Daniel Estrada29,886// Continuing a long conversation after a brief intermission! See more here:https://plus.google.com/u/0/events/cjhsk41gv6ggn3sbdubq2klmrc0> This week an announcement rippled through the internet: a computer passed Turing's test. Soon after the backlash began: the test was rigged, the resulted were hyped, and Eugene, the machine in question, was lame. Now the backlash is giving way to even stronger criticisms. +Massimo Pigliucci recently argued (http://goo.gl/VdilBI) that not only was this test illegitimate, but Turing's test itself should be abandoned. But Massimo's argument is deeply mistaken about the nature of Turing's test, what it seeks to prove, and why it matters for science. I've been writing all week about this event:http://goo.gl/J26xbs, http://goo.gl/5RKIm7, http://goo.gl/c07lLG, http://goo.gl/T98ubJ, http://goo.gl/8cMKSIBut now that the backlash against the event is directed at Turing's views themselves, I feel something more than an essay is required to address these concerns. To be convincing, this requires a human face and a human voice to speak out in defense of Turing's proposal.I'm fully aware of the irony of this situation. So come hangout with me and +Jon Lawhead this Friday at 10pm EST while I defend Turing's proposal in light of the criticisms that have accrued over the last week. I'll be providing a defense of Turing's position informed by recent experimental work in psychology. I hope to convince even the skeptics like Massimo that Turing's test deserves a central place in our discussion of artificial intelligence in the modern world.

Fraser Cain824,747Super Science Circle for October, 2013I know it's been a while, so it's time for a new Super Science Circle - the October 2013 edition.In case you weren't aware, the Super Science Circle is a list of more than 400 people who are actively engaged on Google+ and regularly post about science and education. We've got journalists, scientists, even a few astronauts. The Super Science Circle should be your best response to anyone who tells you that Google+ is just a ghost town. If you love science, this circle will deliver the goods.If you know anyone who actively posts about science, please let me know and I'll add them to the list.2013-10-04 20:14:53415304682

I may have missed some people due to limitations of the G+ interface, but as usual, everyone who reshared last week's version of the circle has been included this time.As always, reshares are appreciated.

I may have missed some people due to limitations of the G+ interface. I'm pleased to see that this week's circle contains quite a few scientists.Circle tip of the weekAre you experiencing the problem of not being able to add people to your circles, even though you haven't altered your circles within 24 hours, and you aren't near the 5000 limit? The following steps may help.1. Take one of your circles that contains close to 500 people, and share it as a private post to yourself.2. Remove the whole circle in your Google+ Circles pages.3. Wait at least 24 hours.4. See if you can now add people. If you can, you can gradually add back the circle you previously deleted, by using the privately shared post in step 1.If that worked for you, you can thank +Circloscope for the tip. And, as always, thanks for reading my posts!2013-07-28 05:43:40477300112241

So there was thirty years of cooling followed by 20 years of warming and almost 18 years of cooling…and that’s what the global warming scare is all about. Antarctic Sea Ice is at record levels and the Arctic ice cap has seen record growth. Global sea ice area has been averaging above normal for the past two years. 

Carbon Dioxide (CO2) is not a pollutant it’s what you exhale and it is what “feeds” plants. Without CO2 there would not be a single blade of grass or a redwood tree, nor would there be the animal life that depends on vegetation; wheat and rice, for example, as food. 

There is not ONE climate computer model that has accurately connected CO2 to climate change. In fact CO2 is at its highest levels in 13,000 years and the earth hasn’t warmed in almost 18 years. 

The fact that CO2 is the least most common gas in the atmosphere seems to be a moot point to global climate change propoents... 

If you believe AL Gores model, all Polar Ice caps should have melted by last year and most costal cities should be underwater. The Earth’s climate is a very complicated system and the scientists haven’t been able to account for all the components to create an accurate model.

It is misleading and just plain incorrect to claim that disasters associated with hurricanes, tornadoes, floods or droughts have increased on climate timescales either in the United States or globally.

