The Climate Lab That Sits Empty

It is a marker of omission: Carbon dioxide produced from fossil fuels contains no carbon 14 at all.
As the United States retrenches, though, China is already heavily investing in atmospheric monitoring, including carbon 14 research.
There is no evidence for this, but a clear signal from carbon 14 could help expose any reporting errors.
The most likely one is that oceans or soils are absorbing less carbon dioxide than in the past.
The accelerator mass spectrometer allows scientists to measure carbon 14, a radioactive isotope that is critical to identifying carbon dioxide released by burning fossil fuels.
