Global sea surface temps only warming at 0.06°C per decade since 1950
Global sea surface temperature records suggest only modest warming in the 20th Century, and so far in the 21st Century.
According to Dieng et al., 2017, global sea surface temperatures cooled slightly (-0.006°C/decade) from 2003 to 2013. This reduced the overall 1950-2014 warming rate to 0.059°C per decade.

The NCAR/HadCRUT4 global SST record from buoys and ARGO floats also show only modest warming in the last three decades. The natural 2015-’16 Super El Nino event is mostly responsible for the overall increasing rate.
Since 1871 there has been only modest warming in the Pacific and Atlantic (Zanna et al., 2019). Perhaps the Indian Ocean has a clearly detectable warming trend.

According to the Oceans 2k (2015) collection of globally reconstructed sea surface temperatures over the last 2000 years, there has been no alarming rise in temperatures that stands out (like a hockey stick) during the 20th century either.

On a deeper note, from 1955 to 2010 the 0-2000 m ocean only warmed 0.09°C (Levitus et al., 2012).

So why, exactly, should we be panicked and alarmed about any of this?

Hi PSI Readers,
“According to Dieng et al., 2017, global sea surface temperatures cooled slightly (-0.006°C/decade) from 2003 to 2013. This reduced the overall 1950-2014 warming rate to 0.059°C per decade.”
Evidence of what usually happens when one begins to average variable data. The the precision of the averaged value becomes far greater than the precision with which the data was actually measured.
Have a good day, Jerry
