The competition between anthropogenic aerosol and greenhouse gas climate forcing is revealed by North Pacific water-mass changes
Shi, J.-R., Wijffels, S. E., Kwon, Y.-O., Talley, L. D., & Gille, S. T. (2023). The competition between anthropogenic aerosol and greenhouse gas climate forcing is revealed by North Pacific water-mass changes. Science Advances, 9(38), eadh7746. https://doi.org/10.1126/sciadv.adh7746
The anthropogenic aerosol (AA) effect overwhelms the greenhouse gas (GHG) effect during 1950-1985 in driving salinity changes on density surfaces, while after 1985 the GHG effect dominates. These observations reveal this transition in climate forcing around 1985 and highlight the important role of AA climate forcing on our oceans’ water masses. (Image provided by Jia-Rui Shi)
