Increasing concentrations of co2 in the atmosphere are leading to an increase in global-averaged surface temperatures, an increase in global-averaged ocean temperatures, and to acidification of the earth's oceans. using thermodynamic data in appendix a, and the following conditions for 1950 versus 2015, calculate the concentration of dissolved co2 in ocean water in 1950 versus 2015. ignore the effect of salinity on co2(aq) solubility (i. e., assume yco2 = 1). report your answers as mg/l of co2. (8 pts) (a) 1950 - pco2 = 300 ppmy; tseawater = 16°c (b) 2015 - pco2 = 400 ppmy; tseawater = 17°c
