How have reductions in global carbon dioxide emissions during the COVID-19 pandemic influenced aquatic ecosystems through ocean acidification?

CO2 acidification and pandemic situation

“…These results identified positive environmental quality effects in the water bodies beyond CO 2 acidification, which is still a key driver in aquatic ecosystem health, but has been demonstrated as not being the only factor affecting aquatic ecosystem quality. As other authors have pointed out ( Rizvi et al, 2021 ), factors such as terrestrial run-off, ocean upwelling, brownification, and water temperature must be examined in the context of COVID-19 consequences to draw strong conclusions about ocean acidification during the pandemic. They have supported this affirmation and proposal using photosynthetic data, as reported by Le Quéré et al (2020) .…”
