Is there any unprecedented ocean heat content?

Posted at: 2015-03-12 
According to Rosenthal et al 2013, the answer is no.

One of the most common and reliable ways of measure past thermal conditions is to measure the 18O and 16O (different isotopes of oxygen) found in the shells of animals that build with calcium carbonate. In colder time periods the shells contain more 18O and in warmer periods the ratio is more skewed towards 16O.

Ocean temperature affects what grows where in the ocean, how much dissolved oxygen the water holds (warmer water, less oxygen) and, to a certain amount, acidity, although the latter is more closely associated with CO2 content.

Each of these things leaves a very distinct record in the ocean floor sediments that can be read like any other stratigraphic sequence, or like tree rings.

Using these methods and looking at both ocean and land based lines of evidence we can build up a pretty long record of ocean temperatures. This record, taken from these an other lines of evidence suggest that the ocean is warming.

Look at the RealClimate blog: http://www.realclimate.org/

It is more of the most reputable sources for accurate, unspun climate information and is written by scientists, not by political and news pundits.

If you fill up a large tub of water with very hot water

it will be cool by the end of the day . It does not stay hot.

The Oceans have many currents under the surface that would

circulate the minor heat away .

Boil some water and pour it into a lake Where did the heat go?

Composite ocean temperature has always been difficult to gauge. It has only been since about 2003 we have been able to get good data from the entire ocean from the Argo buoy system. And they say the oceans are cooling or at best not changing.

So the missing heat is hiding deep in the ocean. It must be hiding there because.... And then we get into circular logic. This is just one more example of warmist scientists spinning a new explanation when the earth doesn't behave as their models predicted. But don't worry the models will be right in 80 years or so. And we must act now!

What is unprecedented is the rate at which the oceans are warming now. What is even more unprecedented is that this occurring during a time when the natural variations within our climate would tend to show an over all cooling trend. Land, air and sea, aka global.

Here is what I wish for you to do, Ottawa Mike. Using the Laws of Physics, Chemistry and Thermodynamics I would like for you to show any scientific reasoning as to how our adding tons/day of CO2 into our atmosphere will not have a warming effect on our global climate above and beyond the natural variations within our global climate. Should you not be able to do this then anything that you say is based solely on unsupported conjecture.

You continuously use misdirections, misinformation and the lies of others to try to advance your ideology over what the science shows us. You do this to promote confusion among those that lack the knowledge to understand better.Your apparent strength lies in the lack of knowledge or the lack of intelligence in others. You cater to the uninformed and the ideologically driven. ... I will leave it that.

There is no forensic(proxy) evidence that would indicate that our oceans have ever warmed at their present rate in geological times, unless a major, catastrophic event occurred to cause such a warming event. I will turn it back onto you and allow you to show us any forensic evidence to the contrary.

You skipped right over the second paragraph I wrote and until you can satisfy my second paragraph then my third paragraph concerning you holds true to anyone that uses logic and has an analytical mind. It is so typical of you to point the finger back at others and accuse them of what it is that you yourself are doing. Satisfy the second paragraph or live with the third paragraph!

I knew they would find the missing heat. If you drag a billion dollars through a college campus, you never know what you might catch. (yes that was a reference to Paula Jones and Carville in case it wasn't obvious)

Some1, instead of accusing people of promoting confusion, maybe you should just look into the mirror and ask why you believe in things that aren't proved. I don't see eye to eye with Ottawa Mike on everything but the vitriol that some of you alarmists spews gets on my nerves anyway. It is a good question yet you act like he is suggesting Hale Bopp isn't coming back for you. I just don't get it.

the earth has had a good balanced climate since the continents broke apart. I remember the days when we had one big landmass and the temperatures were crazy hot and cold! I think water is a great mediator and we are losing atmosphere ever year thank god our volanoes replenish it still or we would be like Mars all our atmosphere gone just huge frozen oceans

Not sure about unprecedented, but the last 2 decades have been much warmer than the previous 3 decades http://www.realclimate.org/index.php/arc...

If we had unprecedented rise in ocean heat content, we would have to have unprecedented rise in sea level, which we do not have.

We don't have a lot of data. We need to spend billions more so that we can determine that ocean warming is UNPRECIDENTED and that it is .000000437226C warmer than the MWP.

I remember the good old days when Mann and the hockey team were in full swing. With MWP disappeared, the big news of the day was that current air surface temperatures were "unprecedented". They haven't been seen since Roman times and perhaps longer.

Well, with the pause in air surface temperatures now going on 17 years, the focus has become the ocean. The "missing heat" has been found and by gosh warming is still matched lock step with CO2.

So my question is, is current ocean heat content "unprecedented"? Is there something different (and not natural) about current ocean heat content that points to anthropogenic sources?
