WheelsOC at 03:15 AM on 16 April 2014Climate contrarian backlash - a difficult lesson for scientific journals to learn
Second, the publisher may well have felt compelled to change its story, deviating from the mutually accepted statement, because several of the people involved attacked the journal for its decision to retract. It would not be the first time that a retraction statement is not fully truthful, and that the later statements are closer to what the journal/publisher had considered.
This doesn't seem very likely to me. Up until the second statement from Frontiers in Psychology, everybody's story was the same. It wasn't just the authors of the study, it was Frontiers' own lawyer and one of the peer-reviewers. Both of them corroborated the story that the only issue surrounding the paper before, during, and after its retraction was one of potential defamation liability in the wake of reactions to the paper. They were both part of the internal dialogue about the retraction. At no point was the decision to keep the paper withdrawn ever pinned on anything other than this, even in sources other than the original statement.
If the later statements are truthful in that the higher-ups decided to keep the paper retracted for other reasons, then they apparently hadn't shared this information with their lawyer, their reviewer, or the authors of the paper. -

CBD,
Broken off glacier ends called ice islands and ice bergs are not sea ice, they are land ice. If they are the only ice left than sea ice extent is zero. The extent of these ice islands is very samll, even near Greenland.

Marco at 01:50 AM on 16 April 2014Climate contrarian backlash - a difficult lesson for scientific journals to learn
I am going all contrarian here.
First, "the journal" when referring to Frontiers is wrong. None of the people who resigned are from the journal that published the Lewandowsky paper (Davis coming closest as an editor of a sub-publication of Frontiers in Psychology". Please get that fixed.
Second, the publisher may well have felt compelled to change its story, deviating from the mutually accepted statement, because several of the people involved attacked the journal for its decision to retract. It would not be the first time that a retraction statement is not fully truthful, and that the later statements are closer to what the journal/publisher had considered.
To be quite honest, there are a few situations around the paper that make me uncomfortable. While the conclusions and analysis may be sound, in my opinion it was improper for several of the authors to interact with their study objects. I don't buy the "psychopathological characterization", but I also don't buy the paper to be an objective analysis. Lewandowsky should have known better and asked a third party to do the analysis.

One Planet Only Forever at 00:00 AM on 16 April 2014Climate contrarian backlash - a difficult lesson for scientific journals to learn
This article presents a good case study of highlighting some of the many fatal flaws of the current dominant socioeconomic systems. It highlights the expected result of a system that enable pursuers of unsustainable and damaging actions to viciously compete to benefit and become powerful. It shows how “uncaring vicious pursuers of anything they can get away with” will viciously abuse the power they get away with getting, including using any potential fiscal/legal threats they can get away with to keep the population less aware of anything contrary to their interest.
It can also be shown that those type of people try to ensure effective promotion/threat mechanisms are developed that they have more ability to benefit from than those who would try to develop a sustainable better future for all.
The obvious conclusion is that the socioeconomic systems “cherishing image over substance” combined with promotion of “personal freedom to enjoy the best life any way you want” leads to unacceptable actions being popular and profitable. Unacceptable unsustainable ad damaging behaviour should simply not be accepted, yet those wanting to maximize their lazy harmful ways of benefiting often succeed in getting popular support for a “balance”, meaning doing something contrary to the best understanding of its unacceptability and risk of harm.
That is why so much of the current developed economy is fundamentally a threat to the sustainable growth of the economy. Fundamentally unsustainable and damaging activities cannot possibly be expected to develop toward a sustainable better future for all. Such a future will fundamentally not be in the interests of many of the pursuers of profit through popularity. And those who do not care about the sustainability and damage of their desired actions have a competitive advantage, and they will viciously fight to "enjoy the best possible life for themselves" for as long as they can get away with any way they can get away with.
This is nothing new. History is full of observations of the unacceptable results of allowing “some people” to get away with doing as they please. The record of human thoughts includes clear statements of the threats such people pose. And yet today we see that attitude being admired with many people desiring to be like that. Whenever those type of people succeed everyone else suffers, especially the future of humanity. That is clear. And it is also clear why such clearly understandable things are “unpopular” and viciously fought against.

CBDunkerson at 22:22 PM on 15 April 2014Arctic sea ice has recovered
Interesting aside: When nearly all of the sea ice has melted out, the last remaining bits will be large 'ice islands' of very thick ice broken off from land. At that point, the 'multi-year ice' in summer will be near 100% while the ice extent and volume will be near zero.
I suspect that in the upcoming years we'll see a trend of growing percentages of summer multi-year ice (and average ice thickness). Not because the ice is 'recovering', but simply because the thicker multi-year ice will be the last to go.

