    The color grading of the years is really bad. The last 20/30 years are all very low in contrast compared to each other, while 1940s and 60s are easy to tell apart, where it is least important. There are so many more colors than yellow/orange/brown, we can use them to get more information density.

      Quite the contrary. I have a red-green deficiency (and so do about 6% of men). Viridis Color scale is pretty nice but two much colors are hard to read for a lot of people

          Actually, that’s a feature that was common going all the way back to the very earliest image file formats: https://en.wikipedia.org/wiki/Indexed_color

          It’d be easy enough to make the chart a plain old GIF or indexed PNG; the only non-trivial part is that you’d need add some code to the page it’s embedded in to swap out the color palette. (You could also make it an SVG and manipulate it even more easily using the DOM.)

            Well, the image format is based on indexed color for compression purposes … But it’s not like it calls out “these indexes should be customizable”.

    Why does it seem like this is only the northern hemisphere and not truly “global”? Shouldn’t it be warm in the southern hemisphere when it’s cold in the north? So shouldn’t these groupings generally hover around an average between northern and southern hemisphere temps?

      What’s your source that there’s not warming in the southern hemisphere?

      The temperature readings would look different because winter and summer are flipped, but they absolutely should be attributing a similar effect.

        That’s what I thought… But if it’s winter in the north then it’s summer in the south, so you’d expect them to average in a way that you wouldn’t see such stark differences between say January and July. In July it’s winter in the south, summer in the north. Intuitively I’d assume they’d average. Temps would still be rising year over year, but you wouldn’t see a difference between months. A couple people have answered that it has to do with the earths tilt and the fact that there’s more landmass in the north. Seems plausible I guess.
