NODC OHC updated for JFM


Recommended Posts

I wonder what Jonger will have to say to make this data vanish. The post-2003 trend is becoming quite positive even at 0-700m. The 0-2000m trend already was positive.

Pretty much proves the fact the system is still gaining energy. Due to the fact that the deep oceans have such a high thermal capacity, and the fact that they can only attain the added energy via vertical mixing and conduction from the surface, the oceans (at depth) will be much slower to respond to GHG forcing, and *much* farther from equilibrium than the surface. Hence even if we stop emissions completely, warming will continue unabated for some time.

So what do the new data show? Well, it turns out that the energy stored within the ocean (which is 90% or more of the total “global warming” heat), increased significantly. A plot from NOAA is shown above. You can see that the last data point (the red curve), is, literally off the chart. 

The folks at NOAA do a great job updating this graph every three months or so. We can now say that the 2014 Earth had more heat (thermal energy) than any year ever recorded by humans. We can also say that the folks at NOAA will likely have to rescale their graph to capture the new numbers. The NOAA site is updated by Dr. Tim Boyer and can be found here. Click on slide 2 to view the relevant image.

If people want to read a review of ocean heating that is written for a general audience, I suggest our recent peer-reviewed paper which can be found here.

So when we look back on 2014 and the records that fell, it gives us some pause about the so-called pause (hat-tip to Dr. Greg Laden for that phrase). Some people tried to tell us global warming had “paused”, that it ended in 1998, or that the past 15 years or so had not seen a change in the energy of the Earth. This ocean warming data is the clearest nail in that coffin. There never was a pause to global warming, there never was a halt, and the folks that tried to tell you there was were, well, I’ll let you decide. For me, the facts speak for themselves.