CBDunkerson at 22:13 PM on 15 April 2014Arctic sea ice has recovered
The 'significant increase' seems to have gotten us back to ~ March 2008 multi-year ice levels... yet PIOMAS shows that after the 'high' ice volume at the end of last summer's melt, the final March 2014 volume was lower than every previous year except 2011.
That seems contradictory... until we consider that the multi-year ice chart shows percentages. The percentage of the ice which is now multi-year is similar to what it was in March 2008. However, the total amount of ice has decreased and thus the 'same percentage' actually means less multi-year ice. This can also be seen on the PIOMAS average ice thickness graph. There, 2014 is higher than all years since 2008, but significantly below 2007. The average thickness has increased because the percentage of thick ice is higher while the total ice volume has declined.
Volume will always be the determining factor because it quite simply is the amount of ice. The fact that the volume at the end of March 2014 was slightly lower than that of March 2012, which went on to have the lowest summer volume (and extent) ever, tells me that there has not been any 'recovery' in sea ice. We are at essentially the same place we were in 2012. Thus, if we again see weather conditions like that year we could again see new record lows this year. If we get better weather conditions maybe we'll start to see an actual recovery in a few years, but it clearly hasn't happened yet and doesn't seem likely to as the planet continues to warm.

Harry Twinotter at 16:04 PM on 15 April 2014Climate contrarian backlash - a difficult lesson for scientific journals to learn
"... bullying by contrarians over a paper ..." I am still not convinced that pressure has come from "contrarians" as such, more like the pressure has come from conspiracy theory proponents who feel they have been slighted. Maybe someone can clear this up for me.
My own "conspiracy theory" is I can understand why Frontiers is nervous about any legal action. Such action would get a lot publicity as it is connected to Climate Change, and the claimants may well get a lot of anonymous financial help to pursue their lawsuit. -
michael sweet at 11:20 AM on 15 April 2014IPCC says adapt and mitigate to tackle climate risks
There are often discussions about Nuclear on these threads. It then becomes hard to find the previous posts because nuclear is not in the title. No-one has appeared to write an opening post for Nuclear Power. Perhaps a thread could be created with a title like Benefits of Nuclear Power without an OP so that all these comments can be in the same place. Then we could refer to that thread and not have to re-do all the comments over again.

johnthepainter at 11:17 AM on 15 April 2014Climate contrarian backlash - a difficult lesson for scientific journals to learn
Thanks for the two related articles, which do a useful service in demonstrating that not only does the research concluding that human activites have little effect on climate change, or that it is nothing to worry about, comprise only 3% of published research in this field, but that these studies are also of inferior quality, and many have been shown to be simply wrong. This point has been made before, but it receives little attention in the news most people hear or read.

There's an interesting post or two by Tamino noting that ice variability greatly increased around 2007 - smaller amounts of ice are simply going to be more affected by yearly weather.

IPCC says adapt and mitigate to tackle climate risks
LCBozo - Regarding your throwaway "the "station black out" fossil fuel generators" statement see this comment on a more appropriate thread; a study of using renewables in the western US grid found that "...the carbon emissions induced by more frequent cycling are negligible (<0.2%) compared with the carbon reductions achieved through the wind and solar power generation evaluated...". In other words, a huge gain from renewables.
Further discussion of renewable baseline power really should take place on the appropriate thread, after reading, to avoid repetition. Suffice it to say that it appears quite feasible both technically and economically.
As to nuclear waste, while it might be future fuel (Transatomic Power has some interesting proposals, although I don't know how far along they are), you cannot legitimately ignore the costs involved in waste storage, waste reprocessing, and disposal of final nuclear ash and decommissioned powerplants. Nuclear is certainly worth considering as part of the solutions to GHGs, but over-optimistic numbers for any proposal are not terribly helpful.

Rob Honeycutt at 06:21 AM on 15 April 2014Arctic sea ice has recovered
Note that the NSIDC states along with the graphic Juan presented...
"The percentage of the Arctic Ocean consisting of ice at least five years or older remains at only 7%, half of what it was in February 2007. Moreover, a large area of the multiyear ice has drifted to the southern Beaufort Sea and East Siberian Sea (north of Alaska and the Lena River delta), where warm conditions are likely to exist later in the year."

Rob Honeycutt at 06:06 AM on 15 April 2014Arctic sea ice has recovered
Juan_H... It's nice to be optimistic but this is unlikely to be anything more than a temporary change. We're still likely looking at seasonally ice-free conditions starting around 2030.
It's just that, on the way to the bottom the numbers are going to bounce around like this.

