>I didn't suggest that angular velocity is the same as linear velocity, I asked how you were interpreting the area and velocity, and parenthetically observed that the angular velocity was constant.

If you make tangential observations the conversation may move tangentially.

>You say that the area is impactful - what do you understand it as meaning?

It's a visualisation, i.e. the visuals are meant to contain the meaning, and said visuals are important and need to be carefully considered. Areas of 2D shapes tend to represent some kind of quantity, where the area is proportional to the quantity (and if the area was quadratically related to the quantity that would be misleading or inaccurate).

>Surely you can agree that if the largest anomaly shown was 0.01 C then the graph would have far less impact, and if it was 100 C then the graph would have far more impact?

The point is about the meaning of the choice of visualisation and the choice of data and context provided. That's why I compare with 0.01C, because to the layman 2C and 0.01C are both not significant, but the actual environmental impact of the 2C could be very much more significant with more context. You don't need to be very informed to know 100C is significant.
