What I and most of the "deniers" questioned falls into 2 categories.

Actually, no. You're falling for the false-consensus effect. There are a whole lot of different "denier" opinions, but yours is not one of them. You are making false cause with people who actually think that you're a deluded global warming apologist. The people who are correctly labelled as deniers are those who actually deny that global warming is happening. Generally, they deny that the greenhouse effect exists, that CO2 is a greenhouse gas, or they deny that man is producing significant amounts of CO2.

The people, like you, who claim that the models are overstating future warming and that unchecked global warming won't dangerous are luke-warmers, not deniers.

Most of the models Ive read about show that human activity is only a tiny sliver compared to other factors, especially water vapor from evaporation.

Let me explain a bit here. Water vapor is effectively constantly at saturation in the atmosphere, evaporation and precipitation keep it relatively well balanced. The major factor that determines how much water vapor is in the atmosphere is temperature. So, it's a feedback effect, water vapor amplifies the warming caused by other factors such as CO2 and Milankovitch cycles. Additionally, CO2 gets the lion's share of attention because it's a long lasting gas and we produce a lot of it. It will likely take centuries for CO2 levels to fall back to pre-industrial levels even if we cut emissions to zero right now. Other, more potent gases, tend to have half-lifes that are measured in years instead of decades or centuries and we produce orders of magnitude smallers amounts of them. So while CO2 is a relatively weak greenhouse gas, we produce a lot of it and some of the other gases, like water vapor, amplify it's effect.

There's this thing called the internet. Perhaps, you've heard of it? It would be quite easy for all these supposed scientists who supposedly are being censored to form their own website (or journal even) and publish the papers that are supposedly being censored.

Of course, that actually has been attempted a couple of times, but on every occurence that I know of, it turned out the papers were rejected because the paper was fundamentally flawed, not because of the claimed political oppression. It turns out scientific journals want you to use facts, logic, and math. Who knew, right?

It's so much easier to claim that you're being oppressed than to admit you wasted months because you made some basic math errors.

Nice try, but no. CAGW = Catastrophic Anthropogenic Global Warming and it describes the point of view of alarmism on climate quite well.

There is no formal definition of what CAGW is, you could even stick to one definition for a single sentence, you used two very different examples of what it supposedly means. All in all, it's useful rhetorical trickery used to make sure you never have to deal honestly with people you disagree with. You always just one goalpost shift away from continuing the argument.

When public narrative out there uses terms like 'greatest moral challenge of our time',

Dealing with AGW may, in fact, be the "greatest moral challenge of our time" but that has nothing to do with your argument. It's a moral question of doing nothing now so we benefit at the cost of our inheritors, or take minor inconvenient actions now and pass the savings on to those who come after us. The cost of dealing with AGW adaptation and mitigation rises the more we delay on taking action. In addition, the atmosphere is a global commons, and dumping CO2 into it is a mostly invisible action. Can the world work together to achieve a universally beneficial goal when it's so easy to cheat the system?

You are free of course to disagree with that assessment, but my simply point is that phrase "greatest moral challenge of our time" does not need to imply that there a catastrophe lurking around the corner, perhaps you have confused it with "greatest mortal challenge of our time" which would indeed imply an incoming catastrophe.

and slogans like 'no jobs on a dead planet',

On the other hand "no jobs on a dead planet" is a union slogan, and slogans are often hyperbolic. It is a catchy phrase that clearly communicates the point that job concerns and environmental concerns are not mutually exclusive. It is possible that I am projecting my own views onto such groups, but until you mentioned it, I had never heard that particular slogan before.

Maybe you can actually reference skeptics how have done this, flip-flopped on data sets, doesn't change the fact that warming is not as much as projected. And you yourself keep changing your argument without explaining why you are abandoning your prior argument, first it was all statistical quackery, then it's not a big deal this slowdown, and now you are trying the 'a good defence is an offence' strategy by asserting skeptics are cyclical and selective in their datasets, when this is exactly what alarmists are doing by abandoning discussion of trends in favour of discussing instances where Tmax records are being set.