A study published in the July 2012 Journal of the American Meteorological Society concluded unequivocally there is no trend of stronger or more frequent storms, asserting:

"We have identified considerable inter-annual variability in the frequency of global hurricane landfalls, but within the resolution of the available data, our evidence does not support the presence of significant long-period global or individual basin linear trends for minor, major, or total hurricanes within the period(s) covered by the available quality data."

The only thing “man-made” about global warming, is the argument that we should all stop thinking because there is a scientific consensus about global warming. There are too many questions still open.
**

And here's my response.

 I'm writing this from my office in the earth sciences department at USC, where I work as a postdoctoral researcher on climate modeling and geoengineering. I have a PhD, and I work on this stuff for a living. I say this not as an appeal to authority (I'm going to back up what I say), but to establish that I very much know what I'm talking about here. I'm not a layperson; this is my job, and I've been researching it for the better part of a decade. Let's go through this point by point.

1. The sea ice extent is a complicated case. The argument is not that global warming causes global cooling. That's obviously idiotic, though due to changes in atmospheric and oceanic circulation patterns, some areas can indeed expect to see record low temperatures. The increase in the ice caps has more to do with slightly elevated temperatures being more conducive to snow accumulation. This sounds just as paradoxical, but it isn't really. The water vapor capacity of air is partially a function of temperature, and (all other things being equal) warmer air is better at holding moisture. The polar regions are cold--really, really cold. In the polar winters, they're generally so cold that they don't hold much moisture at all. This is particularly true in Antarctica, which is significantly colder than the Arctic. It seems strange, but most of the ice shelf in Antarctica has historically been due to accumulated ice rather than snowfall. The ice extent in Antarctica has indeed expanded in recent years, but that's because the slightly warmer temperatures around the southern pole have slightly increased, which has allowed the air to take up far more water vapor than it could before, and winter snowfall has increased. This isn't paradoxical because the Antarctic is still far, far, far below the freezing point of water during the winter months, but the slight increase in temperature has allowed more snow (rather than just ice) to fall and accumulate down there. Moreover, the increase in surface ice is precisely what we'd expect to see if deep water ocean currents were warming, slowly melting ice underwater and bringing very cold water to the surface. The Earth's oceans are very dynamically active, with currents moving not just horizontally but vertically as well. The vertical circulation currents are called the thermohaline, and their stability is integral to aquatic ecosystems. The thermohaline helps "recycle" ocean water, bringing more nutrient rich water up from the deep oceans so life closer to the surface can survive. The disruption of the thermohaline, which is primarily driven by temperature differences, is one of the biggest concerns that many climate scientists have. It's a fairly delicate system, and it's the kind of thing that will not gradually shift, but rather will work well until it suddenly collapses. If that happens, it's going to spell big trouble for everyone.

2. The supposed global warming pause you're alluding to is a myth. The flattened curve that often gets passed around in these discussions is usually a depiction not of temperature, but rather of the first derivative of temperature: the last few years have showed a slowdown in the rate of warming, but average temperatures have continued to increase. Exactly what caused the slowdown isn't completely understood yet (science is hard!), but there are a few things to say. First, remember that climate fluctuations are very long-term movements. The climate changes at the very fastest on an order of decades, not months or even years. Climatology is a study of long-term trends, and we expect to see some fluctuation on a year-by-year basis, even with the very strong change in radiative forcing caused by anthropogenic greenhouse gas emissions (more on that in a moment). In the same way that a freak snowstorm in July (or an unseasonably warm day in February) doesn't signal the onset of a season change, a few years with a warming rate slowdown doesn't signal the end of a decades-long trend. Rather than attending to small fluctuations, we look at the overall trajectory of the system across a relatively long time. There are a lot of neat mathematical tricks that we can use to extract signals like this from the data that don't rely on "well, this graph looks a little flatter to me" style evidence, and the data are unequivocal that warming is not pausing or decreasing. 

