Is nobody else having a problem seeing the comic? Both here and on XKCD I get an "Image not found" icon, a blue question mark. I thought maybe this was an interactive comic that doesn't work on my iPad (like that garden thing, though that did nothing on my computer either). If I tap it on XKCD nothing happens, here it leads to the picture's Wiki page - also with the question mark - which says it's a PNG, which I know this iPad can show.

Okay, now that I've managed to SEE the damn thing, I have a question. There's no mention of why this is using "BCE" and "CE" instead of the standard "BC" and "AD", never mind what these stand for (thinking and thinking about it, my guess is "Before Christ Era" and "Christ Era"). This is the kind of thing that should be mentioned on ExplainXKCD, LOL! Fun fact: when I searched this page for "BCE", to confirm it wasn't explained, I got "Over 100 matches". :) Anyway, I figure maybe those are currently accepted scientific terminology, especially since "AD" is Latin, unlike "BC", but the average person still uses BC and AD. In fact, I think this is the first time I've ever seen BCE and CE (unless it's been on XKCD before and I just dismissed it as a typo or something. This time there are WAY too many for it to be a mistake every time, including here in the explanation!) - NiceGuy1[[Special:Contributions/108.162.218.239|108.162.218.239]] 21:20, 14 September 2016 (UTC) I finally signed up!

:::I assume nothing. My statements are completely accurate. I OBSERVE it is the standard, the only standard anybody (else) seems to use. BC/AD is the "standard" because it is standard practice to use it. For good reason, since I would estimate just about everybody knows what it means, while I am sure I am in the majority in having never heard BCE/CE. It is also not "my" way, I made no choice here, it is the established convention, it is the way accepted and adopted by society. While I would normally be more inclined towards terminology devoid of religion (as seems to be the point here, now that someone kindly clarified these acronyms for me), I feel this would be a losing fight, one it would be foolish to attempt, the classic terminology is too ingrained in society.

What this comic doesn't show is what kind of changes occurred in the previous interglacial period as opposed to the current one.  Since the current one is not yet over there could still be a stage of an interglacial with rapid temperature rise which we are only now reaching, but has happened in previous interglacial periods.

I think this would be first time where I see global thermonuclear war described as "best case scenario". There was and still is lot of discussion about how much is current warming caused by humans, but that's not important. Important question is "can we stop it?" and the answer is "not without literally billions of dead" (and even that might not suffice). Any money currently used for most plans to reduce CO2 (which usually fails to reduce CO2, not speaking about global warming, but succeed in their main goal, which is moving the money into pockets of their proponents) would be better spent on ADAPTING to the change. Only plans for reducing CO2 actually worth doing are the ones related to stopping burning fossil fuels, because we will soon need fossil fuels to make food (and other stuff) from. Oh, and also stop burning FOOD. So we should replace fossil fuel power plants with only viable alternative - NUCLEAR. So called renewable power sources like solar are good addition, but doesn't scale to the amount of power and stability we need. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 14:12, 15 September 2016 (UTC)

I understand the concept behind this comic, but why doesn't the graph include atmospheric CO2, sulfur aerosols, and solar 10.7cm radio flux for comparison?  Also, for the person who suggested we look at previous interglacial periods, I may be wrong, but I believe a lot of that data comes from ice cores, that would make it hard to look at time periods before the present ice sheets existed.  IIRC, there were periods not too long ago (geologically speaking) where Antarctica was covered in lakes, tundra, and sparse forests instead of ice sheets.[[Special:Contributions/172.68.65.127|172.68.65.127]] 05:08, 16 September 2016 (UTC)

The jump of 0.5 degrees from 2000 to 2016 has been shown to be false.  It exists because "scientists" went back and changed (or "seasonally adjusted") their data to fit their preconceived conclusions.  Just look at Al Gore's 'Inconvenient [Non]Truth', pretty much every doomsday scenario has not occurred.

:I think the point of comics is that while there were changes in temperature before, they were never this rapid.

