Gotta love a graph with an x axis of "extremely cold - cold - normal - hot - extremely hot"

Why not put it in numbers? It's not like we are strangers to numbers in degrees celsius or fahrenheit. Only a fool would do axes like that.

There's this at the end:

> Temperature categories are determined by the normal distribution, so that a third of temperatures fall in each of the main three categories: hot, cold and normal for 1951 to 1980. Summer temperatures for each subsequent 11-year period are compared to the 1951 to 1980 baseline.

It's not so stupid. It essentially drives home the point that a day that in the 1951-1980 period would be considered "hot", today would fall inside the "normal" range.

That is, your normal distribution of temperatures has shifted a bit to the right.

Re:Summers Are Getting Hotter by cbcoutinho on Friday July 28, 2017 @04:36PM (#14877369)
That depends on whatever the local mean and standard deviation is for the locale you're talking about. Absolute temperatures are meaningless in that context
Re:Summers Are Getting Hotter by beat on Friday July 28, 2017 @04:42PM (#14877416)
Absolute temperatures in that context are not so much "meaningless" as actively misleading. Measuring in terms of standard deviation is much more precise and relevant, even if it feels less concrete to those not versed in statistics.

This article is an example of why I find it difficult to intellectually buy into the warming climate theory. It would seem if one is trying to convince the public of "global warming" or "climate change" or whatever the current term is, that scientists would at least publish articles that lay-scientists like myself could read and be convinced. But that's not what we have here, no what we have here is a hyped-up oh my its getting hot article...

First off, your observation of the ridiculous x-axis labels. Really, "Extremely Hot" Is that supposed to scare me or something?

Second, what does this mean...

"...compared actual summer temperatures for each decade since the 1980s to a fixed baseline average." Did you sample at the same location each summer? Did you sample at the same point in the summer? Did you account for any changes in winter/spring/fall temperatures?

And finally...did they happen to point out the time periods are not all of the same length?

Re:Summers Are Getting Hotter by tstactplsignore on Friday July 28, 2017 @04:00PM (#14877066)
Dear lord... it's revealing how little effort you will put into any research or understanding of these results. You come off as proud of your ignorance, and it's not the article's responsibility to cater to your obtuse and idiosyncratic response.

These are average summer temperatures for a network of land based temperature sensors across the entire Northern hemisphere. Please read the source link at the bottom of the article before you ask such frivolous questions. Do you think this work was done by some lone guy in his garage? It's the results of a global dataset that dozens of scientists work on and mantain...

Conveying scientific research just feels impossible when this is the kind of response you can get even on a more educated place forum like HN. Depressing...

Re:Summers Are Getting Hotter by yk on Friday July 28, 2017 @04:25PM (#14877276)
There is really no shortage of introduction articles, starting from Wikipedia:

https://en.wikipedia.org/wiki/Global_warming

or Nasa:

https://climate.nasa.gov/

or by now, just inspecting the measured global temperature by eye

https://data.giss.nasa.gov/gistemp/

Of course, these are introductory texts, so you should expect that there are some simplifications. You can of course just read the IPCC report,

https://www.ipcc.ch/report/ar5/syr/

however be advised that they are on the cold side of the estimates. (Really if you would read the IPCC report with the same critical eye you are trying to nitpick the NY times, you would see that each and every scenario includes at least a plateau in emissions, they just don't have a scenario were emissions just rise like in the last 100 years.)

> First off, your observation of the ridiculous x-axis labels. Really, "Extremely Hot" Is that supposed to scare me or something?

You could of course inspect the linked paper, "Extremely hot" refers to summers that were once in thirty years hot in the time period from 1951 to 1980. It is just an accurate label.

Re:Summers Are Getting Hotter by jack9 on Friday July 28, 2017 @05:06PM (#14877576)
"Extremely hot" without predicated value is cannot be an accurate label in any context. It's a relative label, alone. In this case it's means "largest positive normalized value". The proposition that it is accurate by existence on a graph, is dishonest. That isn't constructive.
Re:Summers Are Getting Hotter by wlesieutre on Friday July 28, 2017 @07:30PM (#14878421)
Yes, they are relative values. The whole point of the article is to make a relative comparison of temperatures now to what they used to be. It's not trying to present absolute measurements.

