Very sad to hear, chriskoz,but sadly no surprise.
This is not a rhetorical question... Do you think many people seriously believed that TA's direct action was meant to achieve anything?
I see the right-wing media and a few TA fans playing along with the charade, but I always imagine they know better deep down. After all, TA got into power on a denialist wave, within his own party, around the time of 'Climategate', and he knows that is where his fanbase still is.
I see scientists and environmental groups declaring Direct Action to be a doomed strategy of paying the polluters to achieve very little. Most Liberal voters could not care less about the scientific details, or they woudln't have let an antiscience prime minister come into power in the first place.
Are there really people who actively argue with conviction that this is a good idea and that it is going to have a useful effect (on a per capita basis) on global warming? I see it more as a foil with which they can deflect criticisms from the left, as in: "Global warming is rubbish, and even if it turned out to be real, we're doing our bit anyway, so stop complaining.. "
Moderator Response:[AS] For the benefit of non-Australian readers, "TA" is Tony Abbott, the Australian Prime Minister (I assume).

The last sentence by Luther to Michelle "he's crazy" creates an ambience of joke around Obama rant about "stupid irresponsible snowball throwing...". Obama must have orchestrated it to soften the ensuing conflict with Sen. Inhofe and that's understandable.
But the issue is not a joke (at least for me), therefore Obama should have left the rant without adding any "craziness" to it.

More on the Carbon Reduction Auctions in Australia. Energy Regulator said the contracts were awarded to 43 contractors covering 144 projects.
“The majority applied under sequestration methods, and landfill and alternative waste treatment methods.”
I was scratching my head thinking: what sequestration methods, CCS yet to be developped? But govs have explained the detail:
A$660 million of contracts to deliver more than 47 million metric tons of abatement. It paid an average A$13.95 per ton to companies for projects including capturing methane from pig manure, planting trees and managing fires in savanna grasslands.
Well, now I understand: my "Carbon Reduction" tax dollars went to the projects that have little (if anything) to do with FF emission reduction. Managing fires have nothing to do with reduction of FF emissions. Those fires consume carbon that's mostly couple decades old (forrest understory) or at most couple 100s y old (if some old trees are burned), while 300-400m y old coal burning continues unabated. No wonder, because coal is "good for humanity". Or pigs' emission sequestrations... Well, our govs are trying to get away with that travesty which amounts for deliberate misleading of taxpayers who don't understand the difference between the fossil fuel emissions (where the money is supposed to go) and pigs' emissions (where the money is going) which as a mitigation effort is just a joke IMO. Someone hopefully will pick it up and duly explain to the australian public, whose money is being wasted.

Philip Shehan at 20:45 PM on 3 May 2015The climate 'hiatus' doesn’t take the heat off global warming
England's paper has (predictably ) been portrayed on Andrew Bolt's blog as a backdown requirng an apology
"Warmists who denied the pause now claim to explain it"
While I understand that the paper is a useful in explaining what the consequences are if there is indeed a pause, that is a long way from being established.
Gistemp data since 2000 from the Skeptical Science trend callculator::
Trend: 0.09 ±0.13 °C/decade
For “two decades” it is
Trend: 0.12 ±0.09 °C/decade
So there is a warming trend, with a headline value lower than that for the statistically significant warming trend from 1979:
Trend: 0.16 ±0.04 °C/decade
But the error margins for the period since 2000 mean that for the short period there is a 95% chance that the trend is as much as warming 0.22 °C/decade or a cooling trend of as much as -0.04 °C/decade.
In fact both the shorter periods support the null hypothesis.
That is, they are statistically not distinguishable from the warming trend beginning in 1979.

You write "I'm not a biblical scholar, but I don't recall seeing any estimates of error margins in that book..."
My understanding of Leviticus is that it is entirely about defining error and what happens when any such error occurs. Within an approach to error such as laid out in Leviticus, the concept of there being 'error margins' disappears within a binary reality: either there is error or there is not error :-) -

There is plenty of advice on where you can up-load images that is easily found on-line, for instance here. Many require nothing more than an e-mail, a user name & a password. For instance (and I mention it as an exemplar rather than recommend it) this website allowed me to upload an image in less that a minute. I would have displayed the resulting image in-thread but the image to hand that I up-loaded is political in nature.

