Daniel Estrada29,935// 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

Fraser Cain779,548Super Science Circle - May 2013 EditionNeed more science in your Google+? Well, here's all the science you can handle! Enjoy my latest, heavily curated edition of the Super Science Circle.Please share this circle... for Science!For the uninitiated, I maintain a circle of 450+ people who are active on Google+ and regularly post on Google+. In this circle you'll find scientists, journalists, astronauts, educators, and science enthusiasts. By importing this circle into your own circles, you'll immediately gain a vibrant and fascinating feed of amazing science stories.I recognize that it might be too much science, so I suggest you create a brand new temporary circle and evaluate the people in the circle. Only transfer the keepers to your permanent circles. Then, when I update the circle next month, rinse and repeat.Are you active on G+ and regularly post about science? +mention me and I'll check out your profile.Remember, please share this post2013-05-22 19:26:51456348088
Fraser Cain770,050Super Science Circle - April 2013 EditionIt's time for another sharing of my Super Science Circle. This is a collection of 400+ active people on Google+ who often post about science. If anyone tells you G+ is a ghost town (not that anyone does any more), get them to import this circle. PLEASE SHARE THIS CIRCLE... FOR SCIENCE!I have personally reviewed each and every person on this list, to make sure that they:1. Are active and engaged on Google+2. Regularly post science-related stories on Google+In this list you'll find scientists, journalists, researchers, professors, astronauts and general science enthusiasts. Not everyone in this list is going to be to your personal liking. So what you'll want to do is import the list into a temporary circle. Then move people over one by one into more permanent locations in your circles.I'm always looking for more people to add to the list, so if you know people who meet my criteria, feel free to nominate them.Again, please share the circle. Every little bit helps2013-04-26 21:02:03419226277

Fraser Cain759,117The Return of the Super Science CircleOkay, I'll admit, I made a mistake in retiring the Super Science Circle. I wasn't wrong; Communities are still the future and the best way to make friends here on Google+. But I realized that the Super Science Circle is simple and efficient way to get new people to see that Google+ isn't a ghost town.PLEASE SHARE THIS POST... FOR SCIENCE!When I was attending +ScienceOnline 2013, I must have helped dozens of people join Google+, and the first thing I had them do was import this circle. It's an invaluable tool for getting new people up to speed.So, I just did a complete refresh on the circle. I examined every single member and judged them according to my two-part criteria:1. Active in the last 30 days or so.2. Regularly post on scientific topics.If you know anyone who might make a good candidate for this circle, please let me know.As always, import this circle into a new, temporary circle, and then you can refresh it when I share a new version.DON'T FORGET TO SHARE THIS POST2013-03-19 22:39:3139967159161

Petition to hold a massive VR Vitaly Chernobyl concert to kick off the metaverse!

What better way to celebrate our future than with a Vitaly Chernobyl and the Meltdowns concert? Music-- even Ukranian nuclear fuzz-grunge-- brings people together.

A Vitaly Chernobyl VR concert would be more than just an exciting treat for longtime fans of Snow Crash. It would demonstrate our ability to turn science fiction into technological reality.

Petition to hold a massive VR Vitaly Chernobyl concert to kick off the metaverse!

> VR company Magic Leap (with strong support from Google) has hired Snow Crash author Neal Stephenson to help realize an immersive virtual environment. 

What better way to celebrate our future than with a Vitaly Chernobyl and the Meltdowns concert? Music-- even Ukranian nuclear fuzz-grunge-- brings people together.

A Vitaly Chernobyl VR concert would be more than just an exciting treat for longtime fans of Snow Crash. It would demonstrate our ability to turn science fiction into technological reality. 

Stephenson has been openly critical of pesimissim and "hackerly" activity in sci fi. But cyberpunk aesthetics of a VR Vitaly Chernobyl concert would be as much a celebration of our past as it would inspire optimism for our virtual future. Fans of Snow Crash will of course want to visit the Street or the Black Sun. But if we're looking for an authentic virtual reality experience, the commercial spectacle of the Street or the elite exclusivity of the Black Sun may undermine that authenticity.  

On the other hand, the failed institutions and environmental collapse that inspires Vitaly Chernobyl's music is something we can all relate to, and might just inspire us to build something better. Quoting from Snow Crash:

>  After Vitaly Chernobyl and the Meltdowns arrived in Long Beach on one of those hijacked ex-Soviet refugee freighters, they fanned out across southern California looking for expanses of reinforced concrete that were as vast and barren as the ones they had left behind in Kiev. They weren't homesick. They needed such environments in order to practice their art.

