In the paper Gray makes many extravagant claims about how supposed changes in the THC accounted for various 20th century climate changes («I judge our present global

He later
continued: «Now that
ocean temperatures are considerably

Is it not the case that if the relative lack

Terrell Johnson, reporting on a recent NASA publication concluding that deep
ocean temperatures have not increased since 2005 (http://www.weather.com/science/environment/news/deep-
ocean-hasnt-warmed-nasa-20141007): «While the report's authors say the findings do not question the overall science

of findings that show global
warming to have slowed considerably during the 21st century, despite
continued rapid growth in human - produced greenhouse gas emissions during the same time.»
The fact that you don't understand the mechanisms
of how increased CO2
warms the
oceans is irrelevant, since the heat content
of the
oceans is increasing (and, thus, the planet, as a whole has
continued warming despite your «hiatus»).
But even if CO2 were to stop increasing tomorrow, that extra 100ppm will remain there for many, perhaps hundreds

@ 48 If your speculation is correct, I assume that another consequence would be that, if / when concentrations
of greenhouse gases start to drop, corresponding reductions in surface

ocean will gradually make its way to the
ocean surface, and
continue to
warm the atmosphere for decades, if not longer.
