lawrocket 3 #454 February 15, 2014 brenthutch If you can not predict the pause you can not explain the cause. Apparently "climate scientists" have just discovered the pacific decadal oscillation. Kallend says there is no pause. The heat is in the ocean. In deeper layers. I took a look. While there isn't data for deep ocean, there is some actually observational data to support this. The ARGO page shows that since the 1960s, the warming of that layer was 0.06 °C. [Url]http://www.argo.ucsd.edu/global_change_analysis.html[/url] Now the big issues are: (1) How is 0.06C change in sea temperature at shallow-to-midlevel ocean depth a problem? I.e., how is that additional heat going to get into the atmosphere and change the climate we live in? (2) It does make some sense (2nd law of thermodynamics) that heat moves to the deep ocean. This law would seemingly be violated by having 1.06 degree C water transfer heat to 3 degree C water up above. (3) Is mother nature foiling the grand plans of the Koch brothers, oil industry and the Republican by sequestering heat into the deep oceans where it doesn't do any harm? (4) Since the density of water increases from 0 degrees C to 4 degrees C (yes, kallend, I paid attention to your lesson on density) might deep ocean heating be caausing thermal contraction at the coldest deep ocean spots, thus resulting in a balancing out of thermal expansion at upper levels? All these questions. Assuming deep ocean sequester is true, it looks like it may be the answer to the problems. My wife is hotter than your wife.

The deep ocean takes the heat and keeps it. Question: what sort of chaos can you see being caused by the .06C temperature increase? Because I can't see much. I can see a scenario where small temperature changes could have a catastrophic effect. Large deposits of methane hydrates exist in the ocean at depths down to ~3,000m. Methane hydrate is a clathrate of water and methane, with the methane trapped in a lattice of water. This structure is very sensitive to pressure and temperature (see the stability curve here, just scroll down a bit). Warming of the deep ocean could easily "melt" these clathrates, starting with the ones at shallower depths, resulting in release of large amount of methane. Methane will displace oxygen from water, resulting in anoxic oceans with obvious bad consequences for any marine organisms that need oxygen. Methane will be released to the atmosphere, and as methane is a much more powerful greenhouse gas than C02 is, temperatures will rise, warming the deep ocean even more and resulting in release of even more methane in a positive feedback loop that might continue until all the methane currently locked in methane hydrate is released. There is pretty good evidence that release of methane in this manner contributed to the mass extinction event at the end of the Permian, which resulted in the extinction of >95% of all marine species, and >80% of terrestrial life forms. That event was most likely started by release of large amounts of C02 due to a supervolcano erupting through massive coal deposits in the Siberian Trapps. The effect of the C02 was magnified by the release of additional methane. The oceans became anoxic, and were dominated by sulfur-fixing bacteria, the kind that forms that black stinky scum in stagnant water. On land, not only were temperatures scorchingly hot, oxygen partial pressures fell to levels currently found ~15,000 feet (where we need to provide supplemental oxygen on planes). What concerns me is that we do not know where the threshold is to start this process. Methane hydrate stability is affected by pressure (=water depth) and temperature. Shallower deposits will release methane gas with less heating than deeper deposits, so there is no one water temperature we can confidently point to and say nothing will happen as long as we don't cross this line. Once the process starts, the huge heat capacity of the ocean will ensure that there will be no way to reverse the process. I think many people (I suspect including you, Jerry) make the mistake of thinking the effect of temperature on climate will always be linear, so incremental increases in temperature will only produce incremental changes in climate. The history of past climates suggests otherwise; non-linear processes (such as melting of methane hydrates) can produce radical changes in climate triggered by relatively small changes in temperature. Climate sensitivity to perturbation has (over geological time) been influenced by factors such as distribution of land masses; clumping of tectonic plates into supercontinents such as Pangea or Gondwana, or presence of land at the poles (as we have today) is associated with less stable climates. The speed of change is also important, as that will influence potentially stabilizing forces. For example, slow warming of the deep ocean could allow methane released from shallow hydrates to be trapped in new methane hydrates forming at deeper depths, with little net release. Fast warming could dump methane into the water/atmosphere faster than it can be redistributed to deeper deposits or consumed by methane-fixing bacteria. I think we are playing with a system we do not understand, but one that past history has shown to be capable of rapid jumps from one state to another as opposed to slow gradual change. I think that is very unwise. Don_____________________________________ Tolerance is the cost we must pay for our adventure in liberty.