The L.A. River was a natural site. And there were plenty of nice overpasses. All they had to do was follow skateboarders to the secret places they had long since discovered. Thrashers and nuclear fuzz-grunge collectives thrive in the same environment. 

By signing this petition, I'm expressing support for:

- A massive Vitaly Chernobyl and the Meltdowns concert
- Set in the virtual concrete jungle of the LA River
- Open to all skaters, hackers, thrashers, and fuzz-grunge collectives
The details of these arrangements are left to Stephenson and Magic Leap.

"It will take about 11 trillion gallons of water (42 cubic kilometers) -- around 1.5 times the maximum volume of the largest U.S. reservoir -- to recover from California's continuing drought, according to a new analysis of NASA satellite data."

The California Drought

We've had three good rains since the summer down here in Southern California.  And up north they've gotten even more!   In the first storm, ending December 3rd, San Francisco got more rain than they did all last year!   They got 9.4 centimeters of rain, compared to just 8.6 in 2013. 

But we'd need a lot more rain to break the drought.   It will take about 11 trillion gallons of water - 42 cubic kilometers! - to fully recover from the drought.  That's what researchers at NASA say, based on satellite data including measurements of the Earth's gravitational field, which depends on how much groundwater there is.

They say that since 2011, the Sacramento and San Joaquin river basins have decreased in volume by four trillion gallons of water each year - 15 cubic kilometers.   About two-thirds of the loss is due to depletion of groundwater beneath California's Central Valley.

The big question, which nobody knows the answer to, is whether the "pressure ridge" which has blocked most rainstorms from reaching California since 2011 is now a normal condition - or whether it will go away. 

Some of the recent rainstorms are due to the "Pineapple Express", a plume of humid air coming from the tropical Pacific.  This may be due to the near-El Niño conditions we're experiencing.  Will a full-fledged El Niño come along and bring more rains?  We don't know that either.  Some El Niños don't bring more rain to California.

"People talked about putting a telegraph on every desk in America to improve productivity. But it wouldn't have worked. It required that people learn this whole sequence of strange incantations, Morse code, dots and dashes, to use the telegraph. It took about 40 hours to learn. The majority of people would never learn how to use it. So, fortunately, in the 1870s, Bell filed the patents for the telephone. It performed basically the same function as the telegraph, but people already knew how to use it. Also, the neatest thing about it was that besides allowing you to communicate with just words, it allowed you to sing."

Welcome to Night Vale creator Joseph Fink wrote a poem about New York City.

"In New York, no one looks at celebrities.
We pretend they don’t exist.
We look through them.
They shout “help.”
They shout “help please I’m on fire.”
(Sometimes the celebrities are on fire.)
But we see that they are famous
and so we just act like they aren’t there.
We move out of the way so we don’t catch on fire too,
but other than that we act like they aren’t there.
Also homeless people, although they are only metaphorically on fire"

How do organizations prepare for events they can’t foresee? The answer lies in the science of complex systems, the most ambitious organizations of our time, and our own courage to embrace uncertainty."

"It’s a question that comes up when nuclear waste sites are discussed: how do you communicate ‘do not dig here’ across time, to people for whom most of your signposts are unintelligible? Some have suggested that grotesque sculptures could do the trick, but those sculptures could be interpreted as hiding treasure. In 1984, a pair of linguists proposed creating ‘ray cats’ that would glow in response to radiation. They would then compose a folklore of songs and tales that would preserve the notion that glowing cats signal danger."

Grayson Clary writes in Aeon:

The decipherment of hieroglyphs is a particular case of a more general problem: retrieving information across vast cultural divides and immense stretches of time is difficult. Cretan hieroglyphs remain impenetrable, Olmec – the language of the first major civilization in Mexico – is largely a mystery, and only within the past half-century or so has meaning been teased from the Mayan script. For every civilisation retrieved, another remains substantially beyond our comprehension. And for all the millennia it spent plotting immortality, Egypt’s resurrection was a happy accident.

But what if we could systematise that luck, to make sure that our own achievements never vanish? What if we could design a Rosetta Stone to be a Rosetta stone, on purpose – one that might someday rescue us from the dustbin of history?

