IPCC on acid – if they are virtually certain about ocean acidification, why does X-prize offer a reward for designing a proper ocean pH meter?

Watts Up With That?

The IPCC writes in the “leaked” SPM

It is very likely that oceanic uptake of anthropogenic CO2 results in acidification of the ocean. The pH 44 (see 7) of seawater has decreased by 0.1 since the beginning of the industrial era, corresponding to a 45 26% increase in hydrogen ion concentration. {3.8.2; Box 3.2; FAQ 3.2}

later they say:

Earth System Models project a worldwide increase in ocean acidification for all RCP scenarios. The 1 corresponding decrease in surface ocean pH by the end of 21st century is 0.065 (0.06 to 0.07)12 for 2 RCP2.6, 0.145 (0.14 to 0.15) for RCP4.5, 0.203 (0.20 to 0.21) for RCP6.0, and 0.31 (0.30 to 0.32) for 3 RCP8.5 (see Figures SPM.6 and SPM.7). {6.4.4}

Here are the figures cited, SPM6C and SPM7D:



Gosh, just look at all that scary, red, burning, “acid”. What they fail to note is that the oceans still haven’t…