The second major point that needs to be made in this discussion is that air surface temperature data only give us a small slice of the entire picture of what's going on with our climate. Part of why climate science is difficult to a degree that (I would argue) is unrivaled in either contemporary or historical science--with the possible exception of cognitive neuroscience--is that a complete understanding of the state of the global climate requires collaboration between experts in what would have previously been considered disparate fields. Oceanography and atmospheric physics, for instance, both require highly specialized knowledge and very different training; they are sciences in their own right. Understanding the climate as whole, though, means that we have to understand what's going on deep underwater, as well as what's going on in the upper atmosphere (and those are just two examples). Water makes a significantly better reservoir for heat than does air (see 1), and there's a lot of water in the oceans. One of the ocean's biggest influences on the global climate comes from its ability to act as a heat reservoir for the atmosphere. This also explains why coastal regions tend to be more temperate than regions of the same latitude, but further inland. When the air is cold, the ocean radiates heat to keep it warm. When the air is warm, the ocean absorbs heat to cool it down. This is why, for instance, Santa Monica and Irvine, CA can have such wildly different temperatures on the same day, despite being only a few dozen miles apart: the ocean acts to moderate the temperatures in Santa Monica. On a global scale, this is important for a few different reasons. First, since the vast majority of the Earth's surface is covered by the oceans, and because ocean water has a relatively low albedo--it absorbs far more sunlight than it reflects--much of the incoming solar energy gets absorbed by the oceans. As the air has warmed up, the oceans have absorbed more of this heat energy, where it is sequestered in the deeper waters via the thermohaline (again, see 1). The reason why warmer temperatures make the oceans absorb more heat is complicated, but it's not terribly important for our purposes here: it's enough to understand that we don't have a complete picture of warming just by considering atmospheric temperatures. All of the evidence indicates that deep water temperatures are rising, and this helps explain the nature of the atmospheric temperature slowdown; the Earth isn't warming less, it's simply warming in different places. As I said before, there's reason to think that this is even more worrying than mere atmospheric warming, since the oceans are in some ways far more delicate than the atmosphere.

3. This is just silly. The worry is not that CO2 is a pollutant in the standard sense (i.e. that it's going to decrease air quality, cause asthma, or suffocate people). The CO2 concentration in the atmosphere is on the order of hundreds of parts per million, which is very, very well within breathable range for humans. Things have to get Apollo 11 levels of bad before we worry about not being able to breathe, and that's not going to happen. The concern is that CO2 is a greenhouse gas. Here's how the greenhouse effect works.

First, it's important to understand that the term “greenhouse effect” is somewhat misleading: the mechanics of the effect bear only a passing resemblance to the mechanics of man-made greenhouses. Artificial greenhouses are kept warmer than the ambient environment primarily through a suppression of convection: that is, the glass in the greenhouse prevents warm air—which is less dense than cold air, and so will tend to rise above it—from rising away from ground level, and thus keeps conditions warmer than they would be otherwise. A similar mechanism is at work when you leave your car parked in the sun on a warm day: the interior heats up, but because the cabin is air-tight (at least on the timescales of interest to you during your trip to the shopping mall or grocery store), the warmer air inside the car and the cooler air outside the car cannot circulate, so the temperature increase can build up over time. The planetary greenhouse effect operates very differently. The layers of the Earth’s atmosphere are not closed systems in this sense, and while convection impediment can play a role in increasing radiative forcing felt on the ground—the fact that cloudy nights are generally warmer than clear nights is partially explained by this effect—it is not the driving factor in keeping the surface of the Earth warm. It has to do with the absorption and emission of radiation.

Different gases have different absorption properties, and so interact differently with various wavelengths of radiation. Radiation of a given wavelength may pass almost unimpeded through relatively thick layers of one gas, but be almost totally absorbed by even small amounts of another gas. This is the source of the greenhouse effect: the composition of the atmosphere directly affects how much radiation (and of which wavelengths) is able to escape to space. The wavelength of the energy radiated by an object depends on its absolute temperature, and that this means that the temperature of the Earth depends on the composition of the atmosphere. 

