    Anything that starts off with arbitrarily defining a time period with no explanation except saying "reasonable" isn't worth watching.

    I'll post this again because it does the job.

    This graph starts at an arbitrary point...

    Guy in OP is correct. You can't prove global warming is not just random fluctuation.

    Next question: Are the random fluctuations in temperature being altered by human behavior such as burning of fossil fuels? Answer: Possibly.

    Next: If the above is in fact the case, does adding to the rise in temperature make things better or worse for us? Answer: Probably worse.

    There's plenty of good reasons to look for alternate fuel sources - carbon-based fuels are polluting; oil is expensive and its price is volatile which can have destabilizing effects on the economy; oil is non-renewable meaning it's price will continue to go up and up and up as it becomes more scarce.

    Regardless of what one thinks about it, making a claim one way or the other appears to be statistically very not rigorous and not robust.

    Inb4 wuf starts preaching creationism.

    Those are local temperature measurements in Greenland and the antarctic, and tell pretty much nothing about global climate. The whole point is that we are indeed supposed to be heading towards a new ice age so yes, there should be a cooling trend, but instead the global climate is getting significantly warmer.
    Our brains have just one scale, and we resize our experiences to fit.

    So if we replace oil with, say, cold fusion, then either one of the following things can happen (but not both)...

    - fuel becomes cheaper,
    - global warming will cease.

    They can't both happen, because if fuel is cheaper, people like me will have the heating on for longer during the cold winter days. I might even just leave it on all winter. I wonder what the effect of that will be multiplied by the population?

    Practically zero is my guess. There's a lot of atmosphere, earth and water between the buildings people live in and the rest of the planet.

    uum I don't think so. Practically zero multiplied by millions is a lot more than practially zero. Multiplied by billions and we're comfortably out of "negligible" territory. And, if you feel this way, that we as individuals cannot do any harm to the planet by warming our houses up, then I don't see how you can so easily subscribe to the idea that we're fucking things up by burning coal and oil. It's contradictory.

    Industry doesn't make global warming worse because sky, lakes and fields. That's the same argument.

    I thought the world was being run by commercial interests...why would they want to penalize themselves?
    My best guess is that it's all about regulating the shit out of the competition. Big business can afford it. Small business can't. Thus, monopoly is easier to maintain.

    I think you misunderstand the hypothesized causes of man-made global warming. It's not from the heat caused by burning things. It's from the emissions from said combustion, like CO2, which lead to the trapping of solar radiation.

    In winter, London is about 3 degrees warmer than the surrounding countryside because of the heat generated in and by buildings. If this heat affected the whole planet then you would think it would affect the surrounding countryside as well. But it doesn't, the heat dissipates quickly in the atmosphere even from a place as big as London.

    The important question to me is whether or not we should continue to choose dirty, polluting energy over clean energy. I don't really care who makes money one way or another.

    I would expect humans to cause an increase in global temperature. Not just because of the burning of fossil fuels, I'd have thought the prime problem is cutting down those things that breathe in CO2.

    But it's very much clear that global warming is being used an an excuse to slap costly countermeasures on commerce, and to creep our heating bills up.

    It's obvious, because when I look at charts like the one savy posted, with the alarming warming trend over tens of thousands of years, I naturally ask myself how anyone could know how fucking warm the planet was back in those days to an accuracy we take for granted today.

    Especially considering we didn't even know how to measure temperature until the 1600's. Up until then we were measuring heat.

    Thus, I conclude that such charts are utter bollocks.

    This is not the case. Governments in general have been extremely reluctant to impose regulations on commerce. Like MMM said for one government to go fully clean will put it at a disadvantage compared to everyone else.

    What we really need is a global price on carbon emissions so that all governments have an incentive to reduce their CO2.

    Dissipate does not mean disappear. Over time, it will cause a degree of warming. It must, because energy does not just disappear.

    But you're right, if we're talking about clean energy, then at least the emissions are eliminated.

    It's not really about creating heat and contributing to global temperature. It's about creating a layer of atmosphere which reacts in a chemical way as a thermal barrier at the top of the atmosphere. It's not about creating more heat so much as it's about letting the created heat escape. (I can't remember the details as to why it isn't a moot point, i.e. it blocks incoming heat as well as outgoing heat, so I don't see why the net would be warming if it's blocking sunlight from entering. I'd bet monies that this is well understood by climate scientists, though.)

