Ocean Acidification

Scientists discuss the impact of the ocean’s changing pH levels.

    I like the video but is anyone able to clarify what is going on around 53secs in?  It looks like a simulation of surface ocean pH dropping from ~3.7 to about 2.7 judging by the accompanying colour scale?  Considering the modern global average pH is around 8.1 and projected to decrease by 2100 but generally not below 7, this seems a little off!

     The scale is correct as labeled, showing acid rain and physically dangerous acids, but yes, it is not synchronized with the colours shown on the accompanying globe. Maybe we could fix that with a bit of editing, to either move the scale up to reflect current ocean conditions, or modify the colours on the map.
