A collection of useful numbers for quantifying the impacts of the human presence on Earth.Annual increase in ocean surface H+ concentration
WaterOceans & SeasThis quantity comes from a time series measurement and the most recent value (1985-2018) is reported.
Value: | 0.36 ± 0.03 % | |
HuID: | 19394 | |
Relevant Year(s): | 1985-2018 | |
Summary: | The annual increase for 2017-2018 is ≈ 0.2 %. The average annual increase for the period 1985-2018 is ≈ 0.4 %. See Fig 2 on source website. Values are reported as global averaged ocean surface pH. Yearly percent change in H+ concentration can be calculated as [10-∆pH - 1] x 100. | |
Method: | Reported value is the mean and standard error for year-to-year changes in [H+] from 1985 - 2018. | |