::Yeah, the long sample intervals and best fit curves from pre-industrial temperature estimates tend to smooth out any rapid changes that may have occurred over the time period (Think of an ECG/EKG that took a single instantaneuos microvolt sample once every 15 minutes of your life from birth to death, the resulting deflection graph would not look like anything like a normal heart rhythm, but it could be interpreted as the average electrical activity of your heart over the course of a lifetime).  It's true that the rapid climate shifts we are able see in geological records usually coincide with things like supervolcano eruptions and asteroid impacts.  But those shifts are usually to the negative end from the nuclear winter effect.  Idea for reversing global warming without affecting CO2 emissions, just send a couple of hypervelocity rods or a gravity-tractored asteroid into a dormant supervolcano caldera every few years and... instant winter.

Very interesting and important work.

Actually.... Solomon and Jesus are not historical figures. Outside the Old and the New Testament, there is no archaeological or other evidence for their existence. I suppose, Jesus has played a significant role in history. So, you may be justified to add an entry saying something like "Date that religious traditions hold as the date of birth of Jesus."

Then, if you mention, say, Shakespeare, then you should also mention the estimated composition of the Bible, an event with more important historical influences.

Roman empire was continued for more than thousand years (Eastern Roman Empire, today reffered as Byzantium).

Current scholarly wisdom is that the Homeric epics, (the Iliad and the Odussey) were composed at the second half of the 8th century, perhaps around 720 BCE.

: First, the Guardian is a newspaper, not a science journal. Second, that article is from 2013, before the latest upsurge. Third, even ignoring those things, the article doesn't say what you claim it does. The single most optimistic sentence I see is ''"If we are lucky, the impact of burning all that oil, coal and gas could turn out to be at the less severe end of the plausible spectrum."'' The rest of the article is quite pessimistic, such as ''"it is overwhelmingly likely that we would shoot well past 2C and towards 3C or even 4C of warming."''

It says that in order to '''possibly''' reach the "optimistic" +2° scenario (Randall's 2nd line, not the 1st one), we would need to cut anthropogenic CO2 to about 1/10th our current level, which is ridiculously unlikely to happen.

Wind has been in competitive equilibrium with coal since 1995, and solar hit grid parity early this year and is expected to continue falling in price about as fast at least until 2035. Is there any reason to believe fossil fuels won't be abandoned by 2030? [[User:JSalsman|JSalsman]] ([[User talk:JSalsman|talk]]) 02:01, 3 November 2016 (UTC)
::::: Exactly zero words in your explanation discuss how the linked graphs show the existence of a better scenario than the ones listed in the timeline. Your very first graph, from the Guardian, explicitly says '''50% chance of not exceeding 2°C''', which is Randall's middle scenario. That means '''it supports exactly what Randall is saying.''' It says absolutely nothing about a scenario better than the "best case" timeline. - [[User:Frankie|Frankie]] ([[User talk:Frankie|talk]]) 21:06, 3 November 2016 (UTC)
::::: Do you understand the words that I am saying? The words that I have been saying from the start of this conversation? I don't f***ing care about pie in the sky energy projects. '''Even if your energy claims are correct, they don't say a single d**n thing about beating the +1.2°C curve.'''. - [[User:Frankie|Frankie]] ([[User talk:Frankie|talk]]) 21:13, 3 November 2016 (UTC)
:::::: I apologize. I confused the +1° mark with +2°. The labels are so far above at the top. You are correct. I will forgo uploading the graphs as we are now in agreement. [[User:JSalsman|JSalsman]] ([[User talk:JSalsman|talk]]) 22:23, 3 November 2016 (UTC)

== Interesting Ways to Look at it. ==

Hey, I had a great time scrolling down and watching the earth heat up :).[[Special:Contributions/108.162.245.115|108.162.245.115]] 19:47, 17 October 2016 (UTC)

ICYMI, [https://www.cato.org/ Cato] provides an [http://www.cgd.ucar.edu/cas/wigley/magicc/ IPCC MAGICC] [http://www.cgd.ucar.edu/cas/wigley/magicc/UserMan5.3.v2.pdf climate model] simulator for [https://www.cato.org/blog/current-wisdom-we-calculate-you-decide-handy-dandy-carbon-tax-temperature-savings-calculator anyone to examine]. FWIW, I side with {{w|Bjorn Lomborg}}, who famously champions a [http://www.lomborg.com/ middle way] in climate science for the sake of [https://www.washingtonpost.com/news/in-theory/wp/2016/09/19/when-it-comes-to-climate-change-lets-get-our-priorities-straight/ downtrodden peoples around the world].