Molecules of different gases have different molecular structures, which (among other things) affects their size and chemical properties. As incoming radiation passes through the atmosphere, it strikes a (quite large) number of different molecules. In some cases, the molecule will absorb a few of the photons (quanta of energy for electromagnetic radiation) as the radiation passes through, which can push some of the electrons in the molecule into an “excited” state. This can be thought of as the electron moving into an orbit at a greater distance from the nucleus, though it is more accurate to simply say that the electron is more energetic. This new excited state is unstable, though, which means that the electron will (eventually) “calm down,” returning to its previous ground state. Because energy is conserved throughout this process, the molecule must re-emit the energy it absorbed during the excitation, which it does in the form of more E/M radiation, which might be of different wavelengths than the energy originally absorbed. Effectively, the gas molecule has “stored” some of the radiation’s incoming energy for a time, only to re-radiate it later. Because the incoming solar radiation and the outgoing radiation leaving the Earth are of very different wavelengths, they interact with the gasses in the atmosphere very differently. Most saliently, the atmosphere is nearly transparent with respect to the peak wavelengths of incoming radiation, and nearly opaque (with some exceptions) with respect to the peak wavelengths of outgoing radiation. 

The physics behind this is very well understood, and not at all controversial. The deeper explanation appeals to quantum mechanical features of gas molecules, and I can say more about that if you like, but that's not necessary to get the idea. Again, this is not at all controversial. It's basic physics.

4. Much of this is just misinformation--it's simply factually wrong. I'll say more about the points having to do with modeling in a moment. The only thing I'll say here is that while CO2 levels contribute to warming, they're not the only thing that does so. Demonstrating that CO2 levels were different in the past and that temperatures were different doesn't show anything interesting at all, as there are many factors (the scientists call them "forcings") that contribute to global temperature. CO2, as you likely know, isn't even the strongest greenhouse gas. It simply makes a convenient standardized measurement.

5. CO2 is not the least abundant gas in the atmosphere. Not even close. Other than that, I'm not sure what your point is here.

6. This is the most interesting point in this whole discussion, in my opinion. The reliability of computer modeling in complex systems is my specialty, and what you're saying is (at best) a half truth. Here are the senses in which what you said is true: no single computer model gets everything right, the global climate is a monstrously complex system, and we're still working on improving our models.

That said, none of this implies that the models don't do well, or that we're ignorant. It's true that individual models have variable degrees of success in predicting the evolution of the global climate. However, we don't make predictions based on the output of single models for this very reason--hell, individual models can differ in their predictions from model run to model run. Rather, we use a technique called "statistical ensemble modeling" that takes this variability into account, and even capitalizes it. Rather than looking at the output of a single model run (or family of model runs), we look at the output of a wide variety of different models parameterized with different initial conditions and assumptions about how things work. The output of these different models is then "averaged" (it's a little more complicated than regular averaging, but that's basically what's going on) to provide a meta-model prediction. These ensembles of models do extraordinarily well in predicting how things are going to change, and are almost mind-bogglingly computationally complex. They're also built from very uncontroversial equations of motion drawn from radiative physics and fluid mechanics. The best contemporary models--coupled global circulation models (CGCMs)--are literally simulations of the world's climate. CGCMs break the planet down into a three dimensional grid composed of cells, each of which is (in the best CGCMs) a few kilometers on a side. The computer runs some physics equations that describe what's going on with each cell, and then step the time forward a few seconds, use the last state of the cell, and run the equations again. The output is marvelously precise, and reproduces past climate changes perfectly. Are there still improvements to be made? Absolutely. Shrinking the grid size to below 1 KM is a big goal, because that will give us the kind of resolution that will allow us to model even individual clouds accurately. Science is a work in progress, but our models are remarkably reliable, and comparing the observed data to the ensemble prediction results in a very, very good match.

7. The trick going on here is that claims about a great scientific controversy survey anyone working in any science (and often engineering). Those aren't the people worth paying attention to: scientists specializing in climate science are. The opinion of someone working outside the field is worth little more than the opinion of an educated layperson.

The most recent example of this kind of sleight of hand that comes to mind was the recent article in Forbes claiming that peer reviewed survey found that the majority of scientists were skeptics about global warming (http://www.forbes.com/sites/jamestaylor/2013/02/13/peer-reviewed-survey-finds-majority-of-scientists-skeptical-of-global-warming-crisis/). The catch is that if you read the actual study, their definition of "scientist" includes anyone with a PhD or master's degree in "geosciences or geoengineering" working in any field of science or engineering, and living in Alberta, Canada. Why does that matter? Well, because (as the paper itself notes): 

"And the petroleum industry – through oil and gas companies, related industrial services, and consulting services – is the largest employer, either directly or indirectly, of professional engineers and geoscientists in Alberta." The vast majority of those surveyed were petroleum engineers employed by oil companies, not climate scientists doing peer reviewed research. My point is not that there's some kind of conspiracy going on, but just that it's very easy to manipulate data by this kind of study design. You need to be careful and dig deeply when looking at this stuff.