Peter Lloyd at 05:34 AM on 3 May 2015Overlooked evidence - global warming may proceed faster than expected
It is good to raise this issue of single study syndrome because far too many grand conclusions are drawn from just one new piece of evidence or from yet one more model.
It also highlights the point that there is no clear conclusion of the individual, let alone cumulative, effects of both negative and positive feedback mechanisms and how they offset each other.
It's also good to see a recognition of how the impact of clouds is so poorly undertood and yet potentially significant
It can't be said too often that new pieces of work that authors and commentators may exaggerate the significance of for obvious reasons, are frequently challenged by later pieces of work but that challenge is not always examined and recorded.
Keep on being sceptical might be a good mantra

Feel free Tristan. Rob, vaccines are mentioned at length in the OP. Although it has to do more specifically with the false link to autism, and it is given as an illustration for the ideas developped in the post, I'm not sure it's fair to expect the thread to be free of comments about a significant aspect of the OP. I will nonetheless respect your request, despite my intention of further investigating the claim that measles dropped to insignificance because of sanitation, a claim of which I am highly skeptical.

Really? Why should I do your work?
In 1966, the year I was born, a massive campaign of containment and eradication was launched in Central and West Africa against smallpox. In 4 years, the disease was essentially eradicated, before there was any chance to improve infrastructure and sanitation in any significant way. Eradicated in 4 years. One does not realize what a feat that was in these spoiled, worry free days of the 21st century. As of the mid-2000s, the WHO determined that the Republic of the Congo (Congo-Brazza) still had only 0-25% of its population using improved sanitation, yet the disease was eradicated there as well as in other countries part of the campaign. Other countries aren't that much better on the sanitation side, 40 years after the campaign. Some other countries, such as Gabon, have a rather small population, which makes access to sanitation easier.
I still bear on my shoulder the mark of the smallpox vaccine received in Brazzaville in the early 70s. I'm proud of it. In the former Zaire, smallpox eradication took all but 41 months, despite tremendous challenges in infrastructure and, you guessed it, sanitation. By an ironic and cruel reversal of circumstances, polio, eradicated as well as smallpox, is now on the rise in RDC because of imported cases. Perhaps some of the westerner fruitcakes who don't "believe" in vaccinations, who knows?
http://www.who.int/water_sanitation_health/monitoring/africasan.pdf
http://www.ncbi.nlm.nih.gov/pubmed/22188930
Interestingly, in the Congo Brazza, smallpox vaccination conferred also some immunity to monkey pox, which is now on the rise because of the end of massive immunization campaigns. The risk of developing the disease is 5 times greater for non immunized subjects:
http://www.pnas.org/content/107/37/16262.full
I'm done wasting my time with you, it is obvious that you are clueless, if you were not, you would already about all this. The sincerity you claim obviously does not apply to pet theories of yours. What we really need in this world is a vaccine against Dunning-Kruger.

Straight Talkin at 14:56 PM on 2 May 2015Inoculating against science denial
Just to expand a bit. Some years ago I was in almost convinced by the climate contrarians that we weren't causing the problem. Then I found skeptical science and it systematically demolished the climate deniers arguments. So I understand that arguments can sound convincing even when they are not really based on a whole picture scientific analysis. I always seek to get to the bottom line. I am not a conspiracy theorist, nor am I naive enough to not think that vested intersts do sometimes win out in corrupting situations, and have the capacity to have a corrupting influence on the scientific community and society generally. As the old quote goes 'Eternal vigilance is the price of freedom'

Straight Talkin at 14:39 PM on 2 May 2015Inoculating against science denial
Philippe Chantreau, You misunterstood my point about scurvy. I know that nutrition i.e. Vitamin C erradicated deaths from scurvy. The point I was makling is that long before vaccinations for measles were introduced the reductions of deaths from measles tracked perfectly with the reductions in deaths from scurvy as nutrition improved, to the point of insignificance.
My point regarding consensus is that although it is always worth taking into account, it should never be placed on a holy pedastal.
Could you direct me to research that demonstrates you statement 'It is interesting to note that diseases that lend themselves to immunization regress enormously in these countries when people are immunized, even in the absence of significant progress in sanitation.' ?
I am always willing to change my viewpoint based on new and convincing information. -
PhilippeChantreau at 14:23 PM on 2 May 2015Inoculating against science denial
Well I guess, since this is hinted at in the OP, it is on topic. It is interesting to see how Straightalkin formed an opinion about Measles by linking with scurvy when the 2 diseases have totally different pathophysiologies, and can truly not be comapared.