== Fact checking the chart on Stack Exchange ==

I posted a question on Earth Sciences Stack Exchange about how the {{w|Younger Dryas}} fits into this comic: http://earthscience.stackexchange.com/q/9103/6973

There was also an existing question about the chart's general accuracy: http://earthscience.stackexchange.com/q/8746/6973

== Translation of the Morse code message ==

The translation of the explanation in "Telegraph", written in Morse code, is: "Now, the mother of Samuel Morse always sent the lad out on a horse." [[User:Agusbou2015|Agusbou2015]] ([[User talk:Agusbou2015|talk]]) 15:56, 28 May 2017 (UTC)

== "Sad comics" ==
<blockquote>...So after the election of a climate change denier later in the year of this comic's release, several sad comics have been posted. Some of the reason could be that Randall no longer believes that even his worst fears (as expressed by the current path at the bottom) will hold up, when USA gets a president, who will on purpose act in a way that scientist claims will make the temperature rise even more. See more here.</blockquote>

I've mentioned this on the talk page for [[2137: Text Entry]], but I'll reiterate it here: this observation is not factual, not relevant to the explanation, and does not belong in the description of this comic. If you read it in context, you will see that it is also a non-sequitur, clumsily inserted after one or two factual sentences - it does not follow from anything prior in the discussion. It is poorly expressed and the point being made is unclear in any case.

While the user doing this may well have honest intentions, they are simply defacing articles with their own anti-Trump projections and spamming a link to their own, misleadingly-titled page ([[Sad comics]]) which has no clear meaning or explanatory value.

The industrial revolution and its consequences have been a disaster for the human race, and this graph shows it.[[Special:Contributions/172.68.50.19|172.68.50.19]]
:I agree that it has probably been a disaster (certainly a gamechanger) for the ecosystems, causing changes and challenges that are so much different to what everything else woupd have experienced without such a heavy hand of humans upon the planet. But for "the human race",vI wonder if there'd be so many billions of us if industrial (and post-malthusian) developments had never arisen. By a simplistic numbers game, we are (currently) ranking higher than it seems likely a more nature-tuned alternative 20th/21st-Century would have looked like.
:A higher population doesn't guarantee "success", I know, and only hindsight will say for sure whether unprecedented growth leads to unprecedented decline in the same 'scoring' value (indicating that it isn't the best score to use long-term), but some would say this. (Not me, I'm just philosophising here.)
:Beyond this, if only by entering the Industrial Age do we have the ability to foresee and forestall some asteroid impact..? Perhaps then the (somewhat damaged) ecosystem actually lives on 'better' (subjectively) from our flawed attempt to industrially improve the planet, to our own ends, the rediscovery of ecoprinciples and then the successful aversion of another planet-killing asteroid (or at least the development of "arks" to let the current biodiversity to ride out the problem, here or elsewhere). Unless you have the view that the post-now changes (like the post-dinosaur/etc changes) are themselves higher scoring on the nature-scale. (But then if an unaverted asteroid is equal to a prior one, then is our polluion of the world equal to when earlier organisms started to fill the atmosphere with deadly oxygen and convert the world to an entirely different phase of life?)
:What can definitely be said is that we're doing ''something'', but expect some people (who aren't actually full-on deniers) to suggest that it isn't really a bad thing. Which it probably is, of course. Or at least not the ''best'' thing, and there's probably better outcomes than the one we're tumbling into, by whatever measure.
