Klapper at 02:27 AM on 16 May 2015Models are unreliable
@Klapper 908:
In addition to the atmospheric component of global heat changes, I've worked up a graph showing the ice melt component. Arctic sea ice is from PIOMAS data, Greenland and Antarctica are from GRACE data and before that some "generic" estimates of ice mass loss for these 2 continental sheets. Antarctic ice melt is my own model based on average thickness and the delta in ice area. Crude but as you can see, either way ice melt is not a big component of the global heat flux equation.
Compare this with Hansen et al 2011 Figure 12. Ice melt is a very small contribution to the global TOA energy imbalance and recent increases in ice sheet melt are to a degree cancelled out by recent increases in global sea ice. Note I am using the same method as Hansen, a rolling 6 year trend to calculate ice mass changes, and thereby heat fluxs on a global TOA basis.

Referring to the article on the Larsen-C ice-shelf it says:
An ice shelf forms when a glacier on land reaches the coast and flows into the ocean. If the ocean is cold enough, the ice doesn't melt. Instead, it forms a permanently floating sheet of ice.
What temperatures are we saying makes it too cold for an ice-shelf to melt? By contrast what temperatures are we saying makes it start to melt and how difficult a question is this to actually answer?

I think it is more than worth reminding ourselves what 'economics' means so, yes, considering exactly these types of points of view. There is an idea called Jevons Pardox which I think is what you talking about and more specifically how there must be a point of diminishing returns,... and a tipping point at that if I may!

Spot on uncletimrob, it is very similar to how Bloom's Taxonomy works. Perhaps I should have emphasised an 'inclusive hierarchy'. Essentially, it just provides deniers with more avenues of excuses and in a way they use it to try and cloak themselves in some scientific respectability (when it suits them).

What Lindzen says scientifically, (ie in peer-reviewed journals) is not a problem and is addressed there. Addressing what Lindzen says when talking to the naive (eg congress) is the problem. I wonder how many of the statement list here would have been made if addressing an audience of his peers?

Attaching derogatory labels to opponents of your argument does not promote better understanding in non scientist. It allows your opponents to to stereotype you and then dismiss the worth of anything you say. This in turn polarises the argument to its extremes and eventually leads to a megaphone debate. In a scientific debate, it is the sober, well argued, revealation of scientific information, without resorting to stereotyping of opponents that will ultimately win through, i.e. the information will always trump the stereotype. Also, to convince genuinely skeptical people, rather than the so called climate denier/skeptic/obstructionists, you need good metaphors easily understood by non-scientists, to convince people. In other words SMILE, simple makes it lots easier, is better.
While Sks presents the scientific arguments, sometimes, the complexity of the scientific debate does not make the science easily accessible to the non-scientist. This leaves a chasm for opponents to AGW and CC to use dismissive stereotypes to drive through their scientific misinformation and political rhetoric. The CO2 problem for the Earth is similar to a swimming pool whose chlorine pump is broken. Even though the quantities are small, if too much chlorine accumulates, you will get burnt; if there is too little, you will get algae. In both cases you won't be able to swim in the pool. Other metaphors, like intravenous administration of a drug, again, only trace quantities are used, but too much you will die, too little you will get sicker and may die. The same goes for a fertilizer/farming metaphor. To much you can't grow anything, too little you get weeds. The minute increase trace argument, can be likened to interest rates on an investment account, and the climate models are unreliable argument, might be better counteracted by wondering why they rely on economic models to make their investements which is surely as complex, and not always accurate. There are plenty of simple metaphors to describe the CO2 problem before explaining the scientific complexity of the carbon cycle where the recent rise in CO2 is put into its proper geological context.
To question a scientist as eminent as say Richard Lindzen, there is no need to resort to a label. You can use what he presents scientifically. As I understand it, he predicts that doubling CO2 will only yield a 0.5 degree C increase in temperature, hence of no consequence. However, over the last century we have already seen a 0.8 degree C increase in temperature, while CO2 levels have increased by 40%, hardly a doubling. Without any other scientifically verifiable casuality, I would have thought that this would be enough to negate his key argument, that doubling CO2 is not significant. There is no need to use labels like denier. Leave the labels like warmist, carbonite, leftie, greenie etc. to those whose scientific arguments are so weak that they have to resort to them. Also, I would have thought that the 15 degree difference in the average global temperatures between the Earth, with its 200-300 ppm CO2 (today 400 ppm), and the Moon (zero CO2), and with the paleoclimate evidence, would be enough to address the climate sensitivity issue in the mind of non scientists. Presenting simple scientific inconsistencies in the argument of opponents by using simple metaphors is more likely to promote better understanding than resorting to yet another label.