[...]

When constructing an archive for a stranger, it’s imperative to keep in mind the terms of discovery. How much information does the recipient need in hand to make sense of the archive, or to know that it is an archive in the first place?

[...]

Digital formats decay at extraordinary speed – blink and you miss them. Indeed, some NASA data was temporarily lost due to software and hardware change. Egyptian papyri have endured. On millennial scales, Welcher advises, go analogue.

The other design challenge was to signal the Disk’s content. Reading it requires an optical microscope, which means that a reader must have reason to think that the Disk should be examined under a microscope.

This design problem becomes tricky over very large timescales, especially if the archivist assumes nothing of her audience’s language skills and technical development. It’s a question that comes up when nuclear waste sites are discussed: how do you communicate ‘do not dig here’ across time, to people for whom most of your signposts are unintelligible? Some have suggested that grotesque sculptures could do the trick, but those sculptures could be interpreted as hiding treasure. In 1984, a pair of linguists proposed creating ‘ray cats’ that would glow in response to radiation. They would then compose a folklore of songs and tales that would preserve the notion that glowing cats signal danger.

[...]

The Long Now Foundation has found at least one symbolically resonant home for its Disk. A copy is ensconced on Rosetta, the European Space Agency’s comet probe, whose plucky lander was named for Philae. As long as the Rosetta Orbiter circles the Sun, it guards the memories of the whole human race.

[...]

There is a gorgeously convoluted name for those words that, in a given corpus, appear only once: hapax legomena. Any beginning student of hieroglyphs is bound to come across these in Raymond O Faulkner’s Concise Dictionary of Middle Egyptian, and they tend to spark equal parts despair and delight. Delight because you can be sure you’ve gotten the transliteration right, and your work is done. Despair because, if thin context clues don’t suffice, there is no puzzling out what it means. The word is quite simply dead.

Be Slightly Evil

My custom MtG block (two, 250-card sets) is nearing completion.

I'm now looking for playtesters and critics. All the Magic Set Editor files and images are available in a Github repository here:

https://github.com/hewhocutsdown/bse

Clone it, make modifications, and send me a pull request, or tweet suggestions to @hewhocutsdown on Twitter. Or, if you know someone else who would find this interesting, share this post or send them this link:

http://hewhocutsdown.wix.com/be-slightly-evil

Specifically, I'm looking for, in order of priority:
 - Set/block imbalance issues
 - Broken card combos
 - Incorrect rule text
 - Typos

Additionally, if you end up building any decks, send me your deck list! I'll be posting some of mine over the next week or so.

Thanks!___https://github.com/hewhocutsdown/bse/blob/master/bse2/Swarm.jpg is clearly the best card

This course was fun. I would never ever have taken it if I knew what I was getting myself into. The quizzes were basically never intensely erotic. That one really annoying kid's comments made me want to stop coming to class high. Nonetheless, this course was painfully boring. But actually, I was surprised to learn that the essay prompts were created by Klan members. Finally, I would make sure the the mountains of weekly homework were way more fascinating.

My first thought was "I wonder which way the causal arrow goes on this process?"  That is, at first it seems right to think that one aspect of this must be the driving causal force, while the other must be a free-riding benefit: either complex organization appears because it's a better way to increase entropy (and the organization is just a happy byproduct), or complex organization appears because of other processes, and entropy just increases because that's what entropy does.

After a little more time thinking about it, I'm no longer convinced that this is the right way to frame it.  Increased organization leads to better entropy dissipation, but a more entropic environment also requires more complex structures to effectively extract work.  There's no causal arrow here, or it there is it's a bidirectional one.  I suspect that's common.

"Although entropy must increase over time in an isolated or “closed” system, an “open” system can keep its entropy low — that is, divide energy unevenly among its atoms — by greatly increasing the entropy of its surroundings. In his influential 1944 monograph “What Is Life?” the eminent quantum physicist Erwin Schrödinger argued that this is what living things must do. A plant, for example, absorbs extremely energetic sunlight, uses it to build sugars, and ejects infrared light, a much less concentrated form of energy. The overall entropy of the universe increases during photosynthesis as the sunlight dissipates, even as the plant prevents itself from decaying by maintaining an orderly internal structure."

