A special issue preface: Radiocarbon in the Anthropocene

Area of Science:

• Earth System Science
• Climate Science
• Environmental Science

Background:

• The Anthropocene is characterized by accelerated human-induced changes to the Earth system.
• Anthropogenic greenhouse gas emissions, particularly CO2, are profoundly altering the global carbon cycle.
• Understanding the dynamics of carbon cycle change is critical for predicting future climate scenarios.

Purpose of the Study:

• To highlight the utility of radiocarbon as a tool for investigating carbon cycle perturbations.
• To elucidate the nature, magnitude, and pace of carbon cycle changes in the Anthropocene.

Main Methods:

• Utilizing radiocarbon (¹⁴C) analysis as a tracer for carbon cycle dynamics.
• Examining changes in atmospheric CO2 and other greenhouse gas concentrations.
• Assessing the impact of anthropogenic emissions on the global carbon budget.

Main Results:

• Radiocarbon measurements provide crucial insights into the speed and scale of carbon cycle alterations.
• The study demonstrates how radiocarbon can differentiate between natural and anthropogenic carbon fluxes.
• Evidence presented illustrates the pervasive influence of human activities on carbon reservoirs.

Conclusions:

• Radiocarbon is an invaluable tool for quantifying and understanding carbon cycle changes during the Anthropocene.
• Accurate assessment of carbon cycle dynamics is essential for climate change adaptation and mitigation strategies.
• This research underscores the interconnectedness of human activities, the carbon cycle, and future climate.
