosphere, unprecedented in the last several million years. Carbon isotopic ratios have been very useful in helping to untangle the respective roles of anthropogenic emissions and sources/sinks of C

The carbon cycle response to two El Nino types: an observational study

Publikováno v: Environmental Research Letters, Vol 13, Iss 2, p 024001 (2018)

We analyze monthly tropical near surface air temperature and Mauna Loa Observatory carbon dioxide (CO _2 ) data within 1960–2016 to identify different carbon cycle responses for two El Nino types: El Ninos originating in the central tropical Pacifi

COS-derived GPP relationships with temperature and light help explain high-latitude atmospheric CO

In the Arctic and Boreal region (ABR) where warming is especially pronounced, the increase of gross primary production (GPP) has been suggested as an important driver for the increase of the atmospheric CO

Severe droughts in the Northern Hemisphere cause a widespread decline of agricultural yield, the reduction of forest carbon uptake, and increased CO2 growth rates in the atmosphere. Plants respond to droughts by partially closing their stomata to lim