The average reader gets no meaningful understanding from "Global average temperatures are up 0.5 degrees Celsius.

But looking at a graph like what's presented here, you can realize that a person in 1950, if asked what the weather was like on one of those red days, would tell you "It's goddamn hot, I can't remember it ever being this hot here." and now we get those temperatures all the time.

If you want raw data and absolute comparisons, there are plenty of places to get it. This is an NYT article written to help people understand in concrete terms that things have changed.

Re:Summers Are Getting Hotter by yk on Friday July 28, 2017 @05:57PM (#14877928)
Any label needs context, consider the label "3" or even "9 m/s^2," the first can refer to anything the second to an acceleration or to a gravitational field strength. In the case of weather, "extremely hot" is just what one would call a summer that is hotter above the usual variability. I would argue, that the label is rather good for the context of a NYT article in that the reader would refer to that category as "extremely hot."

You're not a 'lay scientist' if you're just parsing newspaper articles, while ignoring the methodological explanation and cited sources.

You're just nitpicking at a short interactive widget, simplified for a general audience, as if it were the core argument of a paper in an academic journal - which it isn't.

You're not doing science; you are role-playing a character on the internet, and offering your intellectual laziness or lack of comprehension (idk which) as if it were a counter-argument - which it isn't.

It's true that this article solicits your interest in a phenomenon and does not walk through the full detail of everything, but provides only a short summary and a reference to sources. It'd be great if it were a fully-developed explainer that you could navigate through like a science documentary on one particular subject or a deep dive into Wikipedia. Maybe in a few years we';; be able to produce such elaborate tutorials on the fly using AI, and by asking astute questions you'll be able to interactively broaden your education or even make valuable suggestions from left field, and then you will indeed be a lay scientist. But in the meantime, you're LARPing.

Re:Summers Are Getting Hotter by UncleMeat on Friday July 28, 2017 @05:31PM (#14877741)
Yet your problem with the x-axis goes away once you actually look into the methods. This sort of immediate conclusion that a study is worthless because a quick glance from non-experts reveals something that looks a little odd is just awful.

Do you think that no reviewers ever think of these things?

Everything today in "science" is just based off of pretty charts and cartoon graphics. That's their "proof".

The hottest I've been in was in Sep. 2006 in Waco Tx [0]. Mainly due to a hurricane in the gulf that pulled the humidity out of the air, but it wasn't so bad. Road my motorcycle to work that day. Summer 2007 was even stranger, rained almost every other day and temps never made it above 100 that year. Now I'm farther south. I was going to replace my A/C unit in 2015 because it couldn't keep up in the 104+ summer that year. But for the last two summers, it hasn't gotten above 101 and the A/C has been working fine, so here I sit.

This is mindboggling anti-intellectualism. There is absolutely zero substance to your claim. Scientific work is more rigorous and quantitative than ever, especially in climate science, and the fact that you are too lazy to learn the first thing about how modern science works doesn't change that reality. All I can say is I'd really, really wish that you'd educate yourself on how science works. Please start by reading some scientific journals, Nature Geoscience and Geophysical Research Letters are a good place to start.

This isn't an effective way to engage with and change someone's point of view, and there's plenty of science on that. It may be intellectually satisfying to you personally, but that's no better than what you are denigrating here. If you actually care about the cause you profess to be for with your actions, please find a different way to express it, lest you hurt while trying to help.

Upvoted because you're right. But honestly, I wasn't trying to engage with that poster: I was trying to engage with readers, by fighting this kind of nonsense simply by calling it out as such. I wish I could respond with a substance filled, evidence based response to such a claim, but where would I even begin with such a thing? His claim itself is so vague and unsupported that it's more of an emotional feeling than an opinion that can be criticized. Perhaps someone better than me should try.