Rob Honeycutt at 05:49 AM on 15 April 2014IPCC says adapt and mitigate to tackle climate risks
LCBozo... "...I am opposed to the belief that [wind energy] can even come close to solving any significant fossil fuel generation replacement, without some significant "unintended consequences.""
Can you name one solution that would not have any unintended consequences? Certainly not nuclear.
I will reiterate here again, the answer is not A or B or C. The answer to dealing effectively with climate change is A and B and C... and best throw in a D and E while we're at it.
All solutions are needed, and needed now. We need to put a price on carbon and then watch the marketplace do the job of deciding which technologies are going to be the big winners.
We can go back and forth all day long about which technologies are better and which have unintended consequences, but at the end of the day we just need to move forward with all of them.

LCBozo at 04:56 AM on 15 April 2014IPCC says adapt and mitigate to tackle climate risks
I was hoping for a bit more objectivity. If one looks at the percent of power generation by wind, and the required expansion of that energy source to realize any real impact to eliminate, for example, dirt burners, one can then tally-up the flying species death results. I won't even get into the environmental esthetics. One might also take a look at the "station black out" fossil fuel generators for the complete picture of wind and solar generation.I'm not at all opposed to wind generation, but I am opposed to the belief that it can even come close to solving any significant fossil fuel generation replacement, without some significant "unintended consequences."I would not endorse more of the present massive scale light water reactors. They represent the influences of a very biased Admiral Rickenbacker. As I stated, a huge percent of construction, operational, and maintenance costs of modern reactors is the nuclear steam supply systems. The sodium cooled FFTF had a full power operational maximum pressure of about 100 PSIG. It also used an electromagnetic RCP. It did not have a secondary steam supply system, but the primary PWR or BWR steam systems are the really expensive part of the light water equation.The cost of PVNGS construction was lower in the late '70s to late '80s, about $6 billion for all three units. Once these plants start generating power, they generate massive amounts of money and electricity.From Wikipedia — which correlates close to the APS data on PVNGS power production (part of our annual incentive payout (bonus) was based on cost per kW hr."The Palo Verde Nuclear Power Plant supplies electricity at an operating cost (including fuel and maintenance) of about 1.33 cents per kilowatt-hour.[6] This is cheaper than the cost of coal (2.26 cents per kW•h) or natural gas (4.54 cents per kW•h) in the region as of 2002. However, this power is more expensive than hydroelectric power (0.63 cents per kW•h). Assuming a 60-year lifetime for this power plant and five percent long-term cost of its capital, the depreciation and capital costs not included in the previous marginal cost for Palo Verde are approximately another 1.4 cents per kilowatt-hour."With upgrades over the last decade, PVNGS continuously generates about 4 Giga watts of electrical power. This is about 36% of the total used in the state of AZ. If solar were to replace PVNGS, it would take about 10 Agua Caliente Solar size plants (397 MW when completed this year). The finished cost of Agua Caliente Solar Project is (so far) going to cost about $1.8 billion. To replace PVNGS with solar would cost $18 billion for construction alone. I can (as a maintenance engineer / planner) assure you, that massive volume of solar panels and related inner/outer power distribution, controls/electronics, will cost more per megawatt to keep running than any modern nuclear power plant. Also, 10 Agua Caliente Solar Projects would cover such a huge area of Sonoran Desert, that it would represent an environmental issue.Had I retired in AZ, we were planning to put at least 6 KW worth of solar panels on our home roof. This is a great way to add clean power to the existing grid, and keeps the power distributed to individual home owners, not another government favored utility corporation. -

Here's the latest "knock down evidence" against AGW theory from the skeptic camp. Have you guys seen this one yet?

Glenn Tamblyn at 22:55 PM on 14 April 2014Climate imbalance – disparity in the quality of research by contrarian and mainstream climate scientists
PluviAL
In 1982 the concept of CO2 Induced climate change wasn't that new.Arrhenius had suggested it in 1895. Callender thought about it in the 30's,. Gilbert Plass and others such as Bert Bolin were exploring it in the 1950's, Manabe & Wetherald put it on a solid footing in 1967. The President's Scientific Advisory Committee warned of the possible risk in 1965.

PluviAL at 13:07 PM on 14 April 2014Climate imbalance – disparity in the quality of research by contrarian and mainstream climate scientists
In 1982, the relatively new concept of CO2 induced climate change was intuitively forecasted. One prediction was a large volcanic eruption in early 1990s that would help scientists calibrate models. Pinatubo happened and Jim Hansen calibrated his models and became a motivated desciple of climate action.
The conclusion of the forecast was that civilization would either put a tax on carbon or fail in controlling climate change. The other pertinent forecast was that the arc of interest in the subject would mature in the decade of 2000 to 2010. Civilization has not really activated a tax on carbon.
Now as public interest in the subject wanes, according to the old frecast, will we successfully tax carbon? Has civilization failed to act on time to avert feedback loops that will through us into chaos?

