After my last post about the surface warming of the ocean, entitled “How Global Warming Isn’t“, I got to thinking about the warming of the upper part of the ocean. So I got the data for the ocean heat content (OHC) of the top 700 metres of the ocean from the marvelous site, KNMI. If you look under “Monthly Observations” you’ll find a host of most fascinating datasets. Under “Heat Content” on that page, you’ll find the National Oceanic Data Center (NODC) 0-700 metre depth OHC data. And down at the very bottom of that page is a link that will download a 196 megabyte gridded NetCDF file containing the data that I used. (Big file, click at your own risk.)

And what did I find? Well, I’m a visual kind of guy. I mean, I can do the math, but it only makes sense when it comes up as a picture on the silver screen. So here are my graphics. I’m interested in the changes in the oceanic heat content, so these are two views of those trends.

This is the bottom line. If the world’s creatures, both on land and at sea, were as temperature-sensitive as the alarmists would have us believe, those beings (and we humanoids as well) all would have gone extinct long ago. And near as I can tell, that hasn’t occurred … at least yet.
