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 climate
change, it is the latest in a series 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.»
Elsewhere on this site there is a graph of overall
ocean heat content which is building indicating that while the sst is decreasing slightly the overall
ocean is warming, It is likely that this overall
ocean warming which has nothing to
do with
changes to the atmospheric
temperature because it is the sea surface and not the
deep ocean that is in contact with the atmosphere is what is resulting in the overall rise in atmospheric CO2 concentration which is currenly increasing at 2ppmv / year.
HS12 assume that
deep ocean temperature change was similar to global mean surface
temperature change for Cenozoic climates warmer than today, but this relationship
does not hold true for colder climates.
What
did they think 60 years ago about the rate of
deep ocean circulation, was anything said about what they thought on
temperature changes in the abyss?