PluviAL at 14:16 PM on 2 May 2015Overlooked evidence - global warming may proceed faster than expected
This is great, evidence is clearer each day, and denyers one less rock to hide under.
But I have a question: Suppose there is a way to precipitate out an Amazon's flow from the air continuously. This means that the latent heat would concetrate higher in the atmosphere where it radiates into space faster with the 4th power of temperture K.
Would this not reduce the problem? We still have the CO2 in the atmosphere, but we systematically reduce vapor content. Does this reduce the feedback from clouds? Or does it not help because then we have less short wave radiation reflected by less cloud cover, but still have CO2 reflection of low wave radiation?
I was under the impression that low level clouds reflect more short wave solar energy, but higher level clouds refelct more long wave heat back to earth. That issue seems to be ingnored in this paper.
-
PhilippeChantreau at 14:16 PM on 2 May 2015Inoculating against science denial
Straight talkin, you're not being any more convincing. No amount of sanitation can save one from scurvy, only vitamin C from fresh fruit and vegetables will do that. You could at least bother to do a minimum amount of research on the disease you pick as a comparison. It is as if you don't know anything at all about the subject
About the consensus: nobody at SkS attempts to convince anyone to "believe" in climate science findings because 97% of relevant scientists do too. Deniers are touting the false idea that there is significant disagreement in the scientific community about climate change while, in fact, there isn't. That is what the consensus is about. The consensus exists because there is a consensus in the results of the research, just like there is, as a consequence, in the opinions of the researchers.
The scientific evidence about immunizations is every bit as compelling as it is about climate, and that is why there is also a consensus among relevant scientists about the benefits of immunizations. You cited countries where "sanitation" is lacking. It is interesting to note that diseases that lend themselves to immunization regress enormously in these countries when people are immunized, even in the absence of significant progress in sanitation. I expect now that this is off-topic enough that moderation is going to have no more patience for it and signal to us that rants about immunizations are off-topic and will be deleted.

Straight Talkin at 13:59 PM on 2 May 2015Inoculating against science denial
I think you, and the consensus for that matter, are missing the point. I don't agree with the science of human cased climate change because of the consensus. I agree because the science is compelling. All human beings, including scientists, can get into silo thinking and accepted norms. Stop trying to convince everyone that they should believe because 97% consensus of scientists in the field. Outline the scientific reasoning in as clear and simple terms as possible. Educate people effectively. Saying something is fiction based does not make it so. With in the context that they are measured I am sure vaccinations are effective. The real point is how many people were dying per population number. All of them were already very low and dininishing, and had been for decades. The deaths from scurvy tracks perfectly with the death from measles. Vaccinations did not save us from scurvy. The information, IMHO, clearly demonstrate that improved sanitation and nutrition were the key drivers in reducing, and almost completely removing, the danger from these deseases. Besides focussing on the wrong measures, the graphs you quote are classic cherry picking examples.

Tom Curtis at 13:36 PM on 2 May 2015Climate sensitivity is low
bozza @354, even emissions at 10% of current rates would be sufficient to keep on increaseing atmospheric CO2 concentrations, and ergo prevent net ocean outgassing of CO2. The rate of increase of atmospheric CO2 would, however, slow to a standstill in that case - and slow substantially if we only halve emissions. Having said that, the proportion of emissions retained in the atmosphere would not necessarilly remain at the current 55%, and would decrease over time with increasing SST (assuming constant emissions). It follows that while 2100 concentration would probably be below 580 ppmv, I cannot tell you how far. The nearest I can do is show you the RCP 4.5 figures (second graph) as the nearest approximation (first graph).

"...You've limited yourself to such a small dataset that frankly I cannot take any of your arguments seriously.."
Although I'm skeptical of the data quality before this century for the deep ocean, I downloaded the pentadal OHC data and ran a 5 year running trend to convert ZJ to W/m^2 heat input on a global area basis. The results are as follows (TOA CMIP5 ensemble forcing vs NODC Pentadal heat content change, both 5 year periods):
1959 to 2000 - 0.23 W/m^2 from OHC, 0.49 W/m^2 from model forcing
2000 to 2010 - 0.51 W/m^2 from OHC, 0.95 W/m^2 from model forcing
While delta OHC is not global heat content change, it is the great majority of it. Two conclusions seem appropriate:
1. The better the observational data quality, the bigger the discrepancy between model hind/forecasts and,
2. The models run hot.
I can post the graph here if someone lets me know where I might post to the internet so I have a URL link.

