The ocean, our super hero ? Will those vast expanses of salty water, reaching down to lightless depths, be our planet’s saviour ? In an interview with Eos magazine, none other than our own Phil Renforth (yes, the same with whom we walked the rugged shores of Hawai’i), explains in a very accessible way how the ocean may assist us in combating effects of climate change. More specifically, Phil explains how raising the ocean’s alkalinity -it’s acid buffer capacity- may help to sequester more CO2 from the atmosphere. This is of course a shared research interest, as we collaborate on several fronts. The interview in Eos was done to accompany a scientific article Phil published in the journal Reviews of Geophysics, on the same subject. It would be silly to repeat what Phil has to say, so I invite you sit down and read it here. Enjoy !
