How does increasing ocean heat content affect the climate?

Posted at: 2015-03-12 
You've got to be a REAL man-made Global Warming TRUE BELIEVER to believe that warm water is sinking to the bottom of the oceans, that defies the laws of physics.

But these are the same people that will try to tell you that warming causes cooling, so we are obviously not dealing with rational people. Alarmists will say ANYTHING, no matter how absurd to try and push their agenda forward.

-----------------------

I'd recommend you read the guest article at:

? ? http://www.realclimate.org/index.php/arc...

The lead author of a new report discusses may of the details you'd probably want to know about. What's nice is that scientists don't "knee jerk" when something interesting happens (such as a slight change in trends) and instead ask the important question of "why?" and then go out and try and do the work required to get a better understanding. I like that behavior a lot.

Here's a question I'd like to ask you (if you are willing to read the guest's writing at the above link.) Partway down that link there is the following text in février's introduction:

? ? ? ? "Stronger trade winds push warm surface water towards the west,

? ? ? ? and bring cold deeper waters to the surface to replace them.

? ? ? ? This raises the thermocline (boundary between warm surface water

? ? ? ? and cold deep water), and increases the amount of heat stored in

? ? ? ? the upper few hundred meters of the ocean. Indeed, this is what

? ? ? ? happens every time there is a major La Ni?a event, which is why it

? ? ? ? is globally cooler during La Ni?a years."

The first sentence says "bring cold deeper waters to the surface," the second sentence says "increases the amount of heat stored in the upper few hundred meters," and then the last concludes "why it is globally cooler during La Ni?a years." What I'd like YOU to do is to make sense of that and put it into a larger context of understanding.

In short, does the article make sense to you or do you have any specific areas of substantial disagreement? If so, what soundly reasoned scientific arguments can you bring to bear to challenge some specific conclusion you see there?

If you engage this question in your own head, I think you will have your answers.

EDIT: I don't see any contextual analysis on your part. Just some quotes. I am suggesting that if you actually engage your own question in the context of what is written there, and think about it closely enough to make sense of it, then you will have your answer. Or, at least, some points you don't understand or else disagree with. And if so, you should be able to discuss them here.

The only real possible effects are that the sea levels will rise slightly due to the fact that the warmer water is, the less dense it is. Anything else is going to be a guess. Its like all of the guesses the warmers have been making about the "climate change". They publish hundreds of papers that all predict different things. When anything happens, they go to their repository and claim they predicted it.

It should be noted, though, that the oceans are warming far more slowly than the air. This would inherently mean that the oceans will continue to serve as a heat sink and that their role as a heat sink will increase. Some people are actually claiming that the oceans will stop and start putting that heat back into the atmosphere and the rise will be even quicker. Ridiculous stupidity by warmers who have little understanding of physics.

Of course, you probably know all of this.

I don't actually know, as it's not really my field. However, I can speculate.

Most changes to ocean heat content, and especially deep ocean heat content, will not directly affect weather. But, what they will affect is ocean circulation patterns. Those patterns may, in change, affect weather. I would expect most of those changes to be on decadal (or more) time scales, since the deep ocean currents are pretty slow, though it wouldn't surprise me if changes in ocean heat content change the frequency or severity of El Nino and/or La Nina events.

When the ocean is warmer, la Nina years will be very warm. It is already happening. 2011 and 2012 were la Nina years, and yet, they were warmer than any el Nino year prior to 1998.

Global Warming ended in 2012, confirmed by our Satelite reports 11/28/2012 that ICE accumulation has returned to earth after 36 + years of Global Warming. GET USED TO IT. Mike

I guess that added heat caused increased rain in Britain and droughts in California (sarcasm).

The uncertainty associated with measuring ocean temperature and correlating that to warming from CO2 is so high that it should be mocked and ridiculed. It is laughable. Instead we have alarmists treating it like it is credible and well understood.

It must be magic. We have deep ocean warming that skips the inconvenient surface to cause all sorts of catastrophes. It is magic how oceans heat up in a period of a pause in global temperature rise. Those magical CO2 molecules have circumvented normal physics and skipped the surface interface to warm the deep ocean directly. (Again sarcasm)

the temperature of the caribean has gone up 2 degrees F in the last 20 years . it takes an increadibly large amount of energy to raise the temp of several trillion gallons of water 2 degrees . this will increase evaporation , meaning more rain and snow on the east coast .

We have very little understanding of what happens in the oceans, even our discovery of the Pacific decadal oscillation is a recent one, heat could be cycling in and out of our oceans in regular cycles, and could have

been doing for many thousands of years, but we wouldn't know that.

To make statements on what is happening, without full understanding of how our oceans work now and in the past, is just plain unscientific.

The explanation for the recent pause in warming is that there hasn't been a pause but rather heat from an energy imbalance has not been increasing the surface air temperature but rather has been increasing ocean heat content. Trenberth's work in this area is usually what is quoted along with cooling in the Pacific. For example:

"We also have to learn more about what the very deep ocean is doing – we know heat is going there." http://www.theguardian.com/environment/climate-consensus-97-per-cent/2014/feb/20/accounting-for-global-warming-oceans?CMP=twt_gu

So my question is basic. How is deep ocean heat content affecting current weather like the UK's recent rainfall and flooding?

Also, when the IPCC released its SREX report on extreme weather, were the changes to extreme weather based on surface air temperatures or deep ocean heat content?