I have not changed or abandoned any of my previous arguments. It is statistical quackery, while atmospheric temperatures are rising slower than projected, those slower periods are common and expected. The quackery is in pretending that this is new and unprecedented and in choosing start and end dates to exaggerate the length of the period. Furthermore, the escalator graph clearly shows how if you followed the behaviour of these self-proclaimed skeptics you could always claim we are in a slow warming, no warming or cooling trend even while the temperature steadily rises. This is expected because the data is noisy and not monotonic. In every non-record year there is a previous higher record year, the slope from that year to any year except the next record setting year will always be below 0. This is simple mathematics and it is critically important to understanding how you are being manipulated. The current "no warming" rhetoric which you occasionally use is no different from the obviously incorrect use that could have been applied to any similar period in the past. Maybe you haven't been following my arguments as closely as you think you have?

Yeah that is interesting, the NASA link though is more about how the histogram of anomalies is trending decade to decade, I assume it is yearly or seasonally adjusted anomalies here, not daily Tmin Tmax records, but it shows a growing fat tail anomaly which does support overall higher likelyhood of max temps.


SKS link is as trustworthy as SKS always is (as in not at all).

Ad hominem, don't attack the site, attack the argument. In this case they provided a link to the paper and summarised the findings, you didn't bother to indicate what you found "untrustworthy about that.

My original point is that record counts in a period of a pause after a period of warming is normal outcome for variable highly autocorrelated data. It does not invalidate the observation of a pause. It is actually consistent with it. The concluding point is that counting record events simply isn't a robust mechanism for qualitative analysis.

Just counting them isn't, but you can do some robust analysis based on frequency and distribution with a sufficiently large time period. For example, in a stable climate you would expect the frequency of extreme events to drop off and for them to be roughly evenly distributed towards warm and cold events. If your results differ significantly from that null hypothesis it indicates that the climate is not stable. That type of analysis can be informative.

When some skeptics make a big deal out of record winter lows, they are shouted down, and rightly so and they are shouted down by skeptics too. But presumably reporting on Tmax records and saying to paraphrase : "on-noes is the global warming!", is perfectly fine. Presumably. Actually... no.... it isn't okay.

Sure, a new daily maximum record isn't good evidence of global warming, but I can see how this argument relates to anything I actually wrote. I was still talking about the "pause" rhetoric and why it's statistical quackery. Specifically, if you choose the last record high as the starting point for a slope you can always choose a recent year where you can show the slope is negative or close to zero. It's deliberately misleading and very common among self-proclaimed skeptics.

CAGW predicted rapid and accelerating warming. But the data fails to bear it out, so post-hoc rationalisations are put forth and the capacity of the hypothesis to yield falsifiability tests is shrinking : which urges the question is the development of this hypothesis robust?

Speaking of fallacies, the use of CAGW is generally associated with a strawman, goalpost moving or loaded language fallacies, depending on context. It's use is rarely associated with honest debate because there is no actual definition for CAGW.

CO2 emission records are actually what predicts accelerating warming, if C02 is a greenhouse gas and we increase the rate at which we're releasing CO2 into the air, we increase the speed at which the planet warms. And rapid is at best a relative term when applied to changes that are far too slow for human senses to observe.

Your comment " Every time we hit a new high temperature", is with respect absurd particularly given admonishments about dodgy statistics in this thread and the OP.

My comment was about the cyclical nature of some "skeptic" arguments. There is always a previous record high which we almost always below, thus the argument can always be made that there has been "no warming" for some time period. The argument goes out of style for a bit after a new record high has been set, but give it a year or two and it comes back into fashion until the next record high is set. The comment had nothing to do with presenting actual evidence of global warming.

An interesting null would be to compare # high temp records against # of low temp records.