The meta-studies you described are actually far more reliable than simple surveys, as they let us look at what research is actually being published in reputable journals by specialists. All those meta-studies support the position that there's a strong consensus about anthropogenic causes of global warming.

8. Moore is simply wrong about the lack of evidence. Also, his full claim was that humans are not solely responsible for global warming, and he suggested that increased solar activity was a more likely culprit. Even he has had to back off this claim, though, as solar activity has been far below average during the period when warming has been sharpest.

How do we know that humans are contributing to global warming? There are lots of ways. For example, not all CO2 is created equal. The process of combusting fossil fuels that's characteristic of most anthropogenic CO2 release results in a chemically distinctive CO2 molecule that looks different from those released by other causes. We can measure the CO2 content of the atmosphere, and then look at what percentage of the CO2 increase is accounted for by the anthropogenic CO2. When we make this measurement, it turns out that the vast majority of CO2 increase is coming from people, which means that we are significant drivers of the greenhouse effect. If you're skeptical about the greenhouse effect, refer to (3). 

Does this prove that we're the sole cause? Of course not. The climate is (again) very complex, and there are lots of factors at play. The fact that we may not bear sole responsibility for warming, though, doesn't exonerate from being responsible for the role we are playing, and if there are non-anthropogenic forces at work in warming the climate, that's only more reason for us to be cautious: it suggests that even if we stop contributing, warming might continue (albeit at a much slower rate) anyway. This should make us more concerned, not less concerned.

Another good indicator comes from the computer models, which can (and have) been run to generate predictions about what the climate would look like without anthropogenic forcings. The projections don't match observed data at all, whereas predictions that include anthropogenic forcings match observation quite well.

9. There was some talk in the mid-20th century about global cooling. Most of it had to do with concern over the increasing release of sulfur dioxide into the atmosphere; Carl Sagan was a notable figure who worried about this. SO2 is a naturally-occurring (though tiny) constituent of the atmosphere--and also the byproduct of a number of important industrial processes. It’s also released in very large quantities during volcanic eruptions. 

SO2 is what climate scientists call an aerosol; soot is another prominent aerosol. Contrary to many other cases, the technical use of this word isn’t significantly different from the colloquial use: aerosols are small particulates that get suspended in the air (think of everyday aerosols, like spray paint or nasal spray, which propel tiny particles of liquid suspended in a gas). Aerosols are significant for the global climate because when they’re present in significant amounts, they exert a quite strong cooling influence on the global temperature. They do this in two distinct but related ways. The first is by modifying the amount of incoming light that simply “bounces off” the atmosphere without ever having a chance to make it very far in (climate scientists call the amount of light that bounces off in this way the albedo of the planet). The tiny particles in aerosols act as what we might think of as “microshades,” helping to shield the planet from sunlight. Aerosol particles also act as nuclei for water vapor to collect around, thus contributing to the formation of cloud cover, similarly cooling the planet. These effects are why, for instance, large volcanic eruptions can drop the average global temperature by significant (in the scheme of things) amounts. Anthropogenic emissions of aerosols skyrocketed (so to speak) in the mid-20th century:

While the concerns about global cooling--both from aerosols and from nuclear winter--were quickly eclipsed by other concerns (and never really represented a scientific consensus in the first place), they represent an important milestone for this discussion: the very public discussion surrounding nuclear war and SO2’s effect on climate was, for many average citizens, the first time they were exposed to the idea that human behavior might shape climate trends in a significant, long-term, irreversible way. It represented one of the first instances of a dawning realization that would come to dominate much of the public discussion of climate for the next decades: human civilization has gotten so big that we’re now acting on a global scale.

