But in these graphs they are mostly related to organisms, through which any local temperature «signal» is noisy — which means it has a lot of
error bars on it.
In our next post, we will look
at error bar plots, which can tell you this.
They, and many many others, desired to
produce error bars to give some sense of the uncertainty of their result.
When the
known error bars are added to the reported annual temperatures since 1998, one discovers that multiple previous years may have been warmer than 2014.
If one
wants errors bars, one should at least have them centered properly, and not play with the scale..
In the case of 50 or 65
knot error bars, the order of magnitude is still right, and that can be pretty good.