It is interesting and has been done. According to that paper, the split for 2001-2011 temperature anomalies was about 85% high to 15% low. According to Skeptical Science, the records were split 67% high to 33% low over 1999-2009.

The danger of CO2 was always advertised as runaway warming, with a feedback loop of warming that could not be ended - not a slow linear ramp up of just 2C over 100 years.

That may be what some people say is the issue, but as far as I understand it, the mainstream science concern is not run away warming that renders the planet unliveable. That's actually considered fairly unlikely in the near-term scenarios. The actual major areas for concern are rising seas, ecosystem disruption, droughts, wildfires, floods, augmented storms and storm damage, heat-related illness and disease, and economic losses.

From what I've read about it, of particular note is that at around +4 degrees Celcius most of our staple food crops likely won't grow very well without extensive genetic modification. I don't understand the details very well, but I think there's an issue with heat stress and the way leaves work. As I understand it, at +4C the photosynthesis process in regular leaves is significantly impaired. Apparently, when the world came down from that temperature there was a massive die off of vegetation, somewhere around 90% of the flora died off, quickly followed by over 90% of the fauna. It's one of the great extinction events. I'm pretty sure that we really don't want to see the same thing happen to our crops and livestock on the way up.

Let me elaborate further on why the SKS graph is a strawman, I assumed my initial comment would be obvious and sufficient. Anyway it is because most cogent skeptics do not dispute that the world was warmed in the 20th century, that warming post 1970 was quite pronounced and that co2 does have a warming effect; these observations are not controversial. The SKS graph implies that skeptics wilfully ignore the observed warming. It is a stupid lie vigorously repudiated, and by virtue of this that SKS continue to publish it makes them wilful liars, wilfully misrepresenting the point of view of their detractors.

Methinks thou dost protest too much.

Seriously, there are, in fact, many "skeptics", cogent or otherwise who dispute that the world has warmed and that CO2 does have a warming effect. For example, Jane Q. Public is a good example of self-professed skeptic on Slashdot who apparently does not believe that CO2 has a warming effect. She has several times posted "proof" that the greenhouse effect can not exist. And she is not alone, I've replied to dozens of posts from many different posters on Slashdot who claimed for various reasons that global warming does not exist. I really couldn't tell you how many more I've read and not responded but it's probably in the hundreds.

The SKS graph does not imply that "skeptics" wilfully ignore the observed warming, it simply shows why "the pause" doesn't matter in the big picture. It's happened before and will happen again, and the underlying trend continues. Frankly, you don't seem to understand that you are doing exactly what that graphs shows is wrong.

Frankly, the argument that the IPCC report deals with "the Hiatus" makes is significant is a non-starter. The IPCC report deals with because it deals with practically everything related to climate change and endless talking heads in the media have made it a significant issue which had to be addressed. To quote from the box you referenced:

"Figure 9.8 demonstrates that 15-year-long hiatus periods are common in both the observed and CMIP5 historical GMST time series (see also Section 2.4.3, Figure 2.20; Easterling and Wehner, 2009; Liebmann et al., 2010)"


There is medium confidence that the GMST trend difference between models and observations during 1998–2012 is to a substantial degree caused by internal variability, with possible contributions from forcing error and some CMIP5 models overestimating the response to increasing GHG and other anthropogenic forcing.


The causes of both the observed GMST trend hiatus and of the model–observation GMST trend difference during 1998–2012 imply that, barring a major volcanic eruption, most 15-year GMST trends in the near-term future will be larger than during 1998–2012 (high confidence; see for a full assessment of near-term projections of GMST). The reasons for this implication are fourfold: first, anthropogenic greenhouse-gas concentrations are expected to rise further in all RCP scenarios; second, anthropogenic aerosol concentration is expected to decline in all RCP scenarios, and so is the resulting cooling effect; third, the trend in solar forcing is expected to be larger over most near-term 15-year periods than over 1998–2012 (medium confidence), because 1998–2012 contained the full downward phase of the solar cycle; and fourth, it is more likely than not that internal climate variability in the near-term will enhance and not counteract the surface warming expected to arise from the increasing anthropogenic forcing.