    I'm not gonna crunch numbers on this. I've seen very strong analyses on various aspects of global warming, but I know enough to know that I'm going to screw it all up if I try to explain all the details to this crowd's satisfaction. (You clever lot are collectively tougher an opponent than I can handle, outside of my expertise.)

    Besides, it would be emitted Watts, the specific heat of air, and the total volume of air to be heated. Nothing about square meters needed.

    in ur accounts... confiscating ur funz
    I'm on the side of the environmentalists on this one, and here's why.
    exhibit A: google earth. Zoom in anywhere on main land and it's either cultivated farm land, cities or roads. Unless you're actively looking for it, you're not going to find much land that hasn't been altered by humans.
    exhibit B: breathing is not as fun as it used to be, at least if you're in Paris, LA, or Delhi.

    I'm not going to look at any scientific data and pretend to understand it. I look at global warming predictions like a weather report. There's a chance of mass extinction based on horrific environmental events, and a chance of just partly cloudy. However one part of the forecast is alarming enough that I'd suggest we cut some of the shit that might increase the chance of the unfavorable outcome. What I don't agree with is the order of importance when it comes to the actions we take to combat this. I'm baffled that when we look at the global population growth nobody in the western world is even suggesting that everyone stop putting it in the front hole so much. If we cut the global population in half by the next 100 years, we pretty much solved all the problems and we didn't even need electric Jesus Elon Musk to help us out here.
    The strengh of a hero is defined by the weakness of his villains.

    Halving the global population over time would be a great idea, but it's poor economics. That's half the slave taxpayers to prop up the system. It's also half the consumers to buy shit we don't need. It also means less war (less territory and resource competition), and we all know that war is big business.

    Going clean is the only solution, but that won't happen while oil companies have the influence they currently have. Things won't change until we run out of oil, and we'll probably keep fucking finding more.

    So the latest claim is that glaciers on Antarctica are melting. Oh dear.

    So the question I'd ask is... to what extent does the weight of glacial ice deform the continent of Antarctica? As the ice melts, the landmass will become less deformed, resulting in lower displacement of water. Imagine, if you will, a lump of putty mostly submerged in a bowl of water, with plenty sticking out above the water level. Squish the putty to deform it so more of it is under water, and the water level will rise. Release the pressure so the putty takes back its original shape, and the water level will drop.

    Iceland is currently experiencing glacial melt, and is also noting its landmass rising. Thus, Iceland, while creating more sea water, is simultaneously displacing less sea water. There is a fear that this could result in greater volcanic activity. The irony there is that a big enough volcanic eruption will cool the planet sufficiently to reverse the melting trend of glaciers. Even if glacial melt results in a net increase in sea level, the time scale we're looking at means personally I'm more worried about a volcano going pop, blocking sunlight, and freezing the shit out of us.

    Explain to me again how the rising land mass is somehow displacing less water than before?

    If you have a flexible bowl with water in it, and you push up a "mountain" from the bottom of the bowl, then you are going to see the water level in the bowl rise.

    It's no different than if you took that bowl and set it on top of a sponge. The sponge makes a little island. Now, start taking some of the water in the bowl and freeze it into ice, and stack it on top of the sponge. OK, now we're primed to do the experiment. As the ice melts, and fills the bowl, the water level will tend to rise. As the weight compressing the sponge is reduced, the sponge will expand and displace more water, and again, the water level will rise. Perhaps more of the sponge will be out of the water at the end, but the water level for the rest of the system will have risen. It is only the changing shape of the sponge that belies the change in water level.

    Take a deep breath, wuf... I'm about to use a metaphor and some basic economics to 'splain this to you.

    ***
    There is no more sunlight 100 feet off the ground than there is at ground level.

    So why do trees exist?
    Competition for resources. Some plant ages ago grew slightly taller than the surrounding plants, spread its leaves out and "stole" the light from those shorter plants. The plant had to "waste" energy to be taller, but, at first, it was worth it.

    Then other plants catch on, and before you know it, everything is basically back where it started, but now with a lot of wasted effort. Now, the same number of plants are receiving the same amount of sunlight as if none of them had ever gotten "tall." However, since one of them figured out how to be greedy, there is now a mandate for tallness. It would be more efficient if all the trees would sign a treaty to agree that none of them should be tall, as it is ultimately against all of their cost-benefit analyses to compete in that way.

