…The Ocean Heat Story.
David Stockwell has become interested in determining whether there is any acceleration of ocean heat content.
This is a preliminary look at the data before actually testing the notion of ongoing accleration of ocean heat content rise.
Climate Explorer has NODC data:
Now, I’m not sure I calculated these right but here are the 144 month slopes:
I notice that the recent rates of change are much higher than those befor about 1976-the Great Pacific Climate Shift-when the world and oceans were cooling. But after that, the trends at the begining of that period and the end are very similar-in fact, the recent ones are lower. Now I think you can see why I like to plot data this way-it reveals things about the data that niave fits with polynomials do not. I allows us to say not merely “is there an increase in the rate of change?” but precisely when any change occured. Based on this I so far doubt that century scale data would show any signficant accleration.
