TRIGGER WARNING: In which I use a Mercator projection, expecting you to understand that there are distortions at the top and bottom, like there are in real life.
For John, BLUF: Climate is not uniform along a line of latitude (left right lines).♠ Nothing to see here; just move along.
Which raises the question:

♠ The way I remember it is that lines of longitude are all the same length, running pole to pole, and thus are all "long". Lines of latitude are longest at the Equator and shrink to almost nothing as one approaches either of the poles (North or South) and those are thus not equally long. Sometimes called Meridians (longitude) and Parallels (latitude).
