Title:
Exploring terrestrial CO₂ cycle: from soil to karst underground atmospheres

Abstract:
Global warming is caused by an imbalance of the carbon cycle that has surpassed its natural variability due to increased amounts of carbon dioxide (CO₂) in the atmosphere. Soil is a major terrestrial component of the natural carbon cycle, where intensive agriculture contributes significantly to CO₂ fluxes to the atmosphere. However, mineral weathering in and beneath soils represents a natural sink of CO₂, which can mitigate soil CO₂ emissions. This balance is particularly important in karst regions, which cover approximately 10–13% of the continental surface. Due to the complexity of karst systems, it remains unclear whether karst areas act predominantly as sinks or sources of CO₂, representing a significant limitation in accurately assessing global terrestrial CO₂ budgets.

We look forward to your participation.
