Why AI pH maps can look accurate while getting ocean carbon chemistry wrong: the REACT preprint, explained

A new arXiv preprint, REACT, argues that AI models reconstructing sea surface pH can minimize visible error while violating the carbon chemistry beneath. Its carbon-first framework reports smaller pH error and better chemical consistency, but only on simulation data.