Noel Wauchope at 13:05 PM on 14 April 20142014 SkS Weekly News Roundup #15B
The Internet is actually awash with articles about thorium - all praising it.
But the general theme is always the same.
Thorium reactors are basically a form of REPROCESSING
Reporocessing is pitched as the alternative to deep burial of wasters.Big pitch going on in UK - where local opposition to waste burial is strong.
So - the whole thorium thing is about a way to keep the nuclear industry going, rather than shutting it down
It's about persuading the world that wastes are not wastes, but are valuable resources.
An attractive story - as it solves the problem of local opposition to waste burial sites. Conveniently ignores the fact that the thorium reactors themselves produce become wastes - that will need burial.
All this would mean that the problem of wastes is passed on to future generations.
In tandem, goes the story that ionising radiation is OK - it is after all "background radiation". For an example of what a lie that is, consider Caesium 134 and 137. It did not exist on earth until nuclear fission. All the caesium 137 and 134 now in water soil air - all came from a nuclear power source - largely atomic bomb testing in the 50s and 60s.
Now - it's all "natural" - background radiation. And now radiation at low levels is not a worry anyway.
Two lies working together to keep the nuclear industry going. One could add the lies about the ineffectiveness of energy efficiency and renewable energy

"his appointment, though, does suggest the project has political clout. The team plan to fire up a prototype thorium reactor in 2015. Like India’s, this will use solid fuel. But by 2017 the Shanghai Institute of Applied Physics expects to have one that uses a trickier but better fuel, molten thorium fluoride."
The plan is to come up with a design by 2015 - not an actual operating reactor
." But a better way is to turn the element into its fluoride, mix that with fluorides of beryllium and lithium to bring its melting-point down from 1,110ºC to a more tractable 360ºC, and melt the mixture"
The plan is to work out how to do this temperature reduction - hasn't actually been done yet"there is less than a hundredth of the quantity and its radioactivity falls to safe levels within centuries, instead of the tens of millennia for light-water waste".
This is actually not true. Yes, the volume of wastes is smaller, but it is so intensely radioactive that it requires the same size of containment as the original wastes would. Some of the fissile products do last for thousands of years, e.g technetium-99 (half-life of over 200,000 years)And the pitch about 'only centuries' is revealing - do we want to have to guard these wastes for centuries? Is that OK?
Not able to be turned into weapons? In fact, it can be done . It's just more difficult.
Left out of this argument is the constant need for plutonium and/or enriched uranium to keep the fissile process happening.
This means a source of plutonium/enriched uranium nearlby - this means not only import of these but a continuous terrorism risk . The thorium reactor and its ancillary sources and eventual wastes form a lovely terrorism target. Even more fun , if there are dozens of little reactors.

This is a rather poorly written article about the most recent publication by Mike Mann. The author does not even mention Mann's name. Also the secondary conclusion of this publication is not mentioned: the debunking of a famous "Stadium Wave" hypotehesis by Judith Curry. Mann has shown that "Stadium Wave" hypothesis a byproduct of incorrectly applied statistical analysis. Curry will be fuming and we have another nail to the coffin of a contrarian hypothesis.

Concerning the Thorium reactors the problem with any radioactive substance is that the waste material can be used by terrorists as a weapon irrespective of any explosive capabilities. It only needs to be ground into a fine powder and dispersed in the air.
I don't know how radiogenic materials are stored but it's not likely to be well guarded.

I'd be interested to know what percentage of the contrarian papers have since been found to be incorrect? Are there any that have not?
I guess one could ask the same of those papers affirming the climate science, although that might not be so simple a task given there are so many.
This point may be have been addressed in the paper itself, which I am unable to read as it requires a subscrition at the moment.

One Planet Only Forever at 02:45 AM on 13 April 2014Climate imbalance – disparity in the quality of research by contrarian and mainstream climate scientists
It is clear that some people will not “change their thought processes and motivations” just because the better understanding of all the available information contradicts what they prefer to believe (or in this case what they want others to believe). Only when these people among the “contrarians to climate science” are acknowledged as being irrational is there hope that they would begin to more rationally pursue the best understanding of the issue, even when that better understanding will result in them rationally understanding the loss of personal opportunity for maximum benefit from unsustainable and harmful activities that is required by that better understanding.
It may be helpful to use a different term to refer to people whose actions indicate a high degree of certainty that they are not genuinely interested in developing a continuously improved best understanding of what is going on, motivated by a resistance to the changes of human activity that is required by that improved understanding.
Maybe “deliberate irrational objectors” should be the term for people who strive to create doubts regarding the best understanding of the results of the climate science even though their familiarity with “all of the available information” should not lead them to try to make the claims they try to get away with. These are people who deliberately object to the understanding that would result from a reasoned and rational evaluation of all the available information. And their motivation for being “deliberate irrational objectors” is clear. The current developed socioeconomic system created a lot of people who desire the personal benefits they can obtain from deliberately pursuing benefit from unsustainable and harmful actions. That is a very powerful motivation. And the deliberate irrational objections it can lead to must be recognized and called what they most likely are.
Having said that, the term deliberate irrational objector can be manipulated to lead thoughts away from the intended description of the person, to make it seem disparaging or unfair. It almost becomes necessary to describe the term every time it is used to make it more difficult for the deliberate irrational objectors to deliberately irrationally object to it, but they still will try.