So yes, the slowdown is real and sure, it should be explained, and not surprisingly, it already has been. The point you don't seem to understand is that arguments about the slowed warming are nothing but a sideshow. Every time we hit a new high temperature we start a new round of "it hasn't warmed since the last time we broke a record". It's tiresome and pointless. That's what the graph is really about, and why you don't like it. You don't like it because it shows clearly why (at least some of) your arguments are vapid.

Although it is quite a clever piece of polemic, it is at heart just a dumb strawman argument and infers a point of view which is not, nor ever was articulated by any CAGW skeptic that I am aware of.

Well you just made one of the arguments that the graph dispells: "The pause is real and merits an explanation", so presumably you know at least one such person. Case in point one of the many points the graph addresses it easy to choose many different periods and say "there is no trend for this period" and confuse that with "there is no trend". In fact, you can pretty much cover the entire temperature record with cherry-picked periods that show no statistically significant warming despite the obvious historical warming trend when you look at forest and not just the trees.

A _good_ site allows people to upvote the signal and downvote the noise

I remember seeing a post on Slashdot a while ago about a study that said that downvoting actually makes the trollers and nutters more pernicious and persistent. So maybe a good site actually only allows upvoting, but starts all posts below the "normal" view level?

Of course, this is nothing new, the same tactics are recommended to deal with "problem" children who attention through negative behaviour (breaking things, tantrums, foul language, etc). I've even seen posters on Slashdot, with a history of being factually wrong and scientifically illiterate, brag about how being downmodded only proves that they are, in fact, correct. They then reach the conclusion that their insightful correctness must be a danger to the dark powers that control Slashdot, or some similar tripe, and that they must continue to battle at all costs. When it seems to me that the reason they were downmodded was because they were posting junk that was stupid and wrong.

It's simple, everyone would rather believe that they are oppressed freeedom fighters rather than ignorant buffoons, even though the latter is far more more frequently true.

New York still hasn't flooded

Are you sure about that? I mean sure not reading the article is pretty common on Slashdot but not reading your own sources is pretty lame. The article you linked says that New York will experience more flooding under storm conditions. The top category of flooding in my linked article for the flooding damager during Hurricane Sandy in New York City is 6-18 feet of water, because the top recorded flooding level was a little over 17 feet of water. There seems to be more than a few buildings in that top category. And the article says the average flooding level in New York city will rise by an estimated 4 feet of water by 2032 (20 years after the article was published). I don't see how that can be considered good evidence for your claims no matter how I look at the issue.

Using the numbers from Venus Atmosphere Temperature and Pressure Profile:
Average Earth temperature: 14 degrees x 1.176 = 16 degrees Celcius
Average Venus temperature at 1 atmosphere (49.5 km above the surface): 66 degrees Celcius

Anybody who denies AGW catastrophism is termed a "denier" and the 97% number is trotted out to refute them.

No, generally speaking anyone who denies that global warming is occurring is labelled a "denier", because the evidence is conclusive that it's happening. The people who deny that catastrohpic climate change could occur because of global warming ir more properly lablled as a "luke-warmer", because they generally don't believe it will get "that hot".

So it's fair to point out that the number 97% is "nonsense" when used for that purpose.

No one (but you) is using it for that purpose.

Even if the paper wasn't shoddy in its methods, its conclusion would be useless for the AGW alarmism debate, because pretty much everybody believes that climate changes and that humans "play a role".

Surprisingly, close to half of Americans don't actually believe that, they think that there's no consensus on whether global warming is occurring. Probably because their primary news sources are under the control of Rupert Murdoch who personally stands to lose money from his portfolio if it's widely acknowledged that global warming is occurring and that human emissions are a key factor. Rupert, in case you didn't know, has a lot of money invested in coal companies which would bear the brunt of the effects of regulation, carbon taxes, or carbon trading markets.
