Are the oceans actually cooling?

A friend pointed me to an article D. E. Harrison and Mark Carson "Is the World Ocean Warming? Upper-Ocean Temperature Trends: 1950–2000" Journal of Physical Oceanology, 37(2007), p. 174-187. The authors divided the oceans up into 1 deg squares and looked at the temperature trends. They used grids which contained That article contains a picture of the world's ocean seen below. The authors state:

"Three features stand out from examination of Fig. 8.
First is that almost every 2 x 2 region underwent 20-yr
periods with warming and cooling trends (statistically,
about 95% of the regions change the sign of their trend
sometime throughout the 51-yr period). The ocean neither
cooled nor warmed systematically over the large
parts of the ocean for the entire analysis period
."

An example taken from several sites shows that over the past 30 years the oceans may have been cooling.



Now, it is clear from the above that there hasn't been much warming over the past few decades. And right now, even NASA says the oceans are cooling. Look at the last four years of the oceanic curve in the picture below from .

So much for the hysteria
