Research shows that deserts can capture carbon dioxide (CO) through processes not involving photosynthesis, but inconsistencies in measurement methods create uncertainty in these findings.
A study in the Taklimakan Desert indicated that if certain measurement errors aren’t corrected, the carbon sequestration potential of shifting sand could be exaggerated.
Results show that shifts in soil temperature influence CO exchange, with the sand acting as a carbon source in warmer months and a sink in cooler ones, demonstrating that deserts are significant in the global carbon cycle.