@ 1 TomR, Both the Tory win and the battery hope are bad news. The good news is that if we look outside the box that we choose to think in, a solution is still possible for another 100 years or so. Political victory will go increasingly to the anti-climate control side, forever. One could extrapolate species self-extinction from this. People want more cars and junk, and they will do anything to get it. Self-delusion is no problem as we all know. As far as batteries? That’s a weak solution, the assumption is that renewable energy can then power our car cityscapes: 1) Pollution in creating the infrastructure, 2) expansion of demand to meet supply from car cityscape concept. 3) growing world wealth.
The good news is that at 20% of land, deserts represent about 100 million km2. Since they currently only hold less than 2 kg biological Carbon ( C ) per square meter. If these were forested C content could increase to 10 or even much higher, depending on water regimen. A little arithmetic tells us we could accommodate 160 GT into 20% of deserts. If we make them really rich forest, or sequester the biomass into the soil systematically, we can double that to 320 GT, then double the amount of desert we can take out 640 GT. That's greater than the current C budget for 2 degrees right?
The problem is our imagination is nailed down to old ideas, and new ideas must fit inside those old ideas. However, a good carbon-tax could free up our imagination through market mechanisms.

SkepticalRaptor at 06:21 AM on 15 May 2015Ask Me Anything about Climate Science Denial
"Scientific consensus" has a distinct meaning in science. It is not a debate, it is solely dependent upon the quantity and quality of evidence published in high level peer-reviewed journals. As I've written before, it is not a debate, it is not an argument. It is only one thing, it is collective agreement by the scientific experts on a particular scientific issue. It is absolutely based on evidence, and evidence alone.
Like "scientific theory", "scientific consensus" has been polluted by the the more common, and less scientific, definitions of these words. In science, a theory is essentially a fact, and a fact that can be predictive. The scientific consensus is not based on a debate amongst 10 scientists in a room. It is not some form of democratic voting. It is just a weighing of the quality and quantity of evidence.
Scientific consensus is what eventually forms a scientific theory, which is predictive in power. Anthropogenic climate change has already achieved a consensus.
The scientific consensus is solid about anthropogenic climate change. If someone wants to refute that, they need to bring real scientific data in the volume and quality that supports the consensus, not logical fallacies or conspiracy theories. -
Ronsch at 05:39 AM on 15 May 2015Ice loss in west Antarctica is speeding up
I'd like to point out that 100 years ago Einstein showed that gravity doesn't attract but rather distorts space which causes objects to move towards each other. Therefore you cannot say "The huge ice sheet has such a large mass that it attracts objects toward it", but rather that it distorts space around it and thus moving the satellite towards it.

It strikes me that people who used to call themselves "skeptics" now often call themselves "lukewarmers". Anthony Watts and many others come to mind. Lundzen in 1989 said that warming would not exceed the noise in the data. Hansen was correct in predicting warming. The "skeptic" brand has been shown to be incorrect. They are trying to continue their stalling by putting on a new hat. How long will it take the mainstream media to see through the new outfit?

Nick Palmer at 23:33 PM on 14 May 2015Lukewarmers – the third stage of climate denial, gambling on snake eyes
I have long suspected that the most voluble deniers, such as Morano, Inhofe, Monckton etc continue to use arguments that they surely know have been debunked for one reason. That is that those sound bite factoids and arguments work very well to sway the minds of the general public, in op-eds, lectures, articles or debates.
Why wouild they want to do that? I think that behind all the out and out antiscience they spout, these people have been secretly convinced by the lukewarmers, such as Lindzen and Spencer, that the ultimate results of us continuing to use fossil fuels won't be very much at all - benefits may balance harm and we'll have enough time to adapt to any harm.
The loudest deniers, I am speculating, are doing it, even though they don't believe it, because inwardly they have been convinced that we don't need to do much, if anything. However, as political animals, they know that selling the public that is a weak flawed message. FUD works better to achieve their ends.
If they told the public that a few scientists claim that the sensitivity is lowe enough that w wouldn't need to bother, they know that the public would then look at Dana's analogy of throwing dice and weigh up the risks of believing the lukewarmers or everybody else. I think most ordinary people are sensible enough to judge what to do. They look both ways when crossing the road, they don't buy outdated food. They wouldn't risk their climate on a minority scientific view.
I have come round to the belief that the danger of trusting in the lukewarmer position is the greatest problem we have. I think science and science communicators need to get that message out far bettre than has been the case previously -

