Unlike temperature, proxies can often be measured historically, although never without error.

Can you tell the difference between 22, and 21, years ago in an ancient chunk of coral? These are the two classes of measurement error. A statistical model between the proxy and the temperature, both measured in present day, is then built. Statistical models have internal guts, things called parameters.
One or more of these parameters will relate how the change in the proxy is associated with the change in the uncertainty of the temperature. Not change of the temperature: Usually, and unfortunately, what happens is that these parameters are mistaken as the temperature and not its uncertainty.
That is, the proxy measured at 20, BC is fed into the model and the parameter effect is reported. The uncertainty in this parameter effect, sometimes called a confidence interval, might also be reported. But these are always beside the point.

Who cares about some dumb model? Not only the prediction, but also some indication of the uncertainty in the prediction should be given. The website xkcd did not show any uncertainty. So he, and climatologists, make it appear that we know to a great degree just what the global average temperature was a long time ago. The errors made thus far fool modelers into thinking they know much more than they do. The parametric confidence intervals tell us of the model guts and not about the temperature, and so using only these intervals guarantees over-certainty, and a lot of it.
The combined effect of forgetting about the measurement error is to produce uncertainty bounds that are again too narrow because of the first measurement error typeand they produce graphs which are way, way too smooth because of the second.
These errors are why. The bottom portion of the cartoon.

Start around Anno Domini By that time, thermometers are on the scene, meaning that new kinds of models to form global averages are being used. Because we can measure temperature in known years now and not thenand we need not rely on proxies, the recent line looks sharper and thus tends to appear to bounce around more. The effect is like looking at foot tracks on a beach.
Close by, the steps appear to be wandering vividly this way or that, but if you peer at them into the distance they appear to straighten into a line.
Call our misperceptions of time series on which xkcd relies for his joke statistical foreshortening. This is an enormous and almost always unrecognized problem in judging uncertainty. There is one error left. From Anno Domini to xkcd shows dashed lines which are claimed to be temperatures.
They are guesses from climate models. It is a gag-a-day comic, and generally does not have a continuing plotline or continuity though there are occasional short story arcs.
Originally a relatively unknown set of personal sketches and doodles, it grew in popularity in when other webcomics such as Dinosaur Comics began linking to it. However, it was when Randall posted a " Map of the Internet ", and said map was subsequently featured on Slashdotthat xkcd's popularity truly erupted. Since then, it has been among the most well-known of webcomics. Of course, you wouldn't know that just by looking at the comic.

The characters are still drawn as very basic stick figures, with no facial features other than hairstyle which is often used to distinguish males and females. However, there are three recurring characters who can be recognized by their respective headgear: A beret-clad Cloudcuckoolandergenerally thought of to be an Existentialist, albeit one with a thing for pastries.
A dark haired woman, referred to in several comics as "Megan"; she shares many of the same interests with the nondescript Author Avatar and is commonly shown to be in a relationship with him.
Was the main character of the "Choices" Series. There also seems to be a recurring main character with a distinct personality most likely the author's ownbut since he looks exactly the same as all the other stick figures without hair or hats, it could be argued that he's just a stock character.
