My point is if you want to inform people about climate changes, be accurate with visualisations (i.e. don't equate something quadratic with something linear without being very transparent about this). If you want it to not be arbitrary, put some context with the numbers/scale. Like maybe plot temperature changes vs CO2 over time on a linear scale, and compare with changes that led to previous ice ages on that same scale. Or something of this vein.