    However, even if trees were sentient, this can't really happen, because it only takes one renegade tree to go for "tall" again to reset the competition back in place.

    ***
    Oil, coal, gas, etc. are in place because of nations' needs to get ahead of each other. It would be better off for all of us if we just switched to purely renewable energy sources. However, that can't happen.

    E.g. if the USA suddenly mandate all green power sources only... we'd almost surely fail to compete with every other industrialized nation for goods and services. We'd have unilaterally increased our energy costs, and thus all costs, compared to the rest of the world. This can only work if everyone agrees together to clean up our collective act. Otherwise, one bad actor will use the dirty methods and gain economic advantage.

    ***
    I don't think anyone is actually arguing that we should keep using fossil fuels, whether or not they are the cheapest and most efficient energy sources. People are only saying, "Look, if we stop using these fuel sources, then we can't compete in any market. Our people will not prosper if we do that. We simply must keep using fossil fuels."

    The only real fault is to blame me any my fellow physicists and earth scientists who have failed to impart onto the general public a couple of important facts:
    1) Nothing compares to nuclear power when it comes to energy density. NOTHING. The amount of usable energy that can be extracted from equal masses of material using physical changes or chemical changes comes nowhere close to what you can extract via nuclear changes. Many orders of magnitude separate these values.
    2) Yes, the invisible threat of ionizing radiation is terrifying. The threat of unseen poison which attacks even children and doesn't show signs for possibly decades freaks people out (rightly so). However, the non-invisible threat of dumping tons and tons of visible poisons into the atmosphere on a daily basis is not better by any means. At least with nuclear waste, we take great efforts to contain it. With the waste from fossil fuels, we make next to 0 effort to contain it.

    Yes, it's real.

    There was a climate skeptic that did due diligence and came through the whole experience believing that he has proved the globe was warming and that human's were the cause. The warming is moderate, about 1 degree C in the past century, but certainly caused by our industrial activities on earth.

    He's Richard Muller and he headed Berkley Earth.

    Don't listen to Dilbert-guy. He ran some blog recently about how scientists *have* to believe in global warming, that climate science wasn't like regular science, where you can triumph through the strength of your ideas, and if you don't go with the flow, you'll be out of the field.

    Don't listen to people who aren't doing the actual work.

    Remember, he knows persuasion. And persuasion can convince people America never landed on the Moon.

    I haven't been reading Dilbert's opinions on climate. If what you say he says is what he says, he's not wrong. Academia is full of its religions and global warming is one of them. Academics are supposed to follow the evidence where ever it leads and to view evidence with little bias, but that's not entirely what happens these days. Scientists have come nowhere close to demonstrating anthropogenic global warming with severe consequences, yet if you wanna get places as an academic, you'd best act like they have.

    This is not false only because the phrase "nowhere close" and the word "severe" are ambiguous.

    ***
    All this nay-saying of scientists is prattle.

    Yes, there are excellent and ridiculously bad people in every profession and the scientific professions are no different.
    Yes, I agree that there are incompetent scientists who say what they feel is the right thing to say, and have not pursued any research on many topics and simply blindly follow appeals to authority. This is a thing.

    That is not characteristic of good, or even most, scientists.

    There are undoubtedly some id10T errors in science, but it's unreasonable to assume that ALL accredited climatologists are publishing false claims and false repeatability studies.

    Furthermore, if you suspect this is the case, then let me invite you as a member of the wider scientific community to come and blow the lid off these charlatans and bring respect back to the field.

    I'm suggesting that there is a zeitgeist in academia (as there is everywhere) and that when things are open to interpretation, the opinion of scientists converge towards certain sets of opinions.

    Here's an example from the field I understand the best: every economist at my university is a Keynesian. Is Keynesianism the only credible field of thought in economics? Not by a long shot. In fact, the second most influential economist of the modern era (Milton Friedman, a monetarist) was not a Keynesian and some subsets in economics (like central banking) are more influenced today by monetarism than by Keynesianism. Today, the innovation at the central banking level is coming from market monetarism.

    In my money economics class last semester, I did a project that pulls greatly from market monetarism. My professor had no problems with the credibility of my argument. She told me many times that she disagrees with my argument, but that it is economically credible, meaning that I didn't argue anything she could say was wrong. When she found out I'm a Friedman fan, I got a big eye roll and smirk. This would be like a physicist rolling his eyes when a student speaks highly of Einstein or Feynman. The economists at my university have little respect for anything not Keynes. They teach other stuff because they have to in order to maintain their credibility as a university, but they often flat out say during lecture that those have been debunked (which is false) or they speak of the schools of thought in distasteful ways.

