Fig. 4: Decadal trends in ΔfCO2 in the North (>30°N, excluding the Arctic Ocean).
From: Constraining the trend in the ocean CO2 sink during 2000–2022
Comparison of the measured decadal trend in ΔfCO2 from SOCAT (green dots) with that of the fCO2-product ensemble (blue box-plots and dots) and of the GOBM ensemble (grey box-plots and dots). The box-plots display: the median, the lower and upper quartiles, and the minimum and maximum values that are not outliers. The trends are calculated from median annual values for the North region. On the left, fCO2-products and GOBMs were subsampled at SOCAT locations, while on the right, they were not subsampled, and the value for the North region as a whole is shown. fCO2-product and GOBM data credit: Global Carbon Budget 2023, licensed under Creative Commons Attribution 4.0 International (https://creativecommons.org/licenses/by/4.0/deed.en), no changes were made.