Overall, though, the idea that there was a scientific consensus about global cooling in the 70s is largely a myth. There were a small number of studies that considered the possibility, but we quickly realized that the greenhouse effect was a more dominant feature in the Earth's climate. There's some talk these days about utilizing aerosols as a geoengineering solution to slow warming down by injecting certain aerosols into the atmosphere, but that's another discussion.

10. The key phrase there is "on climate timescales." Remember, climate change operates on a scale of decades. We simply don't have the data yet to be able to differentiate a signal from noise--to be able to tell climate change caused shifts in droughts from the background noise of normal climate fluctuation (see 2). It's clear that some areas of the world are experiencing unusual droughts, but we just can't tell yet if that's part of the normal variability. The model predictions aren't good, though.

It's also worth pointing out that some areas may see an increase in rainfall as a result of climate change, while others may see a decrease. This isn't paradoxical, but it could be a big problem. Some major agricultural powerhouses (especially in Africa) operate on a very thin margin of rain, and even a very small change could be disastrous. Similarly, a small increase in annual rainfall in other areas could have significant consequences for human life, as things like levees and dikes are overwhelmed by the increase.

11. I can't speak to this one. I'm not a biologist or an ecologist.

12. It's true that no change in hurricane intensity has been detected, but (to my knowledge) there was never a suggestion in the scientific literature that it would be.___

"Fuck John Searle!"

Whatever would Barbie do!  Her homework was due in an hour!

This is a really neat visualization of carbon dioxide emission and flows over the course of a calendar year. The transition between seasons is probably the most striking part: as winter turns to spring, all the blooming plants rapidly (and impressively) scrub out a lot of the collected CO2 in the atmosphere. That's part of why deforestation is worrying to a degree that goes beyond the actual CO2 released in the process of turning forests into farmland (or cities).

New computer model provides a new portrait of carbon dioxide

Read more: http://1.usa.gov/1yNeIKb

An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe.

Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons.

The carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office.

The visualization is a product of a simulation called a “Nature Run.” The Nature Run ingests real data on atmospheric conditions and the emission of greenhouse gases and both natural and man-made particulates. The model is then left to run on its own and simulate the natural behavior of the Earth’s atmosphere. This Nature Run simulates January 2006 through December 2006.___This is a really neat visualization of carbon dioxide emission and flows over the course of a calendar year.

There's an elitist thread that runs through some discussions of Burning Man that I absolutely despise.  The original post here isn't a strong example of that (though it's in there), but a lot of comments are.  Someone suggested that given Burning Man's exposure here, we ought to start requiring "references" before people are allowed to buy a ticket, or require them to attend a number of regional events first (so that we can avoid "tourists").  The poster said "just like the Rangers do."  I wrote a reply:

There’s something of a vetting process (training, both off-playa and on-playa) to make sure you’re serious and responsible, but that’s about it. Anyone is welcome to Ranger. Radical inclusion.

I understand your concern–and the concerns expressed by the OP–about virgins not understanding the principles, coming as tourists, &c.–but I don’t think the answer is requiring endorsement from an existing Burner, nor do I think that we should require attendance at regional events. There are two big reasons for that.

First, attending regional burns is not always an option for everyone. Whether you live in an area that isn’t home to a near-by regional, spend all your annual vacation on Burning Man itself, can’t afford a second extended camping trip every year, or simply aren’t interested in attending smaller off-playa events, many people who would love Burning Man and make great community members would be excluded by that kind of requirement. I’ve been attending Burning Man for 10 years, I’m a Ranger, and I’ve never been to a regional burn. That’s something I’d like to change, but right now it’s just not an option (for a combination of the reasons I listed above).

Second, I think turning Burning Man into an (even more) exclusive “country club” kind of group goes strongly against many of the 10 Principles. We want to be inclusive. We want to be participatory. We want to welcome anyone and everyone who wants to be a part of the community with open, dusty arms. We were all Virgins once, and many of us attended Burning Man for the first time on a whim. Many of us were surprised by what we found. BRC is never what you expect, no matter how many times you attend–that’s part of what makes it so wonderful. A lot of people will undoubtedly attend the event based on The Simpsons’ portrayal of it. Some of them will be pleasantly surprised at what they find; others won’t be. Some will come back; others won’t. Some will be immediate participants; others will need some coaxing and help. All of these are OK.