@6, There was a famous interview/commerical-I-suppose on Youtube a number of years ago(not sure how many) where Dr David Mills was saying there is now no way we can stay under 440ppm....so the information being floated around does seem a little contradictory and the denial brigade can almost be forgiven for driving mack trucks through what seem like gaping holes of information. Yes, it all depends where you go for information of course.
My point was that I'm guessing a lot more than 440ppm is locked in- I'm not sure how This David Mills character came up with his numbers so I am of course merely guessing/being potentially paranoid... the IPCC reports are known to be conservative by nature for instance and there was an article just recently on Sterling Engines being tested in South Africa over the last 4 years... combining this with the new phenomenons of formula-e racing and possibly Virgin competing with Tesla for the electric car market and Tesla itself saying it may just go into producing batteries the world does seem to be displaying something of a turn !
(I could find that video but it may take some searching... the only relevant information was that he though 440ppm was locked in and they didn't know if it was possible to go over the limit and then come back down under at that time but that it would be impossible to not break it in the initial sense!)

uncletimrob at 16:58 PM on 14 May 2015Lukewarmers – the third stage of climate denial, gambling on snake eyes
@Neo. I believe that it is hierarchical in the same way that a person can be "situated" in one step of Bloom's Taxonomy for say Maths but in another lower or higher step for another subject, say English. My experience as a teacher suggests that even within one subject a student can move from one step to another depending on the topic.
So, I'd suugest that the people you describe are moving between steps of the denier hierarchy, perhaps depending on their level of understanding of each area of discussion/dispute.
-
Neo at 14:27 PM on 14 May 2015Lukewarmers – the third stage of climate denial, gambling on snake eyes
A very informative scale for climate change denial. However, would you describe it as a hierarchical because I notice deniers I converse with will tend to regress or default to lower levels depending upon the topic or even via their desperation. For example, they might admit to warming in relation to evidence of temperature rises but another time will say the planet has parts that are not warming or that these balance out the warming. It would be interesting to do a longitudinal study of deniers over time to see how their denial progresses and with what frequency they might regress.

Rob Honeycutt at 13:58 PM on 14 May 2015It's not urgent
Oh, and regarding "point of no return..." "Point of no return" would likely not be a term anyone would use since it leaves too many loose ends.
We are currently at about 0.8C over preindustrial global temperature, and with thermal inertia we've banked about 1.2C of temperature rise no matter what we do.
That, in and of itself, means there are going to be aspects of climate change that we can't stop and will have to adapt to. After we pass 2C over preindustrial temps we risk passing tipping points where we don't know how much additional warming will result. Researchers are urging us not to pass that 2C limit. At around 0.2C/decade... meh, we have a little bit of time, but we desperately need to be enacting policies now that can keep us below that 2C limit.

bozzza, Re the data you reference regarding 2D ice extent increases in Antarctica, the 3D ice mass budget studies indicate large accelarations in the rate of 3D ice loss (mass not 2D measurment).
See the article SOTC: Ice Sheets, which refernces these studies (Rignot et al. 2008).
The 2D ice extent in the Arctic (north pole) indicates a downward trend.

Just to note that this article relates to 'normal' volcanic eruptions. Regular visitors to this site will recall there have been several articles on Large Igneous Provinces that have occurred rarely in Earth's past, were colossal, and which generated dire environmental consequences including global warming. Some article links: here and here and here.
LIPs are an altogether different phenomenon than normal volcanic eruptions.
There have also been Supervolcano eruptions much larger than 'normal' volcanic eruptions (but much smaller than LIPs) as summarised by the USGS here.
I put together this handy dandy graphic so people can get an idea of the relative scale of these things. The area of each circle represents the volume of lava erupted.

The average so far this year has been +0.79°C (record!), and the last 12 months +0.73°C (also record!).
Most forecasts predict a strengthening of the ongoing El Niño, so 2015 will almost certainly become the first year warmer than +0.7°C, and maybe even warmer than +0.8°C. The following months will be very interesting!

