Oceans are warming dramatically faster, new study warns
Since 1970, the ocean has warmed 40 percent more than previous estimates, scientists say

Now I am no climate scientist. But even I know why energy content is the more relevant parameter and not temperature, and I’m sure Roy knows too, but isn’t saying because it doesn’t fit the narrative he is spinning.It also raises the question of why energy content? We don’t do that for the atmosphere. Instead, we use what is measured — degrees. The only reason I can think of is that the ocean temperature changes involved are exceedingly tiny, either hundredths or thousandths of a degree C, depending upon what ocean layer is involved and over what time period.
If it’s unflattering, it’s only because the +40% claim was frankly dishonest alarmismTypical of Roy Spencer to portray in the facts in the most unflattering way possible for other climate researchers. One example of his stretching the truth is this:
Why did you say he was stretching the truth and presenting in the most unflattering way when he was just presenting the real facts. The authors referenced the IPCC but then chose to fabricate their own baseline by including what the IPCC had said was wrong.Alarmism? Really? If one is not alarmed by an 11% increase in the rate of ocean warming,
How is the amount of energy transferred into the ocean measured? How is that calculation done? If I say the amount of increased energy absorbed by the ocean is one zetajoule how would I know that…except by comparing the temperature now with the temperature before? So if we have to start with the temperature increase, which is in units (degrees C) everyone can understand, what is the reason to convert those into units (zetajoules) that even scientists would struggle with?The reason is that in air-water interaction, the thing that is conserved is energy , not temperature. The interaction goes both ways. Energy is transferred into the ocean when the air is warmer and energy is transferred out of the ocean when the air is cooler. The factor that determines how much temperature responds to energy is called “specific heat.” It is not an esoteric concept. “Specific heat” is taught in high school physics. But why did Roy say “ The only reason I can think of ” when he knows the real reason very well?
Do you really want to find out how scientists can measure heat content of oceans? If so, become a climate scientist, do the research, and find out. Do not challenge random forum participants like me to obtain this information.LeafByNiggle:![]()

These are simple concepts, as you said they are taught in high school. Specific heat is (more or less) a constant for a particular substance. Heat is energy. To measure the amount of energy added to a substance one needs to know the amount of the substance (its mass), its specific heat (a constant), and the temperature change. That is, to know how much heat is added to a system you have to be able to measure the temperature change. Then you multiply that times the mass (in this case of the ocean) times the specific heat of sea water…which varies depending on pressure and salinity, so you have to calculate all that as well. You can go through that very complex (estimated) calculation to report the energy added to the ocean in a value (zetajoules) that no one can really fathom, or you can do the simple thing and report the increase in temperature which everyone can immediately grasp.Do you really want to find out how scientists can measure heat content of oceans? If so, become a climate scientist, do the research, and find out. Do not challenge random forum participants like me to obtain this information.
Again, lack of measurement history rears its inconvenient head.What I find inappropriate is presenting of guesses on the energy stored as reliable fact. Before the argo buoys were deployed (early 2000s), we were not sampling broadly and consistently below the surface. Their estimates on heat storage 50+ years ago are a complete swag easily tweaked to give the results they want.
or do the simple thing and report an obviously minuscule (but readily understandable) temperature change
I am not sure how the scientists baseline the heat content. But the point that you make responds nicely to @Ender: Oceans may have some value of temperature at a specific location and depth; heat content integrates over that position-to-position variation, in a way that is far better than reporting an average temperature.we were not sampling broadly and consistently below the surface
Here is a discussion/paper on the issues of collecting ocean temp via travelling ships, done for over 100 years.What year did we start recording temperatures of the oceans ?