As wrong as this may sound, I don't think we can ever expect people to do anything. If governments won't do it, it won't get done. The only way I could see this working is if there became a contract between nations that sign up to reduce carbon which only allows them to do 80% of all business between each other.

funglestrumpet at 20:23 PM on 12 April 2014IPCC issue official rebuttal to more David Rose/Daily Mail nonsense
Rodger D @ 13
And he would probably be able to find a quote from one of the all too many 'guns for hire' so-called experts that say that the sea-ice was not bouncing back and indeed, like the surface temperatures, was extremely variable. Being able to prove one's point by turning to the science of an issue, does not automatically result in public acceptance. If it did, they too would be 97% in favour of urgent action to combat climate change. The only reason that I can put it down to is that the media have undue influence, which they abuse, and an all too gullible public acceptance ot their output. The Mail group is far from unique in this matter. If Mr Rose and all those like him, including peers of the realm, could be shown to the satisfaction of a jury that they had deliberately made statements that they had to have known to be false, then I see that as worthy of sanction. Others on this site disagree with me. But I am sure that if such sanctions had been in place from long ago, we would today have a much better informed public and a political class much in fear of losing votes if they did not act on the matter. I think that that loss of freedom is a price worth paying if it saves lives.
Scientists themselves are not immune from being influenced by the media. I am confident that the majority reading this will believe the official line on 9/11 and see conspiracy theorists, such as myself as tinfoil hat wearing loonies. Yet if one turns to p45 of NIST's Final Report on the collapse of WTC7, one will find that NIST (reluctantly) accept that it collapsed at free-fall acceleration for 100 feet. In truth, all I have done is what I always try to do, namely see what science has to say. this time it says there has to have been an input of energy sufficient to remove the tens of thousands of tons of structural steel and concrete that was stopping the building from collapsing at all. Hence my position that, nukes, directed engery beams, aliens etc notwithstanding, WTC 7 was brought down by the use of explosives. I mention that only to make the point that even scientists can be fooled if they drop their guard. (The price of "freedom etc.")
As for your comments on Tverberg, as you say, you are no expert. What I was suggesting was that her work needs to be professionally debunked or accepted as valid. It will be something that the faux skeptics will latch onto sooner or later and it would be better if this side of the fence were not caught on the back foot. One thing is very clear is that oil will become more and more scarce with a consequent effect on transport costs, that will in turn screw up economic growth, cause a retraction from globilisation and generally disrupt how economies operate. And all that at a time when interests rates will start to climb and the little bits of paper that we call money will eventually be seen for what they are: only little bits of paper. That will surely have an effect on BAU and with it carbon emissions. I just think it would make sense, if valid, if those notions were built into the climate models. We will only be able to validify them by investigation, which is what I am suggesting. The last thing we need is for the media to have yet another reason to knock the IPCC. I can Mr Rose sharpening his quill even as I write.

Tom Curtis at 12:07 PM on 12 April 2014Climate Models Show Remarkable Agreement with Recent Surface Warming
Klapper @59:
HadISST1: ENSO (the El Nino Southern Oscilation) is no more directly measured by a pure El Nino/La Nina index than it is by a pure SOI index. Further, the El Nino fluctuations themselves are caused by changes in the strength of the Walker circuation, which is caused by changes in pressure between the Central and Western Pacific. Thus the SOI measures a direct link in the causal chain of El Ninos. The change in relative pressure may be caused in part by changes relative changes in temperature. Relative changes in temperature are no measurable by taking the average SST of a small area. Your claim that NINO 3.4 measures a direct forcing is false. Indeed, it is the SOI that measures a direct forcing, rather than NINO 3.4. Had you used the Trans Nino Index (TNI), you would at least have an arguable case ("arguable" in that it is not clear that the relevant areas are the best for measuring the causality).
PDO: The PDO is closely entwined with ENSO, but it is not clear in which direction the causation flows. It is also irrelevant in that once you have included the ENSO signal, you have de facto included the PDO signal on global warming as well (because they are so closely entwined). Therefore the PDO is a distraction in this discussion.
Error: If the baseline error results in models over stating warming, variations around that baseline will bring models and observations into close agreement, or great divergence. Thus, if the baseline trend in observations is 0.17 C/decade and that in models is 0.2 C/decade, a +/- 0.04 C/decade influence on the observed trend will result in discrepancies between -0.01 and + 0.07 C. Such variations are not arguments to think the baseline discrepancy is more than about 15%. Rather they are reasons to think that it is about 15% +/- 15% - where the +/- represents not the error in the estimate but the variation around the baseline discrepancy.
This is the last time I will make that point. If you cannot see that by now, it is because you will not see it. The possibility that the model error is not large is too uncomfortable for you to deal with, so you reject it regardless of the evidence.
""models over estimate cooling from models": Sorry for that. My previous post was written early in the morning after an entirely sleepless night due to insomnia. As a result a number of mistypings crept in.