MA Rodger at 22:47 PM on 13 May 2015Climate's changed before
skeptic1223's over-enthusiasm for linking present-day CO2 levels to some threashold CO2 level which allowed the era of ice-ages to kick off appears to have run its course. Yet he did present one aspect of climate that seldom gets discussed.
skeptic1223 began his input way up @420 with the observation that orbital forcing had become a bigger feature of climate since the inception of the Arctic glaciation by creating higher ampitude oscillations in the global temperature record. The graphic below (derived from Lisiecki & Raymo (2005) Fig 4) was presented @423 by way of illustration.
Such apparent increases in ampitude do support the idea of an increase in climate sensitivity in some manner as in the long run orbital forcing cycles are constant in size. Such forcing is large at specific latitudes while small globally. To suggest this increased ampitude (and thus increased sensitivity) is somehow a function of CO2 levels is of course wrong. But it does beg the question - why doesn't this increased ampitude in oscillation make ECS vary with temperature/Arctic glaciation?
My view of this is that to calculate the sensitivity of climate to orbital forcing from what appears a hysteresis loop could be used to show big sensitivity changes but these would not be very helpful for our purpose of finding ECS under AGW. Thus the slow feedbacks of albedo, CO2, methane, etc. are considered as forcings rather than feedbacks to allow a meaningful ECS to be calculated.
The reference cited by AR5 in this matter is PALAEOSENS Project Members (2012) which states:-"Astronomical (orbital) forcing is a key driver of climate change. In global annual mean calculations of radiative change, astronomical forcing is very small and often ignored. Although this obscures its importance, mainly concerning seasonal changes in the spatial distribution of insolation over the planet, we propose that the contribution of the astronomical forcing to (the climate forcing) may be neglected initially. When other components of the system respond to the seasonal aspects of forcing, such as Quaternary ice-sheet variations, these may be accounted for as forcings themselves."
This accounting of slow feedbacks as forcings is a reason for ECS only accounting for fast feedbacks.

CBDunkerson @5,
in another year or so we'll hit 400 ppm as the annual average
Note the trend column in the monthly data, which just topped 399 in March. So, at current rate of over 2ppm/y, the trend will hit 400 in jsut 5-6months, very likely sooner than in a year.
As for your FF future assessment, unfortunately, there are big areas where FF cannot be replaced by renewables yet, e.g. transport, esp. aviation. That's why oil and gas still have future beyond your decadal limit. I agree with you with respect to coal: it's use as the source of energy should've already been superceded by cheper and cleaner renewables, political will being the biggest barrier at the moment.

Tom Curtis at 22:16 PM on 12 May 2015Climate's changed before
skeptic123 @463, looking at the Vostock data another way, I examined in detail each of the four transitions from inter-glacial to glacial in the Vostock data. From each such transition, I determined the minimum interval for the transition, calculated as the time from the most recent relevant datapoint above -2 C to the time of the first datapoint following which was below -4 C. The relevant intervals were, from oldest to newest:
3426 years (average rate of decline = -0.006 C per decade)
4399 years (average rate of decline = -0.005 C per decade)
2654 years (average rate of decline = - 0.008 C per decade)
2028 years (average rate of decline = -0.01 C per decade)
(Note: the rates of decline are for a regional temperature value. Global values would be about half that.)
No matter how many times you repeat the quote, the data does not support it. Further, science proceeds by evidence, not by out of context quotation (which is rather the mark of pseudoscience).
Now, it is possible that the scientists who made that claim define an "ice age" as any period with a temperature anomaly less than x, where x is -0.5, or -0.1, or some other arbitrary value. It is also possible that they consider temperatures of x + 0.5 C as "a warm climate". In that case, what they say is true, trivial, and so vague without the specification that that is how they interpret their words, and a specification of x as to be useless. If you want to use the quote, it is therefore incumbent on you to find out the exact interpretation the authors give to the words.
Absent that effort, however, it remains that the data directly contradicts the claim supposedly based upon it. So, if you are not prepared to make the effort to provide the context of the quote on whose authority you rest, it is incumbent on you to follow the data. Failure to do so simply demonstrates that you accept data only if you think it supports your position. Worse, it shows that you present data that in fact falsifies your position as supporting it, and refuse to acknowledge the detailed examination that shows that the data refutes your position. Again, those are the hallmarks of pseudoscience.
Long experience has shown that debating with pseudoscientists is completely unprofitable in that their positions are not based on reason and evidence, and therefore cannot be altered by either reason or evidence. I also think that the complete divorce of your opinions from actual data is sufficiently evident to any interested readers that I do not need to spell it out again. Consequently I will ignore your responses in future until such time that you start correcting your position based in the actual data.

Rolf - oxygen makes up about 21% of Earth's atmosphere and CO2 about 0.039%. Furthermore, we know life has flourished prior to the addition of fossil fuel CO2 to the atmosphere by humans so, if we could bring back to a pre-industrial level, there would be ample oxygen available for plant and animal life.
There's no need to worry about CCS other than that it is so far as useful as the tooth fairy and unicorns.

@ Will. It will be interesting to see how "natural variabilty" (eg El Nino) is viewed in western Queensland which is already suffering a drought. My - admittedly limited with some friends who live in Roma - experience is that their political leanings prevent any discussion that the climate is changing and that these extended droughts may become the norm. I certainly feel their pain as their livelyhoods are destroyed, but dissociating politics from science is a hard one in a tough, unforgiving (climate wise) region.

BoM just called it: "the Bureau's ENSO Tracker has been raised to El Niño status"