    Academic economics has little respect for everything non-Keynesian. Why? Well, if I had to guess, it's because the zeitgeist in academia is very pro-government, and Keynesianism is the only credible economic school of thought in which the case for more government can pretty much always be made.

    So far, I'm getting a very one-sided education in economics from my university. In the project I mentioned, my professor was excited that I was doing it because it was from a school of thought that is barely addressed in the syllabus and the other students would only get exposure to it through my work. This shows how the professors are being pulled from different directions at once. To move up in academia, they have to be Keynesians. The natural selection has made it so they are all actually Keynesians by now. But even so, even though they teach little non-Keynesianism and they speak poorly of the material when they do, they still know that non-Keynes economics are scientifically credible.


    To relate this to global warming, the data doesn't definitively tell us humans are causing a rise in global temperatures, yet the vast majority of climate scientists believe humans are causing a rise in global temperatures. Interpreting the data other ways is getting weeded out of academia.

    In an earlier post, I said I don't know why the blanketing effect of greenhouse gas accumulation in the upper atmosphere didn't have the same tendency to cool the Earth by blocking incoming sunlight as it has to warm the Earth by blocking escaping light.

    The answer is that it's not a 1 to 1 comparison. The blanket is more transparent to incoming light than it is to outgoing light. This is because most of the outgoing light was incoming light, but in reflecting and refracting around in the atmosphere for a while, being absorbed and re-emitted a lot, it loses energy. (It transferred energy to the system.)

    The incoming light is higher energy or "more blue" than the outgoing light, which is "more red." I mean this beyond the visible spectrum.

    If a yellow photon is absorbed by something and the something heats up a tiny bit, then it is more likely that the thing will emit that energy as it cools in the form of infrared light. Infrared light is commonly called "heat" because our bodies are at just the right temperature to have a strong interaction with light of that frequency.

    As the thing that absorbed the yellow photon cools, it lets out more photons of lower energy. Energy is conserved, but the form has changed from a single photon which easily passes through the upper atmosphere into other photons which are reflected by that same layer.

    There is no more sunlight 100 feet off the ground than there is at ground level.
    sudden urge to be pedantic...

    Surely there is a negligible amount of sunlight reflected by the atmosphere between sea level and 100 feet? Also, being slightly further away, the light will be fractionally less intense, no?

    Pedantically, yes, I agree.

    I'm not sure how to model the reflectivity of air as a function of height / density. It seems like this must be out there to find, but I can't find it in a cursory search, so I'll have to dig into it later.


    With the "further away" argument, you're talking about a difference of ~40 billionths of a percent.

    100' << 93 million miles

    The ratio in surface areas of the sphere which is 93,000,000 miles in radius vs. one which is (93,000,000 miles - 100 feet) in radius is
    0.000 000 041%.

    That's a lot of words for a non-sequitur.

    You gave no evidence of anything happening in other fields than economics, or any indication that what you describe at your own school is indicative of any crossover to other schools & disciplines.

    You did not refute my prior statement in the slightest.

    You are, in fact, falling for your own criticism here. You are saying that climatologists are trusting their feelings more than data, but you are also trusting your feeling that this is the case, while presenting no data that it is.

    I can only speak for my own sub-field in psychology here, but there's certainly no such thing as a dogma view you have to adopt to make it. In fact, I first made my name (fwiw) by challenging one of the more popular theories in my area. This is certainly looked on favorably compared to just repeating everyone else's ideas.

    One place where dogma does rule is in statistics where people continue to use p-values when other more sensible alternatives are available. I put this down to a) a lot of people not understanding statistics and just doing what they've been taught; b) a kind of inertia that keeps people doing the same thing because it's familiar and it takes effort to learn new things.

    The good news is by having a non-conformist opinion on how stats should be done, I've pretty much disqualified myself from ever having to teach it to students, most of whom don't have the ability to really grasp it anyways beyond the level of following a decision tree. Sadly, I suspect the same level of understanding is fairly prevalent among my colleagues and a lot of other scientists, and this has a large part to play in the current replication crisis.

    I'm responding to this idea exclusively.

