Theroretically at best. The science behind that claim is ridiculously suspect. Since you brought up the oceans; 330ish gigatonnes per year emitted; anthropogenic contribution... under 30 gt. Furthermore, we're at a near historic low for atmospheric CO2. Were the oceans acid in the Jurassic period? Nope; but CO2 was double what it is now.
This graph and associated paper also shows no coupling of CO2 and temperature.. Do some research, see the other side of the discussion, and ask yourself what is more reliable; empirical data, or predictive computer modelling.
p.s. Air quality in N.A. is the best it's been in 150 years, despite the consistent rise in CO2 emissions. Do not confuse a naturally occurring trace gas with harmful compounds such as sulfur dioxide and nitric oxides. Ask Europe how the push for diesel, to reduce CO2, has worked out for their air quality.