Decreasing the numbers of tourists isn’t about weeding people out before the get through the gate. It’s about giving people who might otherwise be tourists more opportunities to be participants, and helping them find a place in our community. It’s about sharing the experience with them, showing them what Burning Man means to us, and encouraging them to help craft the experience for both themselves and everyone else. I haven’t seen The Simpsons episode yet, but I’m delighted that the mainstream default world is being exposed to Burning Man, even if it isn’t a perfect representation of BRC (what the hell would that even look like?). The more the merrier."

Yikes.

The New York Times has published an unredacted version of the famous “suicide letter” from the FBI to Dr. Martin Luther King, Jr. The letter, recently discovered by historian and professor Beverly Gage, is a disturbing document. But it’s also something that everyone in the United States should read, because it demonstrates exactly what lengths the intelligence community is willing to go to—and what happens when they take the fruits of the surveillance they’ve done and unleash it on a target.___Yikes.

I don't think I agree with the claims about the arrow of time, but there's a novel definition of complexity buried in here that I think is very interesting.  They're basically taking a ratio of the overall size of a system and how close the closest parts of the system are to one another and calling that the complexity.  The idea is to give an objective measure of the inhomogeneity/differentiation of the system.  I think this is on the right track.  

They take care to make it a dimensionless quantity by eliminating scale from all the equations they use to derive the quantity, but I'm not convinced that's the right move.  Functional differentiation might well not be a scale free concept, but rather depend deeply on the structure behind the interactions of this clustering behavior across multiple scales.  I'm still delighted to see this move being made, though.

Toward a post-carbon world

Big news!   European leaders have signed a deal obliging the EU to cut greenhouse gases by at least 40% by 2030, relative to the 1990 level of emissions.  They'd already agreed to cut them 20% by 2020, and they're close to meeting that goal already. 

The president of the EU Council said:

"It was not easy, not at all, but we managed to reach a fair decision. It sets Europe on an ambitious yet cost effective climate and energy path. Climate change is one of the biggest challenges of mankind. Ultimately this is about survival."

This is great.  And there's some self-interest here, too.  The EU plans to make money in the long term by getting ahead of other countries on implementing technologies that reduce carbon emissions.  If they lead by example, it increases the chance that others will follow.

This is great.  And there's some self-interest here, too.  The EU plans to make money in the long term by getting ahead of other countries on implementing technologies that reduce carbon emissions.  If they lead by example, it increases the chance that others will follow.

As well as the greenhouse gas pact, two 27% targets were agreed - for renewable energy market share and increase in energy efficiency. But the renewable energy agreement is binding only on the EU as a whole, not on particular nations, raising tricky issues. And the energy efficiency target is optional.

The reason?  Its seems some of the poorer nations raised objections: Portugal, Poland, and... umm... Britain?

Apparently the British Prime Minister David Cameron is "keen to minimise any perceived loss of UK sovereignty over energy policy." He tried to cut the energy efficiency target to 25%, but he accepted 27% as long as it was not binding on Britain.  So, now it's not binding on any nation, though somehow it's supposedly binding on the EU as a whole.

Poland relies a lot on coal, and it managed to get concessions that will allow it to get hundreds of millions of euros to modernise its coal-fired power plants. Of eight EU nations eligible for these subsidies, Poland will get 60% of the total up until 2019.

“It’s scandalous,” said Julia Michalak, a spokeswoman for Climate Action Network Europe. “A continuation of free emission permits for Poland’s coal-reliant energy system would be a grave mistake. Leaders who came to Brussels to agree new historic climate goals, are actually discussing whether to hand out money to Europe’s dirtiest power plants.”

But still: we're seeing progress. 

I got a lot of this material from here:

I'm leaving early Thursday morning to participate in this conference on climate modeling at the University of Western Ontario.  I'll be giving a talk called "Multi-Scale Modeling and Emergent Constraints in Climate Science."  Here's the abstract:

"The global climate is a paradigmatic complex system, and so exhibits interesting behavioral regularities at many different spatio­temporal scales. Moreover, these patterns are mutually constraining: the presence of a stable behavioral regularity at one scale can influence the structure of stable behavioral regularities at other scales. This structure of interscale constraints makes the construction of holistic climate models an unusually daunting scientific challenge.