Roger D at 10:08 AM on 12 April 2014IPCC issue official rebuttal to more David Rose/Daily Mail nonsense
Under the hypothetical future you note in your post, you believe Rose would be able to "say with some pride that he used his skills in the only way he knew how" to keep his family from poverty. Really? He could not find another avenue, that would not involve repeatedly trying to confuse his readers to keep his family out of this hypothetical poverty? I doubt that.
To continue the conversation, I think a reasonable response from his offspring to such a contention from Rose would be: "Dad, what were you thinking? I mean, this article for example on how sea ice is bouncing back is obviuosly disingenuous based on the information available to you at the time; it is misleading. Did you really have to put that stuff out there? You are not a stupid man. I reject that you had no choice and reject that you didn't know you were wrong to do it. Don't put it on me."
As for Tverberg's contentions, I'm no expert on peak oil, etc, but she seems like she is probably an outlier from her peers. Her graph of Estimate of future energy production in the event of an economic crash driven by factors that result in drastically lower oil (and other?) energy use which shows a sharp, steady decrease in total energy production beginning in a hypothetical 2015 crash and declining to 1970 level within 10 years would obviously mean society is struggling. But that's a big IF to essentially "count on" when something closer to BAU, which seems more likely, will result in serious problems for societies.

chriskoz at 09:21 AM on 12 April 2014IPCC says adapt and mitigate to tackle climate risks
An interesting, well balanced article at popsci.com.au talks about wind industry impacts on bats:
Wind Turbines Kill More Than 600,000 Bats A Year. What Should We Do?
So the problem is not about infrasound as FF monguls and climate science deniers claim (debunked by DB@23); the problem is about "barotrauma" - the extreme barometric stress on small species due to sudden air pressure fluctuations up to the point thier lungs can explode. The small migratory species like hoary bats are mostly affected. The disturbing aspect is that we don't even know the percentage of population being killed so we don't know the extents of the problem. But according to the precautionary principle we should still restrict the deployment of wind farms in the affected areas.

One Planet Only Forever at 08:41 AM on 12 April 2014IPCC says adapt and mitigate to tackle climate risks
PluviAL @21,
I am not opposed to civilization, or popularity, or pursuit of profit as long as all humans limit their activities to truly sustainable actions. I point out that those who will not limit their activities in that way are the only real problems (trouble-makers), on this planet. And the system of values they want needs to be changed. They need to adapt to a sustainable reality, even if they don't want to.
I do not consider your comment to be a valid rebuttal of my criticisms of the current socioeconomic system and the results it develops. Please provide specific proof that the pursuit of popular interest or profit based on the current method of deciding value has any potetial to generate a sustainable better future for all, keeping the following in mind.
The damaging and unsustainable ways to get pleasure, comfort, convenience or profit will always be cheaper, more popular and more profitable in a system that fails to account for all impacts, particularly one ignoring the using up of a limited opportunity to the bitterest of its ends of potential benefit, no matter how damaging the activity is, just because it is something that can be gotten away with (The global easy to get helium, critical for medical uses, is being consumed by party balloons? Absurd, yet the natural result of pursuit of popularity and profit limited to the concerns of only a portion of the population and to their personal lifetime).
The only valued activity should be improved ways of living that can be chosen to be done by all humans forever on this amazing planet without reducing the amount or diversity of life. That means that the first measure of acceptability of any activity would need to be conclusive proof that the entire human population can develop to do the activity and continue it forever, until something sustainable but better was developed. And that would also require the curtailing of any activity that had been gotten away with but was learned to be unsustainable and damaging.
The filter to ensure that only sustainable human activity occur compete is deliberately not in place. Many among the wealthy and powerful do not want to adapt to limiting their opportunity in that way (they want all the freedom they can possibly get away with), mainly because they know they don't have what it takes to succeed in that type of competition. THey even fight against the development of better understanding of the uacceptability fo what they have been getting away with.
Pluvenergy, and nuclear, and any other human activity on this planet should first have to pass the true sustainability test. Then the competition of popularity and a profit system would become more relevant. That would liklely result in less energy consumption, meaning not living in places requiring larger amounts of energy consumption. It also would mean less consumption of other things (and consuming better quality and more durable things), and no consumption of non-renewables (full recycling as a last resort of acceptability). That adaptation of lifestyle may not be as popular or as profitable as the things that can currently be gotten away with, but at least it could last and be enjoyed into the future.