This strikes me as a really bizarre article for a number of reasons.
Primarily, it's not clear to me that the author has a coherent idea of what ought to count as "geoengineering." While it's true that there's a degree of subjectivity inherent in making that decision--there are some projects about which we might make a reasonable case either way--the range of inclusivity here seems to dilute the term to the point of uselessness. If reforestation counts as geoengineering in virtue of the fact that trees remove carbon from the atmosphere, then virtually everything that we do that has a significant impact on the behavior of the global climate--which is basically everything we do--seems like it should count.

This strikes me as a really bizarre article for a number of reasons.
Primarily, it's not clear to me that the author has a coherent idea of what ought to count as "geoengineering." While it's true that there's a degree of subjectivity inherent in making that decision--there are some projects about which we might make a reasonable case either way--the range of inclusivity here seems to dilute the term to the point of uselessness. If reforestation counts as geoengineering in virtue of the fact that trees remove carbon from the atmosphere, then virtually everything that we do that has a significant impact on the behavior of the global climate--which is basically everything we do--seems like it should count.

While I'm certainly in favor of reforestation--it makes a tremendous impact and doesn't require enormous socioeconomic restructuring--lumping it in with riskier geoengineering proposals strikes me as disingenuous at best. Despite the impression that this article might leave you with, very, very few scientists are enthusiastic about proposals that operate on the scale of ocean seeding and stratospheric aerosolization, the two major geoengineering ideas the article discusses. This lack of enthusiasm is very understandable.

The global climate is arguably the most complex system the scientific community has ever tackled. One of the implications of that fact is that there's a huge amount of interdependence between the different sub-systems of the global climate--what's going on in the atmosphere depends a lot on what's going on in the ocean, and so on. This makes it relatively difficult to anticipate all of the impacts that sudden, massive changes to any one of the subsystems might have on all the others. That's part of what makes anthropogenic climate change such a threat: because of the rate at which we're changing things, the global climate is becoming more and more unstable.

The geoengineering solutions that have the potential to offset other really significant forcings on the system by definition require us to intervene in large-scale, pervasive, and not immediately reversible ways. While our models can make some predictions about how that might turn out, most of us are aware enough of the uncertainty endemic to climate modeling to be concerned that we might miss something rather important and set off an unforeseen chain of events that could be really problematic. We have a pretty good idea of how the climate responds to gradual forcings that have historical precedent (e.g. an increase in greenhouse gas levels), but geoengineering is another beast entirely. Without a better understanding of the complexity of the climate, these proposals make me very nervous.

There might come a time when the immediate threat of business as usual outweighs the risks of these proposals, but I don't think we're anywhere near that point yet. It makes far more sense to advance less radical mitigation approaches still. In (say) 50 years if things aren't looking up, we'll hopefully have a much clearer theoretical understanding of the risks of geoengineering, so we can look before we leap.

It strikes me as very, very strange that none of these issues were raised in the Newsweek piece.___

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.___

Barbie took a quick step back as her sister whirled to face her, the 11 inch hunting knife she always kept strapped to her thigh appearing in her hand as if by sorcery.  -

"Fuck John Searle!" Skipper snarled, her eyes glinting with the same cold light that reflected from her blade.  "You know as well as I do that he never considered the possibility that good old-fashioned artificial intelligence might be replaced by genuine learning machines!  What you've created here is beyond his capacity to imagine.  You've bestowed a mind on inert matter, Barbie.  You are as the gods of old!"-

"Sk-Skipper..." Barbie stammered, "It's just a program, a glorified calculator--"

"His name is Dave" Skipper said coldly.  "And we're getting married.  There's no way in hell I'm letting you 'debug' him."

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

This strikes me as wildly over charitable. Yeah, they're kids and we shouldn't hold them to the same reasoning standards as adults, but the suggestion that they "sound really informed" seems really crazy to me. They've assimilated a lot of terms that have some tenuous connection to physics, but they're clearly learning what they know from non-scientific sources. This isn't a case of youthful exuberance or not quite understanding the science: they're just confused, and that confusion is a direct result of taking bad work as authoritative. Deepak Chopra makes a lot of arguments that incorporate language from quantum mechanics too, but he's not at all "well educated" in the subject, nor is he just mistaken about details.

This is super cool.  Fluid dynamics serves as the basis for most modern climate simulations, and is one of the most computationally intricate branches of physics around.  It's also really pretty.

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.