This structure of interscale constraints makes the construction of holistic climate models an unusually daunting scientific challenge. In this talk , I describe some of the novel conceptual and methodological challenges associated with modeling the behavior of complex systems, and consider how those challenges bear on the debate about pluralism in climate models. I argue that the burgeoning pluralism of climate models is a natural consequence of the global climate’s considerable complexity, and ought to be embraced as a boon to our attempt to accurately predict the future of Earth’s climate."

I'm pleased to be able to announce that a group of people finally recognized the innovative nature of the attention economy stuff that +Daniel Estrada has been working on for a decade. Today, an Israeli company announcing a new kind of network that is the apotheosis of distributed currency and social networking. Dan's been quietly working with these guys for months to build this, and it's finally here.

Ok I read the original paper. This was an independent lab doing the review. It's actually very straightforward, and doesn't have any physics beyond pretty basic thermodynamics, fluid dynamics, and my mechanics. Part of the reason that's interesting is that it points to the fact that these people have absolutely no idea what they have on their hands. All of what we know about nuclear physics says that this device should not be able to do what it appears to be doing.

So here's what it appears to be doing: producing more heat (lots more--an order of magnitude more) than should be possible if all that's going on inside the device is a chemical reaction, and doing it with the kind of energy input that you could get out of a plug in your house (as opposed to the kind of energy input you get out of the gravity inside the sun).

Any kind of combustion--from burning gasoline, to coal, to firewood--is a sort of chemical reaction. There's a hard limit on how much energy a reaction like that can put out; it has to do with how much energy is stored in the bonds of the molecules that make up the thing being burned, how hard it is to break those bonds, and how completely they break. That's why something like butane burns hotter than pine wood: butane gas molecules are just 3 carbon atoms and a bunch of hydrogen atoms. The bonds break fast and well, and release lots of energy when they go. 

Chemical reactions can only do so much, though, because they can't change things at the atomic level--only the molecular level. The amount of energy stored in the atomic bonds of a material is many, many times greater than the amount of energy stored in its molecular bonds. Nuclear power produces so much energy because rather than combusting its fuel, it changes its atomic structure. When you either break an atom apart (fission, like in a nuclear power plant) or smash two atoms together to make a bigger atom (fusion, like in stars), some of the energy that was stored in the bonds keeping the atom together gets shot out.

This experiment was set up to see how much energy the device radiated as heat. Because energy is conserved and has to come from somewhere, any heat energy that the reactor gives off that's over and above the energy they put into it has to come from some kind of reaction. They found that the reactor put out heat in quantities that were between 10 and 100 times as much as they could possibly had gotten if they'd simply burned the fuel source. The only other possible source for that energy that we know about is a nuclear reaction. 

Moreover, they compared the relative proportions off different isotopes in the fuel before and after running the device. They found that new elements had formed while the device ran, which also indicates that something nuclear took place. 

Weirdly, though, they never saw any neutrons, gamma radiation, alpha radiation or other nuclear byproducts appear while the device ran; it seems to have emmitted heat almost exclusively. Every nuclear reaction we know of emits radiation, so that's really puzzling. Even the fuel byproducts were devoid of radioactivity. 

The authors of the paper are quite open about the fact that they're at a complete loss to explain this. The reactor seems to work, but not only do they not know why, there doesn't even seem to be a possible explanation given our current physical theory. 

This doesn't mean that this thing has broken the laws of physics. Some sort of experimental or methodological design oversight (or very clever fraud) is still the more likely explanation. The out-of-the-blue design of a totally revolutionary invention that overturns the laws of physics as we know them happens, well, basically never. It's not impossible that this thing is something totally new--the kind of breakthrough that will change our civilization forever--but we shouldn't jump to conclusions; good science is conservative. There are a lot of questions that need answers still (we don't know the internal structure of the reactor even yet), and while this is an exciting and intriguing result, there's a lot of work still to do.___
