For more reliable comparison of temperatures, the minimum temperature should be set to zero Kelvin. Otherwise, the colour shown in the visualization is completely arbitrary, and its intensity cannot be quantitatively described.

Strongly disagree. 1. Your chart could be simplified to 'the temperature at every point on Earth is broadly always the same' - is this a useful visualisation? (Perhaps, but surely not at the same level of detail) 2. In your chart, what should the maximum temperature be set to?

Since we're talking about temperatures on Earth, it's statistically more appropriate to use a range which covers just the minimum and maximum (conceivable) temperatures on Earth.

Not sure why you are getting downvoted. In addition to your comment it would be more interesting to see a visualization over the past 5000 years rather than the past 100 years. 100 years is a small sample given the context.