Klapper @348:
"You're ignoring my comment above in which I clearly stated the 0.5 W/m2 was the difference between OHC and the TOA model output."
First, you were comparing the difference between model TOA energy imbalance and observed 0-2000 meter OHC.
Second, absolutely right I was ignoring that. Just because you want to compare the model TOA energy imbalance with approximately 80% of the observed energy imbalance (ie, the 0-2000 meter rate of change in OHC) in no way makes that justified. Nor does it justify you comparing model 2000-2015 model TOA energy imbalance with 2005-2010 TOA energy imbalance as you did @325. You seem to have a penchant for strengthening your case by using inappropriate comparisons. However, as you insist that I not use the appropriate comparison because you originally used the inappropriate comparison, I will notice it and call it what it is - ie, fraudulent argument.

I do disagree. Go to the NODC website. You can find a ocean heat data distribution mapping tool you can customize by period. For example, display 1500 metres depth for the period 1968 to 1972. Count the dots in a polygon formed by New Zealand, Ecuador, the Solomon Islands and the Antarctic Penisula. It's not hard to do. Keep in mind each black dot represents one sample, i.e. May 15, 1969.
You have maybe 4 or 5 single samples in this 5 year period between the equator and the Antarctic coast and 90 degrees and 150 degrees longitude west. This represents a huge area with essentially no data in a recent 5 year period.
For a shocking contrast, now retrieve the same depth for 1 year (2014) and try and estimate how many samples were retrieved.

As do we all. And the best data for the last half of the 20th century, while subject to higher uncertainties that current measurements, is worth attention.
Again, differences in the 5-10 (and, grudgingly on your part, perhaps 15) year periods you are looking at are short enough to be entirely unforced variation - with recent work on 21st century volcanic activity (not included in the CMIP5 forcings) that has direct implications for the TOA balance also worth considering. You've limited yourself to such a small dataset that frankly I cannot take any of your arguments seriously.

Klapper @868... Absolutely. And the data we have a decade from now will be better than the data we have today. Today's data certainly doesn't invalidate past data nor would better systems in the future mean current data is bad. The data we have is just what it is at any given point in time. It's always going to be imperfect. Data is imperfect. Models are imperfect.
But again, this is why models are used to constrain those uncertainties. That's "Trenberth's tragedy." Our current systems can't fully account for all the heat in the climate system. That doesn't mean it's not there. That just means that our systems are inadequate.
What is abundantly clear, though, is that adding 4W/m^2 to the climate system is going to warm the planet in a significant and potentially calamatous way.

@Tom Curtis #345:
"..So, even on your figures the discrepancy between mean model and mean observed TOA energy imbalance is substantially less than 0.5 W/m^2 (which as I said before, is a fiction)".
You're ignoring my comment above in which I clearly stated the 0.5 W/m2 was the difference between OHC and the TOA model output. Here's my 2 most succinct posts from the Guardian on the source of the 0.5 W/m2 number:
"All that being said, these studies would agree the heat gain in the measurable part of the ocean is in the range of 0.3 to 0.6 W/m2. If the best guess at ocean heat gain is 0.5W/m2, then where is the rest of the heat? Models show the imbalance at the top of the atmosphere through this period as being 1.0 W/m2. We know the atmosphere has limited heat capacity, and the troposphere hasn't shown significant warming since 2005 in any case. That leaves ice melting."
"However, heat gain by the oceans right now might be 0.5W/m2, which is only 1/2 of the projected TOA energy imbalance, so while the oceans are warming, and the atmosphere very weakly so, together they don't account for the model predicted 1.0 to 1.2 W/m2 TOA net energy input."
I concede in at least one post I used the OHC delta to TOA model as "shorthand" for the global energy delta to model TOA, but it's clear from my initial posts the source of the numbers. You're either not reading my full posts or you're deliberately ignoring the context.

Klapper - We have OHC data of reasonable quality back to the 1960s, as I noted here. What you are considering is far too short a period for statistical significance, hence too short to make broad statements about model fidelity. If you want to make any claims regarding the differences I would suggest using a sufficient amount of the available data.
You're arguing about short term unforced variations, not statistically significant long term climate trends, and your complaints about the XBT data don't change that fact.