funglestrumpet at 07:48 AM on 12 April 2014IPCC issue official rebuttal to more David Rose/Daily Mail nonsense
"However, one thing is for certain: these actions, once committed, are written into history and so can never be undone. Whatever the outcome of the climate crisis, once recorded, they will not be forgotten. One cannot help wondering if that is how some people really want to be remembered in future."
Why on earth should Mr Rose worry about the future when he can point to a body of opinion that supports his stance on climate change? He earns his money today by writing such pieces that are the subject of this posting. If his children do raise the issue with him at some future date, then he will be able to point to the soup kitchens, the homeless, the food banks, etc., which are also written in history, and say with some pride that he used his skills in the only way he knew how to keep his family from having to use them. He doesn' even face sanction from society as a whole or from his profession, if it can be described thus.
Sks readers might dislike Mr Rose, but the readership of this blog are vastly outnumbered by the readership of the Daily Mail, not to mention the Mail on Sunday and those who prefer the output of the Murdoch empire. Even if one tries to get some movement from the scientists involved in climate change, one gets told in no uncertain terms that free speech must rule the day. I'll get my son to put words to that effect on his gravestone, if climate change takes him.
However, it seem much more likely that economic collapse will probably get him first. According to <ahref="http://ourfiniteworld.com/2014/04/11/oil-limits-and-climate-change-how-they-fit-together/#more-38919">this</a> article by a highly regarden actuary, Gail Tverberg, who specialises in climate change, among other issues, climate change will soon by the least of our worries.
She sees the IPCC RCP2.6 scenario as the most likely way temperatures will go. I don't know whether she is correct, but she certainly tries to support her views scientifically. The referenced article is only the latest in a series of postings by her that seem to draw largly favourable comments. Those who follow the link will find that it centres on climate change and how oil supply, or rather the lack of it, is going to have a much more dramatic effect, and much sooner. Sorry if this is off-topic, but I think it is important that climate scientists study her work and either debunk it, or see that it is taken into consideration. I know from a lot of other sources that BAU is thought highly unlikely by many in the financial sector.

LCBozo@8
I think I understand what you are saying. Still, it's important, I think, to remember that Darwing proposed his theory with no real way to explain how it worked. In other words, the only real doubt about it on this planet was put to bed with the discovery of DNA's role in life. Up until we understood that DNA carried the inheritable information and genetic variation that all living things pass along to their offspring and in doing so allow for evolutionary change, Darwin's theory was in that sense a theory without a known causal mechanism to explain how it worked, but that no longer applies. Thus, we can confidently say that Darwin' explanation is supported by all the relevant facts. In this sense, Darwin's theory is fact-based, or true, or correct, or, in fact, is a fact of life since there is no other plausible explanation outside of the realm of religion. Thus, I think the debate about fact versus theory on this topic is about semantics.

Daniel Bailey at 05:39 AM on 12 April 2014IPCC says adapt and mitigate to tackle climate risks
"There's no need to be a conservation science denier, as Bailey is."
Strawman. I make no claims as to downplaying conservation science or being a pro-windpower advocate to the extent of minimizing their environmental impacts upon aviation populations. The organized attacks on climate science by fossil fuel-funded outlets include attacks on renewable energy. The parroting of unfactual and context-less birdkill information is just carbon-hype when the actual context is examined. Context I endeavored to provide in this thread.
And it's "Daniel".

Seeing Mike@4's comment about the change puts me in mind of Winston Smith and Orwell's 1984. I wonder if the Mail and other publications with sad denialist records on this topic, won't simply delete all their bilge when they eventually give in to reality. Clearly, it would be easy to do.

I would acknowledge the "Black Swan" principle when assigning % probabilities. Would a physicist claim there is a 99.9% probability that gravity exists? The existence of evolution is a fact, how it works is a theory. We can't assign such probabilities, as it presupposes we have some knowledge of what the 100% would be in the first place. -
localis at 05:21 AM on 12 April 2014Climate imbalance – disparity in the quality of research by contrarian and mainstream climate scientists
quote: "Despite the 97% expert consensus on human-caused global warming supported by peer-reviewed research, expert opinion, the IPCC reports, and National Academies of Science and other scientific organizations from around the world, a large segment of the population remains unconvinced on the issue."
I guess a large segment of the population (ie.the majority) aren't even aware of the evidence regarding AGW one way or the other. I think we kid ourselves that far more people share our concerns or interest in climate change than actually do. Not only do we need to silence the damage done by deniers we need to convince many that they need to start considering the issue in the first place.

