Variability in the annual growth rate of carbon dioxide (CO₂) on both global and regional scales is associated with changes in terrestrial carbon sinks. This study presents a comparative analysis of the year-to-year variability in CO₂ growth rates over the last decade from 2013 to 2023 in the Anmyeon-do (AMY: 36.53°N, 126.32°E, South Korea) regional background station and globally recent decade. We fist investigated the influence of the El Niño-Southern Oscillation (ENSO) on CO₂ growth rates. During the strong El Niño event of 2015/2016, both the AMY and global CO₂ growth rates increased by over 10% compared to the last decade average. Conversely, the subsequent La Niña event of 2021/2022 led to a decline of more than 10% in both AMY and global CO₂ growth rates, indicating a similar response of CO₂ growth rates at AMY to ENSO impact as observed globally. The study also focused on the years 2017 and 2019, which exhibited significant year-to-year variability in CO₂ growth rates at AMY relative to the global. In 2017, the global annual CO₂ growth rate aligned with the last decade average, whereas the AMY experienced a 40% reduction, representing a notably larger decrease. Conversely, in 2019, while the global CO₂ growth rate remained consistent with last decade average, AMY recorded a 22% increase. To explore this pronounced year to year variability, we analyzed the optimized terrestrial Net Ecosystem Exchange (NEE) of CO₂ from the NOAA CarbonTracker model. In 2017, the biosphere CO₂ uptake around the Korean Peninsula was 0.27 PgC, the highest in the last decade, while in 2019, it dropped to 0.14 PgC, approximately half of the 2017 level. These findings suggest that the CO₂ growth rates observed in AMY are highly sensitive to terrestrial changes due to temperature and drought conditions around the Korean Peninsula, highlighting the imperative for long-term monitoring to understand the impact of regional climatic characteristics on the carbon cycle amid ongoing climate change.
