An article about ocean temperature history/modeling has this plot:
Where the units are given as cK
.
cK
does not seem to be a standard temperature unit and Google searches return millions of results that don't seem relevant.
While it might be "fun" if the temperatures shown were Kelvin, centi-Kelvins, or even Celsius, that seems unlikely as we are all still alive.
So, what is cK
as shown on the graphic, and how do you convert the temperatures shown to degrees Celsius?
If the axis is really some delta temperature, what is the zero point?
