The whole issue is that any level above what is often called the «effective radiating level» (say, at ~ 255 K on Earth) should start to cool as atmospheric CO2 increases, since the layers above this height are being shielded more strongly from upwelling radiation... except not quite, because convection distributes heating higher than this level, the stratosphere marks the point where convection gives out and there is high static stability.

These ocean upwelling conditions occur beneath a complementary downwelling branch of the atmosphere's Hadley circulation — a planetary - scale flow pattern in both hemispheres that takes humid air ascending at low latitudes, heats and desiccates it in deep precipitating tropical clouds, and then sinks it at midlatitudes, where it is considerably warmer and drier than it was.

However, the conditions predicted for the open ocean may not reflect the future conditions in the coastal zone, where many of these organisms live (Hendriks et al. 2010a, b; Hofmann et al. 2011; Kelly and Hofmann 2012), and results derived from changes in pH in coastal ecosystems often include processes other than OA, such as emissions from volcanic vents, eutrophication, upwelling and long - term changes in the geological cycle of CO2, which commonly involve simultaneous changes in other key factors affecting the performance of calcifiers, thereby confounding the response expected from OA by anthropogenic CO2 alone.
