Radiocarbon (14C) is a unique and important tool for understanding carbon cycle in the nature, and its use can be significantly enhanced where reliable historical atmospheric Δ14CO2 records can be established. In China, continuous atmospheric Δ14CO2 records since the 1950s are scarce, a period...
It has been speculated that the partial pressure of carbon dioxide (pCO2) in shelf waters may lag the rise in atmospheric CO2. Here, we show that this is the case across many shelf regions, implying a tendency for enhanced shelf uptake of atmospheric CO2. This result is based on analysis ...
The increase in atmospheric CO2 observed since the 1950s is most likely dominated by anthropogenic CO2 emissions, which are twice as large as that needed to explain the observed rise. As I haveshown before, a simple CO2 budget model driven by (1) estimates of global yearly anthropogenic CO2 ...
We present a compilation of tropospheric 14CO2 for the period 1950-2010, based on published radiocarbon data from selected records of atmospheric CO2 sampling and tree-ring series. This compilation is a new version of the compilation by Hua and Barbetti (2004) and consists of yearly summer data...

We consider 1960 to be a reasonable basis for compensation given that scientific understanding of the influence on atmospheric CO2 and temperature from burning fossil fuels was well understood32,33,34, and beginning to be communicated to the general public35, by the 1950s. Notably, we agree ...

aStarting in the late 1950s with the groundbreaking research of Roger Revelle and Charles Keeling, scientists have long been aware of the essential role played by the ocean in mitigating the impact of elevated atmospheric carbon dioxide (CO2) levels. Ice core record measurements of carbon dioxide...
To continue the example of global warming, ultraviolet sunlight passes through CO2, warming the earth's surface. Infrared heat radiates back into the atmosphere, warming greenhouse gases (GHGs) such as CO2 and radiating back to the earth (the greenhouse effect). As the concentration of GHGs rise...