@2 and 3. The likelihood that climate change is happening amd man made is > 95%. The likleihood that evolution is true is close to certainty that I would not know how many nines to put after 99.9%. The fact that people choose to put dogma before reality is depressing and sadly means that getting robust climate change policy will be an uphill struggle for years to come.

IPCC says adapt and mitigate to tackle climate risks
dhogaza - I would note that your response to my comment is (a) to a large extent not responding to what I wrote, and (b) rather over the top in tone. "Do you think they're stupid, or what" and "Real Scientists (assuming you can accept the possibility that a biologist can be a scientist) do study these things" are rather insulting statements - I do not think they are justified from what I said.
What I said was that the raw numbers for cross-species bird kills shows a four order of magnitude difference between wind power and other factors, and that with only that information there is little indication of threat to specific species. That requires specific studies of those species, their habitat intersection with wind power, evaluation of whether their flight profiles are at an altitude threatened by wind power, and most importantly data about species kills. Data which you have only now provided a (single) link to - you had not previously.
In reference to the prairie chickens, for at least the greater prairie chicken, Sandercock 2013 notes "wind turbines have little effect on greater prairie chickens, and that these grassland birds are more affected by rangeland management practices and by the availability of native prairie and vegetation cover at nest sites". That seems to be the case for the various references I found for the lesser prairie chicken, that the threat to them is far more about habitat (their range needs and their avoidance of tall structures as potential raptor sites) than about bird kills from collisions with either the blades or towers. Results like these make habitat preservation an important aspect of wind power.
An interesting discussion - but please ramp down on the rhetoric and tone.

dhogaza at 03:59 AM on 12 April 2014IPCC says adapt and mitigate to tackle climate risks
Let me finish by pointing out that conservation scientists understand that most wind farm installations do not cause significant impacts on populations of birds at risk.
The problem is when people like David Bailey extrapolate this to mean that no wind turbine installations can cause significant impacts on populations of birds at risk. Further extrapolation leads to claims that we don't need to take threatened or other at-risk species into consideration when siting wind farms, nor do we need to monitor or study impacts.
Wrong.
In reality, most siting studies tend to show that a given proposed wind farm doesn't pose a significant risk. Most. Not all.

And, yes, Real Scientists (assuming you can accept the possibility that a biologist can be a scientist) do study these things. There's quite a bit of literature out there. Here's just one example:

dhogaza at 03:40 AM on 12 April 2014IPCC says adapt and mitigate to tackle climate risks
KR:
You could start by asking why the industry always states that a lot more birds are killed by other causes rather than detail mortality by species.
Do you think they're stupid, or what?
"Do you have comparative mortality factors specifically for the lesser prairie chicken?"
lesser prairie chicken is already listed as a threatened species under the ESA. By definition every dead prairie chicken is more important from a conservation point of view than the death of, say, a starling.
"Given the four orders of magnitude higher bird kills by other factors"
Wow, four orders of magnitude!
There are only a bit more than 17,000 lesser prairie chickens in the wild. There are 150 million starlings alone. I will let you calculate how many orders of magnitude difference that represents.
Bailey includes tidbits such as:
"Cat's out of the proverbial bag. Per Loss et al 2013, feral cats kill most of the 87,000 times as many birds (in the US alone) than do all of the wind turbines in the world do, combined."
Again, no mention of species distribution, and again, this is intentional.
There is also this from Bailey, which is downright offensive:
"But climate deniers aren't interested in facts that disagree with their desired outcome."
I am no climate denier. The wildlife biologists I know are not climate deniers. I am not anti-wind power, nor are the wildlife biologists I know and have worked with over time in conservation contexts.
On the other hand, one might claim that those that equate a single starling death with that of the death of a member of a highly threatened species like lesser prairie chicken is a conservation science denier.
I'm used to this crap, being labelled "anti-environment", "climate science denier", etc simply because I point out that wind turbines are an important source of mortality for certain species at risk in certain portions of the country. The industry and friends began labelling conservation biologists as being "anti-environmental" (think about that for a minute) over two decades ago. The industry itself has reluctantly become more self-aware over time. People like David Bailey not so much.
"climate denier". Harumph. Stuff it.
Regarding Altamont, Bailey is trumpeting the success of mitigation (much better siting, removal of the old derrick-style supports that provided perches for perch-hunting species like red-tails, etc etc).
This is good news. Wind power supporters like myself who also understand conservation issues regarding certain species of birds have been very happy that newer windmill designs, attention to siting, etc have improved the situation.
We can have wind power and we can mitigate bird mortality if we pay attention to detail. There's no need to be a conservation science denier, as Bailey is.