lawrocket 3 #467 February 16, 2014 Excellent post. I'll hit some points of discussion. (1) Hydrates have been discussed for a long time here. I agree there is a potential for trouble. I think we can test in a lab the various pressure depths and temperatures that would cause phase transition. But, like CO2, we probably cannot account for all of nature's variables. But it can certainy lead to a positive feedback loop. I also note that shallower depths provide a bigger issue, not just because they are easier to heat but shallower depth doesn't allow much space for CH4 to dissolve. (And having gone to college within breathing distance of Coal Oil Point, I can tell you that methane clouds blowing by provide a distinctly unpleasant smell.) There are other feedbacks that worry me more. The main one being water vapor. Ocean surface is easier to heat. It heats. Evaporates ito atmosphere. Causes more ocean heating, which evaporates more into atmosphere. Etc. I don't know why this one isn't mentioned. That's how a runaway greenhouse effect occurs. (2) "I think many people (I suspect including you, Jerry) make the mistake of thinking the effect of temperature on climate will always be linear, so incremental increases in temperature will only produce incremental changes in climate." Actually, it's the deniers who are saying that climate has never been stable or smooth. Deniers have always said that natural variations are huge! And that even slight differences that we see in nature have had tremendous consequences and will continue. It's the alarmist side that says that extreme events aren't natural. Check out billvon's history of insisting that we've never seen chanhes come this quickly. According to you (and I agree with you) we sure as hell have. I have never thought climate change would be smooth. I have merely said that 2100 will not be fire and brimstone. I have over the past several years maintained that climate change is real, humans are A cause of it, but that the effects will be mild and well within our ability to adapt and cope. Climate historically makes HUGE changes in short times. Whole spruce forests changed to pine forests in 50 years in the Northeast US 10k years ago. A whole archipelago called New York City was created by climate change. And rather suddenly. The AGW narrative requires that sudden changes and events be forgotten which enables attribution of every drought or flood to climate change. That is my problem: deniers APPRECIATE the sudden changes that can occur, are occurring, and will occur and that the earth is never "in balance." Versus the consensus narrative that WEATHER is stable and unchanging except for mild over the course of thousands of years until humans stepped in. A new ice age can occur with a drop of 4 or 5 degrees C. I know that. Because it's happened so many times. (3) "Climate sensitivity to perturbation has (over geological time) been influenced by factors such as distribution of land masses; clumping of tectonic plates into supercontinents such as Pangea or Gondwana, or presence of land at the poles (as we have today) is associated with less stable climates. " Of course. When we had Pangea, can you imagine what hurricanes must have been like? All these things influence climate, and geography probably has the greatest effect on the ocean. But the biiggest cliamte sensitivity we're discussing is climate sensitivity to CO2. We don't know what that sensitivity is. The IPCC estimates between 2 and 5 degrees C for a doubling of CO2 concentration. I allege that the past couple of decades suggests a sensitivity of probably under 1 degree C. Yes, this can mean a lot. It can also mean relatively little. The ENSO gives temperature changes greater than that, meaning that such a change is within the realm of natural variability should I be correct. One thing is pretty certain - it won't be until at least 2050 before we have any idea what the deep ocean temperatures are doing. (4) "I think we are playing with a system we do not understand, but one that past history has shown to be capable of rapid jumps from one state to another as opposed to slow gradual change. I think that is very unwise." You had just finished mentioning "speed of change." And have confirmed that the climate can and does change quickly with or without us. This is nature. And we, as people, have done a good job of adapting to this changing climate. And even adapting the climate. We know of places where hydrates are found. The Deepwater Horizon disaster put clathrates into the collective conscience. That was 2000 meters deep in the Gulf of Mexico (a pretty highly regarded warm water body that powers lots of hurricanes). Much of this was likely gaseous CH4 which formed into a hydrate when mixed with water. It was pretty much flash hydrate synthesis - so quick at that depth that it iced over mitigation technologies and rendered them useless. Rather than dealing with hydrate ablation, it was accreting too rapidly to work around it. I tend to view evidence like this as an indication that hydrate gassification is not an immediate risk at depths that are less than the average ocean depth (greater than 4200 meters) and average ocean temperature (3.9 degrees C). From a climate standpoint, sea surface temperature is what we should be worried most about. But some great points, Don. There is a lot we don't understand.

rushmc 18 #472 February 17, 2014 this is interesting to read Obama claims that CA's drought is being causes by AWG When the science has no clear link My point is more to what you say about the alarmists losing credibility by doing this http://www.nytimes.com/2014/02/17/science/some-scientists-disagree-with-presidents-linking-drought-to-warming.html From the link QuoteIn fact, the most recent computer projections suggest that as the world warms, California should get wetter, not drier, in the winter, when the state gets the bulk of its precipitation. That has prompted some of the leading experts to suggest that climate change most likely had little role in causing the drought. “I’m pretty sure the severity of this thing is due to natural variability,” said Richard Seager, a climate scientist who studies water issues at the Lamont-Doherty Earth Observatory of Columbia University.

lawrocket 3 #473 February 17, 2014 I took my kids out to see Marine One and Air Force One on Friday. I'm well aware of what the President said. He said that the drought is just climate change. And that farmers need to learn to conserve (mind you, farmers pretty much invented water conservation since it costs them less to use them less) and basically that the Pacific ocean needs the water more than farmers. But here's a $150 million for you for the unemployed workers. Please check out the climate hubs. It certainly has rankled some. No proposed solution, but a handout. Welfare instead of water. My opinion? Water conservation also includes storage. Conserving means using less and saving. Problem is that a nice juicy peach can't be nice and juicy without water. The farmers aren't the end users - the consumers are. A good El Nino would be nice for us. We haven't had one since 1998. Or any El Nino in five years. My wife is hotter than your wife.