That's a valid reason to respond as you did. It was my assumption that you were targeting that towards the parent which was in error.

> I was trying to engage with readers, by fighting this kind of nonsense simply by calling it out as such.

That works well for getting people who agree with you to take notice. Unfortunately, if you don't use that to make a new argument to those that already agree with you, you're just preaching to the choir. I don't really have a problem with that, and I wouldn't have called it out if I interpreted it as that, but I also don't think it's all that productive (that's not really meant to be a critique, I'm just explaining my personal point of view on this at this point).

> His claim itself is so vague and unsupported that it's more of an emotional feeling than an opinion that can be criticized. Perhaps someone better than me should try.

When I can summon the strength myself to engage, I find that asking for more details and asking people to actually explain in more detail their belief works well. Often I find that what initially seems like an opinion completely unfounded in facts has some basis, but people are reluctant to go into them because of dismissive responses.

I'm sure we all have a few opinions like that, where we would love to have a good discussion on it, but it's become decisive enough that trying to start a substantive conversation and keep it one track is hard when people make large assumptions about the details of your opinion without actually asking. For example, try starting a conversation on actual differences in how the brain functions between the sexes, and whether that does or does not lead to specific advantages or disadvantages for one sec in certain types of thinking, and whether that advantage if it exists is completely subsumed by environmental factors. I suspect that conversation will quickly approach uselessness if it gets any traction. Some discussions still have far too much cultural and social baggage to happen fruitfully in public, even here, where I'm sure a larger than normal percentage of people would identify as rational intellectuals.

Re:Summers Are Getting Hotter by spaceseaman on Friday July 28, 2017 @04:50PM (#14877482)
How so? The poster displayed a clear example of anti-intellectualism. It's a claim that there is no proof besides "pretty charts and cartoon graphics". Who exactly here isn't engaging? I suppose the old saying holds true here: At least you've found a way to feel superior to both of us.

To actually address your point, however. There is both a breadth and depth of scientific literature, which goes much beyond this nonsense of only "pretty charts". Even reading the linked article in the above nytimes article gives the detail the poster asked for.

Scientists work hard on this. They're not "making it up". They're not lazy. They're not just trying to get rich. Have you spent the last 10 years studying climate change? Have you read all the literature on the subject? From people who have claimed that it was human-driven or not, from scientists across the world and political spectrum. Scientists have. Their entire job is to stay up to date on the current research everywhere in their field.

When you have a problem you don't understand, or don't have enough information about, or don't have a good solution for, what do you do? You ask the expert. The scientists are the experts, and the scientists have a consistent, well-explained consensus on their positions (read the IPCC report for this exact thing). People's resistance to this consensus comes because of two reasons and two reasons alone. 1.) People don't understand climate change because it moves slowly, imperceptibly, and then violently. Climate is far away from an intuitive thing to study, and people's expectations for what's 'logical' in this case is in fact, not always 'logical'. 2.) People's preexisting political affiliations or preconceptions have colored their view. They believe that any position taken by Democrats must be a conspiracy, or ascribe to whataboutism and "moderation". "They're so adamant about this position! But both sides are wrong, so they must be wrong somehow!"

It's nonsense. The fact that so called "intelligent" programmers so easily fall for this garbage is sickening. People claim to be skeptical or logical, but it's all the same stuff with a different lens. Programmers are just as flawed, make their decisions on the same mindless emotional feelings, and don't question anything.

Reading the comments on this post made me lose faith that we will ever address any difficult political and societal challenges. We'll just argue for decades about whether they "actually exist".