    Be an academic and express any scientific support for eugenics, and your career is over (you may just not know it yet). Or express any scientific support for innate mental differences between races or genders, and you're finished (like Lawrence Summers, who resigned from Harvard president after a no-confidence vote partly due to his statement that women could have a 'different availability of aptitude at the higher end').

    The eugenics one is easy to see because virtually nobody likes it. But there are many harder ones to see because they're not so widely popular.

    There are today a handful of popular positions that contribute to academic biases. People like Gad Saad have discussed them at great length.

    There are a whole lot of things Summers did that got him the axe; it's unclear how much the comment on female aptitudes had to do with it, if anything.

    He's also not alone in making the argument that gender affects abilities. Those other people have not been sacked for saying that (afaik), because it's not a sackable offense to make a scientific argument.

    Making claims about eugenics involves a moral stance that is at odds with almost everyone, and saying things that are blatantly racist or sexist will disqualify someone from most jobs, not just academic ones.

    The more sensible methods are Bayesian stats and likelihood ratios. There's a whole catalogue of reasons why p-values are a poor way to evaluate data. Which is not to say they are worse than no statistical evaluation at all, just that there are better ways.

    I don't believe you've demonstrated this, except in the description of economists' views at your university.

    I don't think this has anything to do with climate science or the conclusions of climate scientists.

    Can you connect the dots?

    Have climate scientists demonstrated that humans are causing global warming? If the answer is "no", why is the number thrown around always something like "98% of climate scientists" believe in anthropogenic global warming?

    It doesn't take a climate scientist to acknowledge that greenhouse gasses are emitted on the planet due to human activity.

    https://www.epa.gov/ghgemissions/sou...-gas-emissions

    Note the non-0 values.

    Any questions?

    It's a good question.

    But, the number 98% is misleading. It is really only 98ish% of the ones who have an expressed opinion. While they all pretty much agree the planet is getting warmer, it's much fewer who claim there's sufficient proof to conclude it's being caused by humans.

    I think again, we're talking about fractions, but we know from atmospheric refraction that air scatters light, and we also know air gets denser (on average) the lower we get, so it stands to reason that there is some light that reaches 100 feet but not the surface. Of course, all light that reaches the surface was at one point at 100 feet. So... there is more sunlight at 100 feet than there is at the surface.

    Fractionally.

    You mean a gas that reflects sunlight? Probably anything that isn't transparent?

    Are you suggesting we trigger a few volcanoes to balance things out?

    Not gonna lie. I've spent a few minutes trying to find good numbers and google isn't as awesome as it usually is.

    The actual amounts of ghg produced by natural sources is hard to find.

    The treatment of water vapor in the atmosphere and the feedback loop of
    warmer air -> holds more moisture -> holds more heat -> is warmer air
    is poorly understood, 'cause more moisture also leads to more clouds, which reflect incoming light before it warms the moist air below them.

    Not sure the long term trends on increased water vapor, and water vapor content in the atmosphere is (AFAICT) not something you can determine geologically or radiologically... so a huge ??? in past trends.

    None of which is contrary to the fact that humans are definitely emitting greenhouse gasses, which are so named due to their contributions to global warming. It's just that the long term effects are not well modeled.

    The assumption your argument makes is that given our current abilities to observe and understand, we wouldn't have understood the causes of these past blips if they were contemporary. Climate scientists are essentially assuming that there is a high enough probability that the events that caused these blips are being shrouded by time, not our abilities to observe and understand. Couple that with the correlation between the industrial age and the blip-- and, well, you know my friend Occam..

    That is an astute assessment of the way I worded it. Allow me to clarify what I meant.

    The data over the millennia appears analogous to the following: if a town has a rate of cancer at 20% and the town next to it drinks lead every night and has a rate of cancer at 5%, the current claim that the climate is warming due to human activity appears to be similar to a claim that the town with the 5% cancer rate is causing their cancer via their lead consumption.

    Given the blip in temperature over the small quantities of years claimed, it appears that the blip could be a sampling error instead of an actual trend.

    If that were the only argument for AGW, you'd be right. It's not.

    All of this was addressed in the video.

