New Ocean Heat Content Data is Out

The ocean heat content (OHC) for the 2nd quarter of 2017 has just been published, and it shows strong warming from a year ago.

Data: 0-700 m; 0-2000 m.

OHC for both regions is actually down slightly from a quarter ago, but this seems like the usual occurrence. But they're both up compared to 2Q16:

0-700 m region four-quarter change: +1.8 W/m2
0-2000 m region four-quarter change: +2.3 W/m2

where, again, I spread the heat change over the Earth's entire surface, since almost all (about 93%, plus or minus) of the trapped heat goes into the ocean.

By my calculations, the OHC of the 0-2000 m region -- basically the top half of the ocean -- is accelerating since 1Q2005 at 0.04 ± 0.02 (W/m2)/yr. That uncertainty is 2σ, and doesn't include consideration of autocorrelation.

Here are the graphs. Since OHC is the best measure of a planetary energy imbalance, it's clear the planet has kept warming.

Eclipse traffic

Oregon Dept of Transportation says traffic could be congested in Oregon for up to a week, on I5, the major north-south route here.

Glad I live right under the path of totality. My sister and her family in Portland are coming down, a day early. Sleeping in the back yard.