Re:Summers Are Getting Hotter by anigbrowl on Friday July 28, 2017 @04:41PM (#14877404)
Why? I don't know whether the person in question is trolling or not, but the stated unwillingness to study the data pretty much disqualifies any value that person's opinion might have. Expecting advocates of good environmental policy to convince every last intellectual holdout (who may or may not be sincere) is unreasonable. It's like demanding that NASA get buy-in from the flat earth crowd.
Re:Summers Are Getting Hotter by kbenson on Friday July 28, 2017 @05:16PM (#14877632)
Because stating observations, whether true or not, isn't always an effective way forward. I was working under the assumption that the response was intended for the original commenter, which may have been assuming too much, but when it can be summarized neatly as "You're wrong. Your whole way of looking at this is wrong. Everyone else is right, and you need to just accept it." but with different words, I think it's not effective at engaging with that person. I think that the recipient of that might feel less inclined to accept an alternative point of view if that's how the interaction starts.
Re:Summers Are Getting Hotter by anigbrowl on Friday July 28, 2017 @05:56PM (#14877923)
There is no effective way forward with someone who insists that they're unwilling to be persuaded.
Re:Summers Are Getting Hotter by kbenson on Friday July 28, 2017 @06:20PM (#14878065)
I don't think that's what we have here. We have someone that's not persuaded by what they've seen. Has anyone asked why? Even if someone is wrong, that doesn't mean they don't have something important to contribute.

I'm just sad the the first response wasn't something along the lines of: "Why? What does the graphic being a cartoon have to do with how accurate the data and the point it's trying to express is? Why are your experiences in a specific region supposed to map directly towards the overall global scenario? Why are you using hottest days in summer in your observation instead of total hot days, which is actually what's being discussed, since it's possible for the average to be much hotter, even if the largest outlier isn't as high for that year, right?"

Re:Summers Are Getting Hotter by anigbrowl on Friday July 28, 2017 @07:40PM (#14878466)
Ars longa, vita brevis

It is not the responsibility of sensible people to persuade every last person in existence of the wisdom of a course of action; that's a recipe for paralysis.

What we have here is someone who expressed an aggressively ignorant counterfactual position and rebuffed polite encouragement to consult primary sources. Perhaps the person is trolling, perhaps they're just a fool, but either way people who make objections in bad faith do little other than waste time, and making endless excuses for them is a further waste of time.

This is why I said elsewhere on the thread that it's time to just move on without the buy-in of that part of the population that rejects the reality principle.

Re:Summers Are Getting Hotter by esaym on Friday July 28, 2017 @04:13PM (#14877167)
Why? So I can see more pretty charts and cartoons? I'm am not telling you my option, I am telling you my observation.
Re:Summers Are Getting Hotter by tstactplsignore on Friday July 28, 2017 @05:05PM (#14877566)
So you can learn something about scientific findings. Their texts are quite thorough, and the data is there- it bewilders me why you're complaining about a figure for every 1000 words of text (normal ratio for a scientific paper). I don't think it's your opinion, or your observation- just some raw emotional feeling born out of a dislike for science and the people who do it.

I will try to engage with you. Here is a typical paper from Nature Climate Change this week. Can you explain exactly why you think the text has not enough substance and is overly reliant upon figures?

> Everything today in "science" is just based off of pretty charts and cartoon graphics. That's their "proof".

I would say the pretty charts and "cartoon graphics" are in direct response to people not actually examining the numbers, and discounting the way it's expressed/reported in the media. To be fair, getting to what a paper is really saying in a media announcement is sometimes an exercise in dissecting the Pr to do away with the hyperbole, but these graphics are actually a way to combat that. As long as they are built using the core data, it's another way to express what's going on, and hopefully in a way that captures people's attention better than the headlines they are already dubious of do.

Let's turn the premise around. Assuming the conclusions are correct and summers are getting hotter, how would you communicate that to someone like you who is rejecting that based on their personal experience, and has (presumably) already discounted the headline, the graphics meant to convey the same idea, and the underlying data they are presented from (whether through actual distrust of the data or distrust of the summarization to the point of not bothering to check it). If it's true, and we have data to show it, how should it be presented?

Re:Summers Are Getting Hotter by wlesieutre on Friday July 28, 2017 @03:56PM (#14877029)
Because the values are normalized to what used to be typical in each measurement location. You can't do an Earth-encompassing graph like that in degrees C because what passes for "normal" or "extremely hot" in Los Angeles is very different from Seattle.