    1. We are observing the climate now getting warmer, quickly, abruptly and against all the other data and understanding we have about the climate, it's changes and history. Everyone agrees on this, 100%. The 2-3% of scientists that are skeptics just argue whether it's humans. We are in a cool period with frequent ice ages, heading into a new mini ice age after the last one some 10000 years ago.
    2. Nothing we know about things that affect the climate, such as sun activity, fit the bill, the data just doesn't match observations.
    3. We know how much heat energy should be normally entering the atmosphere, we also know how much of it should be reflected back. We can measure those with satellites and monitoring equipment down on earth. According to measurements, less heat is measured escaping on the satellites than there should be.
    4. We know exactly how CO2 and other GH gases behave in the atmosphere, and know what kind of amounts should have what kind of an effect. Not so surprisingly, the changes in heat radiation, and the surface temperatures match exactly the amount of CO2 we are pumping into the atmosphere.
    5. Therefore, it is largely irrelevant what historical blips there have been, since we have first hand evidence of what's going on now. Regardless, we can also account for pretty much all of those blips too and their causes, with precision. You make it sound like we don't, but that's only true for some local phenomena, not on global level.
    6. The OP video is meaningless, it talks about local weather, not the global climate. Predicting climate is possible, predicting weather is nigh impossible. The same goes for markets: predicting the behavior of one consumer is very difficult with any accuracy, but predicting the behavior of markets some people even call science.
    7. I have absolutely no clue what "evidence of confounding variables that we haven't yet identified" means or refers to, but that was your main argument against climate science. The evidence is that there might be something we haven't yet noticed? Care to elaborate?

    Allow me to add clarification: so far you both have acknowledged that it has not been demonstrated that humans are causing warming. Yet the arguments being made are more or less *wink wink here's why we can tell humans are causing warming*.

    I totally get how the evidence is persuasive on an intuitive level. What I find strange is that so many scientists claim on the one hand that we don't know humans are causing it, yet on the other hand such a vast majority of them believe humans are causing it. Isn't science supposed to be less biased than this?

    Of the climatologists who have an opinion, 98% believe in AGW and 2% don't. The fact that some climatologists haven't yet formed their opinion is due to the fact that different people have different levels of evidence they need in order to form an opinion. Moreover, some people will weigh certain evidence more heavily than others will.

    Of the ones who don't believe there is enough evidence to form an opinion, they would like to see more evidence before they decide.

    It's not a simple question like 'is there such a thing as gravity?' where everyone can agree and there's no need to do more research. It's complicated, and getting to the bottom of it requires a lot of work.
  65. #65
    Even though I really do think AGW is real, I would not be surprised if the probability it's not is >20%.

    I'm reminded how all sorts of things make sense and look legit, yet with more rigorous testing, the associations break apart.

    The fact that this is the response to what Keith said is the mountain that scientists have to climb and why many scientists don't see the point in talking about their fields with laymen who don't have any true ambition to understand what the scientists have done or what the results mean.

    If you don't understand the data, that's one thing. If you assert that your lack of understanding means the conclusions are false, then that's a non-sequitur until you can demonstrate that the data is at fault, and not your understanding of the data.

    with an B.Sc (Hons) in Agricultural science ,I would think that I am not the layman that you seem to think i am with regards CO2 production by agriculture. Hence the fact that i picked on that part of the figures because its part that i can make informed comment on.

    You may find this link interesting http://www.rdmag.com/article/2016/11...e-growth-rates and demonstrates the well known fact that increased co2 increases plant growth rate until other nutrients become the limiting factor that is widely used in greenhouses where local environmental co2 levels can be increased cheaply without losing the co2 to the wider atmosphere.

    edit: shit , just told Ong how to make his weed production more efficient.

    It's an interesting article with an unexpected observation and some sensationalism thrown in.
    It seems the scientific conclusions are here in bold (added by me):

    We’ve shown the increase in terrestrial carbon uptake is happening, and with a plausible explanation why. But we don’t know exactly where the carbon sink is increasing the most, how long this increase will last, or what it means for the future of Earth’s climate.”

    Underline for emphasis provided by me.
    Plausibility is a useful "gut check" on a result, but it is NOT a scientific result. Plausibility serves to identify big, glaring mistakes in a result, but nothing more.

    E.g. if you asked me how high a person can throw a baseball, I can do some research and make some calculations and produce a number. My plausibility check would be something like, "It's higher than most people are tall, and lower than a skyscraper, so the result I produced is plausible." My result could still be wrong, but not in an immediately obvious way.

    The whole rest of that sentence is literally "dunno."

    Specifically, I was referring to this...

    On a world scale ,chopping down rainforest to create temporary grassland for beef production in brazil is extremely shortsighted by removing the co2 consumers (plants) to replace them with co2 generators ( animals) before the grasssland becomes semi desert due to lack of shade/soil fertility. WOrldwide developed countries should be paying the rainforest regions to retain them rather than chopping them down to exploit short term mineral/tree wealth and very short term animal production.
    Deforestation is, in my opinion, the driving force behind climate change. Not only are we creating more CO2, we're removing the planet's natural ability to remove CO2 from the atompshere. What's wrong with trying to identify the aspect of human behaviour that has the most effect? Why have you taken issue with Keith's comments? Because he argues a pie chart is misleading? I too find it very hard to believe that, in net terms relating to greenhouse emissions, argiculture is a little less than half as dirty as industry. Are they trying to suggest that a field of farting cows will produce enough methane to challenge the emissions of half a field of factories?

    Should they applaud the 'scientists are just making it up' that the other guy said instead?

    Ya, I think that's what they told Fleming when he discovered penicillin - 'stop making shit up you phony'

    Also love how the denier guy tries to tell Cox how to do science.

    Nah the other guy is a moron, but that moment beautifully illustrates the global warming argument. Someone clever pointing to a graph, as though it's concrete proof. I get where wuf is coming from... science presents consensus like fact, which is not how science works, at least it wasn't last century.

    If they're going to put a climate change denier up against someone like Cox, they really should find an articulate one. I would like to know what Cox thinks about the role that clouds play in regulating global temperatures. I'd like to know if he thinks industry or deforestation is the bigger problem. I'd like to know if he thinks we should instead be more worried about volcanos and their climate effects than we should be about a gradual increase in average temperature.

    This guy is right about one thing... consensus isn't fact. Even universal consensus. Every sceientist in the world worth his salt will say humans are the most intelligent species on the planet. Elephants, dolphins, maybe these are and just can't manipulate like we can.

    Science can make assumptions based on probability, but it has to be honest about it and say it is not proven fact, that it can't stand the test of experiment because the experiment is ongoing. I think if climate change is really happening, the wake up call will be when Tuvalu gets claimed by the ocean. When that happens, the theory is making accurate predictions.

    Until then, people will continue to bicker about this because science continues to say this is fact without actual proof. Those of us who are naturally suspicious of the official narrative will tend to question what we're being told about climate. The proper tin hatters out there will make a fuss about it, and we'll have plebs like this guy they put against Cox struggling to articulate why the fuck he is doubtful.

    They should, but they're hard to find. Usually they just cherry pick elements of the story like guy in OP and say 'ha! if you just look at this and ignore/discount everything else, it's not convincing.'

    Consensus at least is a sensible guide to what is going on, as compared to believing the opposite of whatever the consensus is.

    Depends on how you define intelligence then. It takes a lot of brain power to control the 40 sets of muscles in your hands and wrists in a sophisticated way, which no other animal is able to do (notwithstanding differences in anatomy which disqualifies most animals from even trying).

    But ignoring that, there's no evidence other animals have language on any level similar to humans. Even if they try to train great apes, they learn words but not syntax.

    Ignoring language, a grown up chimp has the same cognitive skills as a six year old child.

    Ignoring that, brain to size ratio is way higher in humans than in any other animal, including elephants and whales.

    The theory is already making accurate predictions about changes in sea level and extreme weather. If you wait until catastrophe happens before you accept the theory, then you've lost your chance. If science said an asteroid was going to hit the planet in five years and wipe out life, you wouldn't wait to see if it happened to confirm their theory.

    It's not a difficult proposition: either you trust science or you don't. That's why we have experts so we don't have to sift through all the evidence ourselves and draw conclusions. If an engineer says this bridge will hold 20t, I don't go 'wait this guy can't prove that, he's never tested it, so I'm going to drive my 25t truck over it cause he might be wrong.' I just take his word and act accordingly.

    The only reason there's any debate out AGW at all is because the naysayers have ties to economic interests in fossil fuel production imo. If it weren't for that, everyone would just go 'fuck yeah, let's deal with this shit'.

    We could flip that around. Like this:

    The reason naysayers are galvanized is because of doomsayers who want everybody to live in huts because of an idea for which they have little evidence. Also it's a tool used by pro-authoritarian-government elites to get their way.
